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：

• AnimatedColorfulMenu

• • App.xaml

  • MainWindow.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"xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"mc:Ignorable="d" Height="600" Width="1080" ResizeMode="NoResize" WindowStartupLocation="CenterScreen" WindowStyle="None"><Window.Resources><Storyboard x:Key="CloseMenu"><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)" Storyboard.TargetName="GridMenu"><EasingDoubleKeyFrame KeyTime="0" Value="150"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/></DoubleAnimationUsingKeyFrames><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="GridBackground"><EasingDoubleKeyFrame KeyTime="0" Value="1"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="0"/></DoubleAnimationUsingKeyFrames></Storyboard><Storyboard x:Key="OpenMenu"><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.X)" Storyboard.TargetName="GridMenu"><EasingDoubleKeyFrame KeyTime="0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="150"/></DoubleAnimationUsingKeyFrames><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Opacity)" Storyboard.TargetName="GridBackground"><EasingDoubleKeyFrame KeyTime="0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="1"/></DoubleAnimationUsingKeyFrames></Storyboard></Window.Resources><Window.Triggers><EventTrigger RoutedEvent="ButtonBase.Click" SourceName="ButtonClose"><BeginStoryboard x:Name="CloseMenu_BeginStoryboard" Storyboard="{StaticResource CloseMenu}"/></EventTrigger><EventTrigger RoutedEvent="ButtonBase.Click" SourceName="ButtonOpen"><BeginStoryboard Storyboard="{StaticResource OpenMenu}"/></EventTrigger></Window.Triggers><Grid><Grid x:Name="GridBackground" Background="#55313131" Opacity="0"/><Button x:Name="ButtonOpen" HorizontalAlignment="Left" VerticalAlignment="Top" Background="{x:Null}" BorderBrush="{x:Null}" Width="30" Height="30" Padding="0"><materialDesign:PackIcon Kind="Menu" Foreground="#FF313131"/></Button><!--左側抽屜菜單，默認在顯示窗體之外，點擊菜單圖標再通過簡單的動畫呈現出來--><Grid x:Name="GridMenu" Width="150" HorizontalAlignment="Left" Margin="-150 0 0 0" Background="White" RenderTransformOrigin="0.5,0.5"><Grid.RenderTransform><TransformGroup><ScaleTransform/><SkewTransform/><RotateTransform/><TranslateTransform/></TransformGroup></Grid.RenderTransform><StackPanel><Image Height="140" Source="https://img.dotnet9.com/logo-foot.png" Stretch="Fill"/><ListView Foreground="#FF313131" FontFamily="Champagne &amp; Limousines" FontSize="18"><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="Recycle" Width="20" Height="20" Foreground="Gray" Margin="5" VerticalAlignment="Center"/><TextBlock Text="回收" Margin="10"/></StackPanel></ListViewItem><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="HelpCircleOutline" Width="20" Height="20" Foreground="#FFF08033" Margin="5" VerticalAlignment="Center"/><TextBlock Text="幫助" Margin="10"/></StackPanel></ListViewItem><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="Lightbulb" Width="20" Height="20" Foreground="Green" Margin="5" VerticalAlignment="Center"/><TextBlock Text="發送反饋" Margin="10"/></StackPanel></ListViewItem><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="Heart" Width="20" Height="20" Foreground="#FFD41515" Margin="5" VerticalAlignment="Center"/><TextBlock Text="推薦" Margin="10"/></StackPanel></ListViewItem><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="StarCircle" Width="20" Height="20" Foreground="#FFE6A701" Margin="5" VerticalAlignment="Center"/><TextBlock Text="溢價認購" Margin="10"/></StackPanel></ListViewItem><ListViewItem Height="45" Padding="0"><StackPanel Orientation="Horizontal" Margin="10 0"><materialDesign:PackIcon Kind="Settings" Width="20" Height="20" Foreground="#FF0069C1" Margin="5" VerticalAlignment="Center"/><TextBlock Text="設置" Margin="10"/></StackPanel></ListViewItem></ListView></StackPanel><Button x:Name="ButtonClose" HorizontalAlignment="Right" VerticalAlignment="Top" Background="{x:Null}" Foreground="#CCC" BorderBrush="{x:Null}" Width="30" Height="30" Padding="0"><materialDesign:PackIcon Kind="Close"/></Button></Grid></Grid> </Window>
