如何在C# WPF中将命令绑定到MenuItem

public class MyCommand : ICommand
{
    public event EventHandler CanExecuteChanged;

    public bool CanExecute(object parameter)
    {
        // 在此处判断命令是否可执行的条件
        return true;
    }

    public void Execute(object parameter)
    {
        // 在此处定义命令执行的逻辑
    }
}

<Window x:Class="MyApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:MyApp"
        Title="My App" Height="450" Width="800">
    <Window.Resources>
        <local:MyCommand x:Key="MyCommand" />
    </Window.Resources>
    <Grid>
        <Menu>
            <MenuItem Header="File">
                <MenuItem Header="Open" Command="{StaticResource MyCommand}" />
                <MenuItem Header="Save" Command="{StaticResource MyCommand}" />
            </MenuItem>
        </Menu>
    </Grid>
</Window>

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = this;
    }

    public ICommand MyCommand { get; } = new MyCommand();
}
