.NET CORE(C#) WPF 值得推薦的動畫菜單設計

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。

運行起始介面：

站長運行操作一遍，錄製了動畫大家看看：

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】，並在【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，註：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介面同時也是向右、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】，後台關閉窗體、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();
}

代碼已全部奉上...
