推荐答案

这可以使用类Microsoft.Win32.SystemEvents完成.请参阅:
http://msdn.microsoft.com/en-us/library/microsoft.win32. systemevents.aspx [ ^ ].

注意静态事件Microsoft.Win32.SystemEvents.SessionEnding和Microsoft.Win32.SystemEvents.SessionEnding.您向其中的任何一个添加事件句柄，检查结束原因，该原因在事件参数中传递给您，并在会话实际结束之前执行操作.有趣且重要的是，如果SessionEnding您甚至可以取消结尾，这将有效地延迟关闭或重新启动，直到用户允许通过忽略您的应用程序或检查是否可以安全结束该命令来强制关闭或重新启动它为止会议.请参阅:
http://msdn.microsoft.com/en-us/library/microsoft. win32.systemevents.sessionending.aspx [ ^ ]，

This can be done using the class Microsoft.Win32.SystemEvents. Please see:
http://msdn.microsoft.com/en-us/library/microsoft.win32.systemevents.aspx[^].

Pay attention for the static events Microsoft.Win32.SystemEvents.SessionEnding and Microsoft.Win32.SystemEvents.SessionEnding. You add a event handle to any of them, check up the reason of ending, which is passed to you in event arguments, and perform the action before the session actually ends. Interestingly and importantly, in case if SessionEnding you can even cancel the ending, which will effectively delay shutdown or restart until the user allows to forcefully shutdown or restart it either by ignoring your application or checking if it''s safe to end the session. Please see:
http://msdn.microsoft.com/en-us/library/microsoft.win32.systemevents.sessionending.aspx[^],
