在WPF中,如何实现ICommandSource以使我的自定义控制能力能够使用来自xaml的命令？

public class MyCustomControl : Button, ICommandSource
{
    public static readonly DependencyProperty CommandProperty =
        DependencyProperty.Register("Command", typeof(ICommand), typeof(MyCustomControl));

    public static readonly DependencyProperty CommandParameterProperty =
        DependencyProperty.Register("CommandParameter", typeof(object), typeof(MyCustomControl));

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public object CommandParameter
    {
        get { return GetValue(CommandParameterProperty); }
        set { SetValue(CommandParameterProperty, value); }
    }

    protected override void OnClick()
    {
        base.OnClick();

        if (Command != null && Command.CanExecute(CommandParameter))
        {
            Command.Execute(CommandParameter);
        }
    }
}

<Window xmlns:local="clr-namespace:YourNamespace">
    <Window.Resources>
        <local:YourCommand x:Key="YourCommand" />
    </Window.Resources>
    <Grid>
        <local:MyCustomControl Command="{StaticResource YourCommand}" CommandParameter="YourParameter" />
    </Grid>
</Window>
