NET Core 3 WPF MVVM框架 Prism系列之導航系統

文將介紹如何在.NET Core3環境下使用MVVM框架Prism基于區域Region的導航系統

在講解Prism導航系統之前，我們先來看看一個例子,我在之前的demo項目創建一個登錄界面：

我們看到這里是不是一開始想象到使用WPF帶有的導航系統，通過Frame和Page進行頁面跳轉，然后通過導航日志的GoBack和GoForward實現后退和前進，其實這是通過使用Prism的導航框架實現的,下面我們來看看如何在Prism的MVVM模式下實現該功能

一.區域導航#

我們在上一篇介紹了Prism的區域管理，而Prism的導航系統也是基于區域的，首先我們來看看如何在區域導航

1.注冊區域#

LoginWindow.xaml：

Copy<Window x:Class="PrismMetroSample.Shell.Views.Login.LoginWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:PrismMetroSample.Shell.Views.Login"
        xmlns:region="clr-namespace:PrismMetroSample.Infrastructure.Constants;assembly=PrismMetroSample.Infrastructure"
        mc:Ignorable="d"
        xmlns:prism="http://prismlibrary.com/"
        xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
         Height="600" Width="400" prism:ViewModelLocator.AutoWireViewModel="True" ResizeMode="NoResize" WindowStartupLocation="CenterScreen"
        Icon="pack://application:,,,/PrismMetroSample.Infrastructure;Component/Assets/Photos/Home, homepage, menu.png" >
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Loaded">
            <i:InvokeCommandAction Command="{Binding LoginLoadingCommand}"/>
        </i:EventTrigger>
    </i:Interaction.Triggers>
    <Grid>
        <ContentControl prism:RegionManager.RegionName="{x:Static region:RegionNames.LoginContentRegion}" Margin="5"/>
    </Grid>
</Window>

2.注冊導航#

App.cs：

Copy  protected override void RegisterTypes(IContainerRegistry containerRegistry)
  {
        containerRegistry.Register<IMedicineSerivce, MedicineSerivce>();
        containerRegistry.Register<IPatientService, PatientService>();
        containerRegistry.Register<IUserService, UserService>();

        //注冊全局命令
        containerRegistry.RegisterSingleton<IApplicationCommands, ApplicationCommands>();
        containerRegistry.RegisterInstance<IFlyoutService>(Container.Resolve<FlyoutService>());

        //注冊導航
        containerRegistry.RegisterForNavigation<LoginMainContent>();
        containerRegistry.RegisterForNavigation<CreateAccount>();
  }

3.區域導航#

LoginWindowViewModel.cs：

Copypublic class LoginWindowViewModel:BindableBase
{

    private readonly IRegionManager _regionManager;
    private readonly IUserService _userService;
    private DelegateCommand _loginLoadingCommand;
    public DelegateCommand LoginLoadingCommand =>
            _loginLoadingCommand ?? (_loginLoadingCommand = new DelegateCommand(ExecuteLoginLoadingCommand));

    void ExecuteLoginLoadingCommand()
    {
        //在LoginContentRegion區域導航到LoginMainContent
        _regionManager.RequestNavigate(RegionNames.LoginContentRegion, "LoginMainContent");

         Global.AllUsers = _userService.GetAllUsers();
    }

    public LoginWindowViewModel(IRegionManager regionManager, IUserService userService)
    {
          _regionManager = regionManager;
          _userService = userService;            
    }

}

LoginMainContentViewModel.cs：

Copypublic class LoginMainContentViewModel : BindableBase
{
    private readonly IRegionManager _regionManager;

    private DelegateCommand _createAccountCommand;
    public DelegateCommand CreateAccountCommand =>
            _createAccountCommand ?? (_createAccountCommand = new DelegateCommand(ExecuteCreateAccountCommand));

    //導航到CreateAccount
    void ExecuteCreateAccountCommand()
    {
         Navigate("CreateAccount");
    }

    private void Navigate(string navigatePath)
    {
         if (navigatePath != null)
              _regionManager.RequestNavigate(RegionNames.LoginContentRegion, navigatePath);
        
    }


    public LoginMainContentViewModel(IRegionManager regionManager)
    {
         _regionManager = regionManager;
    }

 }

效果如下：

這里我們可以看到我們調用RegionMannager的RequestNavigate方法，其實這樣看不能很好的說明是基于區域的做法，如果將換成下面的寫法可能更好理解一點：

Copy   //在LoginContentRegion區域導航到LoginMainContent
  _regionManager.RequestNavigate(RegionNames.LoginContentRegion, "LoginMainContent");

換成

Copy //在LoginContentRegion區域導航到LoginMainContent
 IRegion region = _regionManager.Regions[RegionNames.LoginContentRegion];
 region.RequestNavigate("LoginMainContent");

其實RegionMannager的RequestNavigate源碼也是大概實現也是大概如此，就是去調Region的RequestNavigate的方法，而Region的導航是實現了一個INavigateAsync接口：

Copypublic interface INavigateAsync
{
   void RequestNavigate(Uri target, Action<NavigationResult> navigationCallback);
   void RequestNavigate(Uri target, Action<NavigationResult> navigationCallback, NavigationParameters navigationParameters);
    
}

我們可以看到有RequestNavigate方法三個形參：

target：表示將要導航的頁面Uri
navigationCallback:導航后的回調方法
navigationParameters:導航傳遞參數(下面會詳解)

那么我們將上述加上回調方法：

Copy //在LoginContentRegion區域導航到LoginMainContent
 IRegion region = _regionManager.Regions[RegionNames.LoginContentRegion];
 region.RequestNavigate("LoginMainContent", NavigationCompelted);

 private void NavigationCompelted(NavigationResult result)
 {
     if (result.Result==true)
     {
         MessageBox.Show("導航到LoginMainContent頁面成功");
     }
     else
     {
         MessageBox.Show("導航到LoginMainContent頁面失敗");
     }
 }

效果如下：

二.View和ViewModel參與導航過程#

1.INavigationAware#

我們經常在兩個頁面之間導航需要處理一些邏輯，例如，LoginMainContent頁面導航到CreateAccount頁面時候，LoginMainContent退出頁面的時刻要保存頁面數據，導航到CreateAccount頁面的時刻處理邏輯(例如獲取從LoginMainContent頁面的信息)，Prism的導航系統通過一個INavigationAware接口：

Copy    public interface INavigationAware : Object
    {
        Void OnNavigatedTo(NavigationContext navigationContext);

        Boolean IsNavigationTarget(NavigationContext navigationContext);

        Void OnNavigatedFrom(NavigationContext navigationContext);
    }

OnNavigatedFrom：導航之前觸發,一般用于保存該頁面的數據
OnNavigatedTo：導航后目的頁面觸發，一般用于初始化或者接受上頁面的傳遞參數
IsNavigationTarget：True則重用該View實例，Flase則每一次導航到該頁面都會實例化一次

我們用代碼來演示這三個方法：

LoginMainContentViewModel.cs：

Copypublic class LoginMainContentViewModel : BindableBase, INavigationAware
{
     private readonly IRegionManager _regionManager;

     private DelegateCommand _createAccountCommand;
     public DelegateCommand CreateAccountCommand =>
            _createAccountCommand ?? (_createAccountCommand = new DelegateCommand(ExecuteCreateAccountCommand));

     void ExecuteCreateAccountCommand()
     {
         Navigate("CreateAccount");
     }

     private void Navigate(string navigatePath)
     {
         if (navigatePath != null)
            _regionManager.RequestNavigate(RegionNames.LoginContentRegion, navigatePath);
     }

     public LoginMainContentViewModel(IRegionManager regionManager)
     {
          _regionManager = regionManager;
     }

     public bool IsNavigationTarget(NavigationContext navigationContext)
     {            
          return true;
     }

     public void OnNavigatedFrom(NavigationContext navigationContext)
     {
          MessageBox.Show("退出了LoginMainContent");
     }

     public void OnNavigatedTo(NavigationContext navigationContext)
     {
          MessageBox.Show("從CreateAccount導航到LoginMainContent");
     }
 }

CreateAccountViewModel.cs:

Copypublic class CreateAccountViewModel : BindableBase,INavigationAware
{
     private DelegateCommand _loginMainContentCommand;
     public DelegateCommand LoginMainContentCommand =>
            _loginMainContentCommand ?? (_loginMainContentCommand = new DelegateCommand(ExecuteLoginMainContentCommand));

     void ExecuteLoginMainContentCommand()
     {
         Navigate("LoginMainContent");
     }

     public CreateAccountViewModel(IRegionManager regionManager)
     {
         _regionManager = regionManager;
     }

     private void Navigate(string navigatePath)
     {
        if (navigatePath != null)
            _regionManager.RequestNavigate(RegionNames.LoginContentRegion, navigatePath);
     }

     public bool IsNavigationTarget(NavigationContext navigationContext)
     {
         return true;
     }

     public void OnNavigatedFrom(NavigationContext navigationContext)
     {
         MessageBox.Show("退出了CreateAccount");
     }

     public void OnNavigatedTo(NavigationContext navigationContext)
     {
         MessageBox.Show("從LoginMainContent導航到CreateAccount");
     }

 }

效果如下：

修改IsNavigationTarget為false：

Copypublic class LoginMainContentViewModel : BindableBase, INavigationAware
{
     public bool IsNavigationTarget(NavigationContext navigationContext)
     {            
          return false;
     }
}

public class CreateAccountViewModel : BindableBase,INavigationAware
{
     public bool IsNavigationTarget(NavigationContext navigationContext)
     {
         return false;
     }
 }

效果如下:

我們會發現LoginMainContent和CreateAccount頁面的數據不見了，這是因為第二次導航到頁面的時候當IsNavigationTarget為false時，View將會重新實例化，導致ViewModel也重新加載,因此所有數據都清空了

2.IRegionMemberLifetime#

同時，Prism還可以通過IRegionMemberLifetime接口的KeepAlive布爾屬性控制區域的視圖的生命周期,我們在上一篇關于區域管理器說到，當視圖添加到區域時候，像ContentControl這種單獨顯示一個活動視圖，可以通過Region的Activate和Deactivate方法激活和失效視圖，像ItemsControl這種可以同時顯示多個活動視圖的，可以通過Region的Add和Remove方法控制增加活動視圖和失效視圖，而當視圖的KeepAlive為false，Region的Activate另外一個視圖時，則該視圖的實例則會去除出區域，為什么我們不在區域管理器講解該接口呢？因為當導航的時候，同樣的是在觸發了Region的Activate和Deactivate，當有IRegionMemberLifetime接口時則會觸發Region的Add和Remove方法，這里可以去看下Prism的RegionMemberLifetimeBehavior源碼

我們將LoginMainContentViewModel實現IRegionMemberLifetime接口，并且把KeepAlive設置為false，同樣的將IsNavigationTarget設置為true

LoginMainContentViewModel.cs:

Copypublic class LoginMainContentViewModel : BindableBase, INavigationAware，IRegionMemberLifetime
{

     public bool KeepAlive => false;
     
     private readonly IRegionManager _regionManager;

     private DelegateCommand _createAccountCommand;
     public DelegateCommand CreateAccountCommand =>
            _createAccountCommand ?? (_createAccountCommand = new DelegateCommand(ExecuteCreateAccountCommand));

     void ExecuteCreateAccountCommand()
     {
         Navigate("CreateAccount");
     }

     private void Navigate(string navigatePath)
     {
         if (navigatePath != null)
            _regionManager.RequestNavigate(RegionNames.LoginContentRegion, navigatePath);
     }

     public LoginMainContentViewModel(IRegionManager regionManager)
     {
          _regionManager = regionManager;
     }

     public bool IsNavigationTarget(NavigationContext navigationContext)
     {            
          return true;
     }

     public void OnNavigatedFrom(NavigationContext navigationContext)
     {
          MessageBox.Show("退出了LoginMainContent");
     }

     public void OnNavigatedTo(NavigationContext navigationContext)
     {
          MessageBox.Show("從CreateAccount導航到LoginMainContent");
     }
 }

效果如下：

我們會發現跟沒實現IRegionMemberLifetime接口和IsNavigationTarget設置為false情況一樣，當KeepAlive為false時，通過斷點知道，重新導航回LoginMainContent頁面時不會觸發IsNavigationTarget方法，因此可以

知道判斷順序是：KeepAlive -->IsNavigationTarget

3.IConfirmNavigationRequest#

Prism的導航系統還支持再導航前允許是否需要導航的交互需求，這里我們在CreateAccount注冊完用戶后尋問是否需要導航回LoginMainContent頁面，代碼如下：

CreateAccountViewModel.cs:

Copypublic class CreateAccountViewModel : BindableBase, INavigationAware，IConfirmNavigationRequest
{
     private DelegateCommand _loginMainContentCommand;
     public DelegateCommand LoginMainContentCommand =>
            _loginMainContentCommand ?? (_loginMainContentCommand = new DelegateCommand(ExecuteLoginMainContentCommand));
    
     private DelegateCommand<object> _verityCommand;
     public DelegateCommand<object> VerityCommand =>
            _verityCommand ?? (_verityCommand = new DelegateCommand<object>(ExecuteVerityCommand));

     void ExecuteLoginMainContentCommand()
     {
         Navigate("LoginMainContent");
     }

     public CreateAccountViewModel(IRegionManager regionManager)
     {
         _regionManager = regionManager;
     }

     private void Navigate(string navigatePath)
     {
        if (navigatePath != null)
            _regionManager.RequestNavigate(RegionNames.LoginContentRegion, navigatePath);
     }

     public bool IsNavigationTarget(NavigationContext navigationContext)
     {
         return true;
     }

     public void OnNavigatedFrom(NavigationContext navigationContext)
     {
         MessageBox.Show("退出了CreateAccount");
     }

     public void OnNavigatedTo(NavigationContext navigationContext)
     {
         MessageBox.Show("從LoginMainContent導航到CreateAccount");
     }
    
     //注冊賬號
     void ExecuteVerityCommand(object parameter)
     {
         if (!VerityRegister(parameter))
         {
                return;
         }
         MessageBox.Show("注冊成功!");
         LoginMainContentCommand.Execute();
     }
    
     //導航前詢問
     public void ConfirmNavigationRequest(NavigationContext navigationContext, Action<bool> continuationCallback)
     {
         var result = false;
         if (MessageBox.Show("是否需要導航到LoginMainContent頁面?", "Naviagte?",MessageBoxButton.YesNo) ==MessageBoxResult.Yes)
         {
             result = true;
         }
         continuationCallback(result);
      }
 }

效果如下：

三.導航期間傳遞參數#

Prism提供NavigationParameters類以幫助指定和檢索導航參數，在導航期間，可以通過訪問以下方法來傳遞導航參數：

INavigationAware接口的IsNavigationTarget，OnNavigatedFrom和OnNavigatedTo方法中IsNavigationTarget，OnNavigatedFrom和OnNavigatedTo中形參NavigationContext對象的NavigationParameters屬性
IConfirmNavigationRequest接口的ConfirmNavigationRequest形參NavigationContext對象的NavigationParameters屬性
區域導航的INavigateAsync接口的RequestNavigate方法賦值給其形參navigationParameters
導航日志IRegionNavigationJournal接口CurrentEntry屬性的NavigationParameters類型的Parameters屬性(下面會介紹導航日志)

這里我們CreateAccount頁面注冊完用戶后詢問是否需要用當前注冊用戶來作為登錄LoginId，來演示傳遞導航參數，代碼如下：

CreateAccountViewModel.cs(修改代碼部分):

Copyprivate string _registeredLoginId;
public string RegisteredLoginId
{
    get { return _registeredLoginId; }
    set { SetProperty(ref _registeredLoginId, value); }
}

public bool IsUseRequest { get; set; }

void ExecuteVerityCommand(object parameter)
{
    if (!VerityRegister(parameter))
    {
        return;
    }
    this.IsUseRequest = true;
    MessageBox.Show("注冊成功!");
    LoginMainContentCommand.Execute();
}   

public void ConfirmNavigationRequest(NavigationContext navigationContext, Action<bool> continuationCallback)
{
    if (!string.IsNullOrEmpty(RegisteredLoginId) && this.IsUseRequest)
    {
         if (MessageBox.Show("是否需要用當前注冊的用戶登錄?", "Naviagte?", MessageBoxButton.YesNo) == MessageBoxResult.Yes)
         {
              navigationContext.Parameters.Add("loginId", RegisteredLoginId);
         }
    }
    continuationCallback(true);
}

LoginMainContentViewModel.cs(修改代碼部分):

Copypublic void OnNavigatedTo(NavigationContext navigationContext)
{
     MessageBox.Show("從CreateAccount導航到LoginMainContent");
            
     var loginId= navigationContext.Parameters["loginId"] as string;
     if (loginId!=null)
     {
         this.CurrentUser = new User() { LoginId=loginId};
     }
            
 }

效果如下：

四.導航日志#

Prism導航系統同樣的和WPF導航系統一樣，都支持導航日志，Prism是通過IRegionNavigationJournal接口來提供區域導航日志功能，

Copy    public interface IRegionNavigationJournal
    {
        bool CanGoBack { get; }

        bool CanGoForward { get; }

        IRegionNavigationJournalEntry CurrentEntry {get;}

        INavigateAsync NavigationTarget { get; set; }

        void GoBack();

        void GoForward();

        void RecordNavigation(IRegionNavigationJournalEntry entry, bool persistInHistory);

        void Clear();
    }

我們將在登錄界面接入導航日志功能,代碼如下:

LoginMainContent.xaml(前進箭頭代碼部分):

Copy<TextBlock Width="30" Height="30" HorizontalAlignment="Right" Text="" FontWeight="Bold" FontFamily="pack://application:,,,/PrismMetroSample.Infrastructure;Component/Assets/Fonts/#iconfont" FontSize="30" Margin="10" Visibility="{Binding IsCanExcute,Converter={StaticResource boolToVisibilityConverter}}">
      <i:Interaction.Triggers>
           <i:EventTrigger EventName="MouseLeftButtonDown">
                 <i:InvokeCommandAction Command="{Binding GoForwardCommand}"/>
            </i:EventTrigger>
      </i:Interaction.Triggers>
      <TextBlock.Style>
           <Style TargetType="TextBlock">
                <Style.Triggers>
                    <Trigger Property="IsMouseOver" Value="True">
                          <Setter Property="Background" Value="#F9F9F9"/>
                    </Trigger>
                 </Style.Triggers>
            </Style>
      </TextBlock.Style>
 </TextBlock>

BoolToVisibilityConverter.cs:

Copypublic class BoolToVisibilityConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
          if (value==null)
          {
              return DependencyProperty.UnsetValue;
          }
          var isCanExcute = (bool)value;
          if (isCanExcute)
          {
              return Visibility.Visible;
          }
          else
          {
              return Visibility.Hidden;
          }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
            throw new NotImplementedException();
    }
 }

LoginMainContentViewModel.cs(修改代碼部分):

CopyIRegionNavigationJournal _journal;

private DelegateCommand<PasswordBox> _loginCommand;
public DelegateCommand<PasswordBox> LoginCommand =>
            _loginCommand ?? (_loginCommand = new DelegateCommand<PasswordBox>(ExecuteLoginCommand, CanExecuteGoForwardCommand));

private DelegateCommand _goForwardCommand;
public DelegateCommand GoForwardCommand =>
            _goForwardCommand ?? (_goForwardCommand = new DelegateCommand(ExecuteGoForwardCommand));

private void ExecuteGoForwardCommand()
{
    _journal.GoForward();
}

private bool CanExecuteGoForwardCommand(PasswordBox passwordBox)
{
    this.IsCanExcute=_journal != null && _journal.CanGoForward;
    return true;
}

public void OnNavigatedTo(NavigationContext navigationContext)
{
     //MessageBox.Show("從CreateAccount導航到LoginMainContent");
     _journal = navigationContext.NavigationService.Journal;

     var loginId= navigationContext.Parameters["loginId"] as string;
     if (loginId!=null)
     {
                this.CurrentUser = new User() { LoginId=loginId};
     }
     LoginCommand.RaiseCanExecuteChanged();
}

CreateAccountViewModel.cs(修改代碼部分):

CopyIRegionNavigationJournal _journal;

private DelegateCommand _goBackCommand;
public DelegateCommand GoBackCommand =>
            _goBackCommand ?? (_goBackCommand = new DelegateCommand(ExecuteGoBackCommand));

void ExecuteGoBackCommand()
{
     _journal.GoBack();
}

 public void OnNavigatedTo(NavigationContext navigationContext)
 {
     //MessageBox.Show("從LoginMainContent導航到CreateAccount");
     _journal = navigationContext.NavigationService.Journal;
 }

效果如下：

選擇退出導航日志#

如果不打算將頁面在導航過程中不加入導航日志，例如LoginMainContent頁面，可以通過實現IJournalAware并從PersistInHistory（）返回false

Copy    public class LoginMainContentViewModel : IJournalAware
    {
        public bool PersistInHistory() => false;
    }

五.小結：#

prism的導航系統可以跟wpf導航并行使用，這是prism官方文檔也支持的，因為prism的導航系統是基于區域的，不依賴于wpf，不過更推薦于單獨使用prism的導航系統，因為在MVVM模式下更靈活，支持依賴注入,通過區域管理器能夠更好的管理視圖View,更能適應復雜應用程序需求，wpf導航系統不支持依賴注入模式，也依賴于Frame元素，而且在導航過程中也是容易強依賴View部分，下一篇將會講解Prism的對話框服務

.NET CORE(C#) WPF 抽屜式菜單

閱讀導航

本文背景
代碼實現
本文參考
源碼

1. 本文背景

使用簡單動畫實現抽屜式菜單

2. 代碼實現

使用 .NET CORE 3.1 創建名為 “AnimatedColorfulMenu” 的WPF模板項目，添加1個Nuget庫：MaterialDesignThemes，版本為最新預覽版3.1.0-ci948。

解決方案主要文件目錄組織結構：

AnimatedColorfulMenuApp.xamlMainWindow.xaml

2.1 引入樣式

文件【App.xaml】，在 StartupUri 中設置啟動的視圖【MainWindow.xaml】，并在【Application.Resources】節點增加 MaterialDesignThemes庫的樣式文件：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Indigo.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

2.2 演示窗體布局

文件【MainWindow.xaml】，代碼不多，主要看左側菜單，啟動時，菜單在顯示窗體左側-150位置；點擊展開菜單，使用簡單的動畫，慢慢呈現在顯示窗體左側，源碼如下：

<Window x:Class="AnimatedColorfulMenu.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

.NET CORE(C#) WPF 值得推薦的動畫菜單設計

閱讀導航

本文背景
代碼實現
本文參考
源碼

1. 本文背景

YouTube上老外的一個設計，站長覺得不錯，分享給大家作為參考，抽屜菜單的動畫做的非常不錯。

運行起始界面：

站長運行操作一遍，錄制了動畫大家看看：

2. 代碼實現

使用 .NET CORE 3.1 創建名為 “AnimatedMenu” 的WPF模板項目，添加1個Nuget庫：MaterialDesignThemes，版本為最新預覽版3.1.0-ci948。

解決方案主要文件目錄組織結構：

AnimatedMenu
App.xaml
MainWindow.xaml
MainWindow.xaml.cs

2.1 引入樣式

文件【App.xaml】，在 StartupUri 中設置啟動的視圖【MainWindow.xaml】，并在【Application.Resources】節點增加 MaterialDesignThemes庫的樣式文件：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Blue.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

2.2 演示窗體

文件【MainWindow.xaml】，布局代碼、動畫代碼都在此文件中，源碼如下：

簡單說明下：

"StackPanelMenu" 作為左側菜單容器，默認是顯示在窗體外，距離窗體左邊緣-250，點擊左上角菜單按鈕圖標可控制此容器的顯示與隱藏，注：菜單開關由兩個按鈕組成 "ButtonOpenMenu" 和 "ButtonCloseMenu"。
左側菜單項使用 "ListView" 進行布局，實際開發需要運用模板，使用MVVM做成動態菜單，方便擴展。
中間的5張演示照片，也和2類似。直接使用Grid進行的布局，實際上都需要做成模板。
抽屜菜單動畫見 Window.Resouces 中的動畫代碼，展開抽屜菜單動畫是 "OpenMenu"，左側菜單向右、向下移動，右側展示區域及個人信息概況界面同時也是向右、向下移動；關閉抽屜菜單動畫是 "CloseMenu"，動畫移動方向與展開時相反（說的是廢話），這段動畫代碼值得好好學習、復用。

文件【MainWindow.xaml.cs】，后臺關閉窗體、抽屜菜單按鈕切換、窗體移動等事件處理：

private void ButtonClose_Click(object sender, RoutedEventArgs e)
{
    Application.Current.Shutdown();
}

private void ButtonOpenMenu_Click(object sender, RoutedEventArgs e)
{
    ButtonOpenMenu.Visibility = Visibility.Collapsed;
    ButtonCloseMenu.Visibility = Visibility.Visible;
}

private void ButtonCloseMenu_Click(object sender, RoutedEventArgs e)
{
    ButtonOpenMenu.Visibility = Visibility.Visible;
    ButtonCloseMenu.Visibility = Visibility.Collapsed;
}

private void MoveWindow_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    DragMove();
}
