最简单的方式是贯彻落实 ButtonClick 事件处理程序，并调用 window.close（）的方法。但如何通过做到这一点命令绑定？

The easiest way is to implement ButtonClick event handler and invoke Window.Close() method. But how to do this through a Command binding?

推荐答案

我觉得在现实世界中的场景一个简单的点击处理程序可能比过于复杂基于命令的系统更好，但你可以做这样的事情：

I think that in real world scenarios a simple click handler is probably better than over-complicated command-based systems but you can do something like that:

using RelayCommand from this article http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

public class MyCommands
{
    public static readonly ICommand CloseCommand =
        new RelayCommand( o => ((Window)o).Close() );
}

<Button Content="Close Window"
        Command="{X:Static local:MyCommands.CloseCommand}"
        CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}"/>
