1. 本文背景

YouTube上老外的一个设计，站长觉得不错，分享给大家作为参考，抽屉菜单的动画做的非常不错。

运行起始界面：

站长运行操作一遍，录制了动画大家看看：

2. 代码实现

使用 .NET CORE 3.1 创建名为 “AnimatedMenu” 的WPF模板项目，添加1个Nuget库：MaterialDesignThemes，版本为最新预览版3.1.0-ci948。

解决方案主要文件目录组织结构：

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

2.1 引入样式

文件【App.xaml】，在 StartupUri 中设置启动的视图【MainWindow.xaml】，并在【Application.Resources】节点增加 MaterialDesignThemes库的样式文件：

<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 演示窗体

文件【MainWindow.xaml】，布局代码、动画代码都在此文件中，源码如下：

<Window x:Class="AnimatedMenu.MainWindow"

简单说明下：

"StackPanelMenu" 作为左侧菜单容器，默认是显示在窗体外，距离窗体左边缘-250，点击左上角菜单按钮图标可控制此容器的显示与隐藏，注：菜单开关由两个按钮组成 "ButtonOpenMenu" 和 "ButtonCloseMenu"。
左侧菜单项使用 "ListView" 进行布局，实际开发需要运用模板，使用MVVM做成动态菜单，方便扩展。
中间的5张演示照片，也和2类似。直接使用Grid进行的布局，实际上都需要做成模板。
抽屉菜单动画见 Window.Resouces 中的动画代码，展开抽屉菜单动画是 "OpenMenu"，左侧菜单向右、向下移动，右侧展示区域及个人信息概况界面同时也是向右、向下移动；关闭抽屉菜单动画是 "CloseMenu"，动画移动方向与展开时相反（说的是废话），这段动画代码值得好好学习、复用。

文件【MainWindow.xaml.cs】，后台关闭窗体、抽屉菜单按钮切换、窗体移动等事件处理：

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();

}
