Ｃ＃关机注销＝＝问题

调用API函数--注销计算机.
加入如下函数.还有加入命名空间.SyStem.Runtime.InteropServices;
[DllImport("user32.dll",EntryPoint="ExitWindowsEx",CharSet=CharSet.Ansi]
private static extern in ExitWindowsEx(int uFlags,int dwReserved);ExitWindowsEx(0,0);//注销.把它放在你想放在的事件中.即可完成功能.//关机.
System.Diagnostics.Process myProcess=new System.Diagnostics.Process();
myProcess.StartInfo.FileName="cmd.exe";
myProcess.StartInfo.UseShellExecute=false;
myProcess.StartInfo.RedirectStandardInput=true;
myProcess.StartInfo.RedirectStandardError=true;
myProcess.StartInfo.CreatNoWindow=true;
myProcess.Start();//
myProcess.StandardInput.WriteLine("shutdown -s -t 0");//重启一样:
System.Diagnostics.Process myProcess=new System.Diagnostics.Process();
myProcess.StartInfo.FileName="cmd.exe";
myProcess.StartInfo.UseShellExecute=false;
myProcess.StartInfo.RedirectStandardInput=true;
myProcess.StartInfo.RedirectStandardError=true;
myProcess.StartInfo.CreatNoWindow=true;
myProcess.Start();//
myProcess.StandardInput.WriteLine("shutdown -r -t 0");//这样可以让所以dos命令都能实现.经典吧.我个人认为.呵呵,
