C# WPF抽屉效果实现（C# WPF Material Design UI: Navigation Drawer & PopUp Menu）

时间如流水，只能流去不流回！

点赞再看，养成习惯，这是您给我创作的动力！

本文 Dotnet9 https://dotnet9.com 已收录，站长乐于分享dotnet相关技术，比如Winform、WPF、ASP.NET Core等，亦有C++桌面相关的Qt Quick和Qt Widgets等，只分享自己熟悉的、自己会的。

一、先看效果：

二、本文背景

有网友给站长Dotnet9留言：“WPF中能否实现UWP中SplitView效果，即抽屉效果吗？” Dotnet9记得国外开源C# WPF控件库MaterialDesignInXaml中有这种效果，可以查看本站写的推荐文章：MaterialDesignInXaml控件介绍，站长也是个喜欢码砖的人，对代码是很感兴趣的，遂Google了一个YouTube视频敲出本文实现的代码，希望对他和您有用。

三、代码实现

站长使用.Net Core 3.1创建的WPF工程，创建PopUpAndNav解决方案后，需要添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors。

添加Material两个库

工程比较简单，主要就是演示窗口MainWindow：

解决方案结构

代码不多，我就全部贴上代码吧。

添加MaterialDesignInXaml样式：App.xaml

 <Application x:Class="PopUpAndNav.App"
              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
              xmlns:local="clr-namespace:PopUpAndNav"
              StartupUri="MainWindow.xaml">
     <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>
 </Application>

App.xaml

演示窗口MainWindow.xaml代码，使用简单的自定义窗口，看效果图，有右上角的标题栏菜单及左上角的抽屉菜单：

         </Grid>
     </Grid>
 </Window>

MainWindow.xaml

后台MainWindow.xaml.cs，主要是处理窗体关闭事件及抽屉菜单的展开与折叠：

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using System.Threading.Tasks;
 using System.Windows;
 using System.Windows.Controls;
 using System.Windows.Data;
 using System.Windows.Documents;
 using System.Windows.Input;
 using System.Windows.Media;
 using System.Windows.Media.Imaging;
 using System.Windows.Navigation;
 using System.Windows.Shapes;

 namespace PopUpAndNav
 {
     /// <summary>
     /// Interaction logic for MainWindow.xaml
     /// </summary>
     public partial class MainWindow : Window
     {
         public MainWindow()
         {
             InitializeComponent();
         }

         private void ButtonPopUpLogout_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 GridTitle_MouseDown(object sender, MouseButtonEventArgs e)
         {
             DragMove();
         }
     }
 }

MainWindow.xaml.cs
