推荐答案

您无需执行任何操作.键盘Alt + F4或您描述的单击将关闭窗口.如果它是主窗口，它将带您从入口点方法返回，并最终终止应用程序.

System.Windows.Application.Shutdown的使用在此处进行了详细说明:
http://msdn.microsoft.com/en-us/library/ms597013.aspx [ ^ ].

通过将处理程序添加到为键盘事件定义的事件对象的调用列表中，或者通过覆盖受保护的虚拟方法System.Windows.UIElement.OnKeyDown，System.Windows.UIElement.OnKeyUp，System.Windows.UIElement.OnPreviewKeyDown或System.Windows.UIElement.OnPreviewKeyUp，可以处理键盘事件.请参阅:
http://msdn.microsoft.com/en-us/library/system.windows. uielement.onkeydown [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.onkeyup [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.onpreviewkeydown [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.onpreviewkeyup [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.keydown [^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.keyup [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.previewkeydown [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.windows. uielement.previewkeyup [ ^ ]，

您可能需要更好地了解WPF中输入事件和附加事件的工作方式.请参阅:

You don''t need to do anything. Keyboard Alt+F4 or the click you described will close the window. If it is a main window, it will bring you to the return from the entry-point method and ultimately the termination of the application.

The use of System.Windows.Application.Shutdown is described in detail here:
http://msdn.microsoft.com/en-us/library/ms597013.aspx[^].

The keyboard events are handled by adding the handlers to the invocation lists of the event objects defined for keyboard events or, alternatively, by overriding the protected virtual methods System.Windows.UIElement.OnKeyDown, System.Windows.UIElement.OnKeyUp, System.Windows.UIElement.OnPreviewKeyDown or System.Windows.UIElement.OnPreviewKeyUp. Please see:
http://msdn.microsoft.com/en-us/library/system.windows.uielement.onkeydown[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.onkeyup[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.onpreviewkeydown[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.onpreviewkeyup[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.keydown[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.keyup[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.previewkeydown[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement.previewkeyup[^],
http://msdn.microsoft.com/en-us/library/system.windows.uielement[^].

You may need to understand better how input and attached events work in WPF. Please see:
