如何在wpf的上下文菜单中创建绑定项目的选择？

<Window.Resources>
    <ContextMenu x:Key="MyContextMenu">
        <!-- 在这里定义菜单项 -->
        <MenuItem Header="菜单项1" Command="{Binding Command1}" />
        <MenuItem Header="菜单项2" Command="{Binding Command2}" />
        <!-- 其他菜单项 -->
    </ContextMenu>
</Window.Resources>

<Button Content="右键点击我">
    <Button.ContextMenu>
        <StaticResource ResourceKey="MyContextMenu" />
    </Button.ContextMenu>
</Button>

<MenuItem Header="菜单项1" Command="{Binding Command1}" />

public class MyViewModel
{
    public ICommand Command1 { get; set; }
    public ICommand Command2 { get; set; }

    public MyViewModel()
    {
        Command1 = new RelayCommand(ExecuteCommand1);
        Command2 = new RelayCommand(ExecuteCommand2);
    }

    private void ExecuteCommand1()
    {
        // 处理菜单项1的逻辑
    }

    private void ExecuteCommand2()
    {
        // 处理菜单项2的逻辑
    }
}
