本文实例讲述了C#实现控制Windows系统关机、重启和注销的方法。分享给大家供大家参考。具体分析如下：

使用.NET和C#.NET，我们可以对当前PC执行关机，重启，注销操作。

NET Framework中，有一个命名空间System.Diagnostics具有所需的类和方法，从当前PC上运行.NET应用程序来执行这些操作。
请使用下面的按钮来执行关机，重启和注销。

下面是一个winform程序

//SHUT DOWNprotected void btnShutDown_Click(object sender, EventArgs e){ Process.Start("shutdown.exe", "-s"); // By Default the Shutdown will take place after 30 Seconds //if you want to change the Delay try this one Process.Start("shutdown.exe","-s -t xx"); //Replace xx with Seconds example 10,20 etc}//RESTARTprotected void btnRestart_Click(object sender, EventArgs e){ Process.Start("shutdown.exe", "-r"); // By Default the Restart will take place after 30 Seconds //if you want to change the Delay try this one Process.Start("shutdown.exe","-r -t 10"); //Replace xx with Seconds example 10,20 etc}// LOG OFFprotected void btnLogOff_Click(object sender, EventArgs e){ Process.Start("shutdown.exe", "-l"); //This Code Will Directly Log Off the System Without warnings}

希望本文所述对大家的C#程序设计有所帮助。
