请从系统注销事件 [英] Get Log off event from system

问题描述

我做的这是用来清除临时文件，历史记录等，当用户注销的应用程序。所以，我怎么能知道，如果系统要注销（在C＃）？

I am doing an application which is used to clear the Temp files, history etc, when the user log off. So how can I know if the system is going to logoff (in C#)?

推荐答案

有一个在环保类属性的讲述，如果关机过程已经启动：

There is a property in Environment class that tells about if shutdown process has started:

Environment.HasShutDownStarted

但一些谷歌上搜索后，我发现，这可能是帮助你：

But after some googling I found out that this may be of help to you:

 using Microsoft.Win32;

 //during init of your application bind to this event  
 SystemEvents.SessionEnding += 
            new SessionEndingEventHandler(SystemEvents_SessionEnding);

 void SystemEvents_SessionEnding(object sender, SessionEndingEventArgs e)
 {
     if (Environment.HasShutdownStarted)
     {
         //Tackle Shutdown
     }
     else
     {
         //Tackle log off
     }
  }

但是，如果你只希望清除临时文件，然后我想关机区分或注销的任何后果不给你。

But if you only want to clear temp file then I think distinguishing between shutdown or log off is not of any consequence to you.
