1.实现效果

自定义菜单切换动画

2.业务场景

菜单切换动画

3.编码实现

3.1 添加Nuget库

使用 .Net Core 3.1 创建名为“CustomMenu”的WPF解决方案，添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors。

MaterialDesign控件库

3.2 工程结构

只修改了App.xaml（添加MD控件样式）和MainWindow.xaml（主窗口实现效果）。

3.3 App.xaml引入MD控件样式

<Application x:Class="CustomMenu.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:CustomMenu"
             StartupUri="MainWindow.xaml">
    <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.MergedDictionaries>
            <!--PRIMARY-->
            <SolidColorBrush x:Key="PrimaryHueLightBrush" Color="#349FDA"/>
            <SolidColorBrush x:Key="PrimaryHueLightForegroundBrush" Color="#FF333333"/>
            <SolidColorBrush x:Key="PrimaryHueMidBrush" Color="#0288d1"/>
            <SolidColorBrush x:Key="PrimaryHueMidForegroundBrush" Color="#FFDDDDDD"/>
            <SolidColorBrush x:Key="PrimaryHueDarkBrush" Color="#015f92"/>
            <SolidColorBrush x:Key="PrimaryHueDarkForegroundBrush" Color="#FFFFFF"/>
            <!--ACCENT-->
            <SolidColorBrush x:Key="SecondaryAccentBrush" Color="#FF50F350"/>
            <SolidColorBrush x:Key="SecondaryAccentForegroundBrush" Color="#FFFFFF"/>
        </ResourceDictionary>
    </Application.Resources>
</Application>

3.4 主窗体 MainWindow.xaml

添加菜单、设置菜单项切换动画等：

<Window x:Class="CustomMenu.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:local="clr-namespace:CustomMenu"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        mc:Ignorable="d"
        Title="MainWindow" Height="600" Width="1080" Background="#FF292929" ResizeMode="NoResize" WindowStyle="None"
        WindowStartupLocation="CenterScreen">

    <Window.Resources>
        <Storyboard x:Key="Move0">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)"
                                           Storyboard.TargetName="ellipse">
                <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="0">
                    <EasingDoubleKeyFrame.EasingFunction>

                    </EasingDoubleKeyFrame.EasingFunction>
                </EasingDoubleKeyFrame>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>

        <Storyboard x:Key="Move1">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[3].(TranslateTransform.Y)"
                                           Storyboard.TargetName="ellipse">
                <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="40">

                    </EasingDoubleKeyFrame.EasingFunction>

        </Storyboard>

        <Storyboard x:Key="Move2">

                    </EasingDoubleKeyFrame.EasingFunction>
                </EasingDoubleKeyFrame>
