主窗体设计代码

<Window x:Class="LayoutPanels.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Menu" Height="400" Width="252"
    >
    <Grid>
      <StackPanel Margin="5" Button.Click="ButtonClick">
        <Button>SimpleStack</Button>
        <Button>SimpleWrap</Button>
        <Button>SimpleDock</Button>
        <Button>BasicDialogBox</Button>
        <Button>SimpleGrid</Button>
        <Button>LayoutRoundingTest</Button>
        <Button>SplitWindow</Button>
        <Button>DoubleSplitWindow</Button>
        <Button>SharedSizeGroup</Button>
        <Button>SimpleCanvas</Button>
        <Button>SimpleInkCanvas</Button>
        <Button>TheUniformGrid</Button>
        <Button>TextBoxColumn</Button>
        <Button>LocalizableText</Button>
        <Button>ModularContent</Button>
      </StackPanel>
        
    </Grid>
</Window>

关键代码为：

<StackPanel Margin="5" Button.Click="ButtonClick">

按钮实现代码：

private void ButtonClick(object sender, RoutedEventArgs e)
{
            // 获取当前按钮
            Button cmd = (Button)e.OriginalSource;
            // 创建由当前按钮命名的窗口实例
            Type type = this.GetType();
            Assembly assembly = type.Assembly;
            Window win = (Window)assembly.CreateInstance(type.Namespace + "." + cmd.Content);
            // 显示窗口
            win.Show();
}

记得添加引用：

using System.Reflection;
