关机，重启，注销程序

namespace API测试

private void Form1_Load(object sender, EventArgs e)
{

}

//退出
private void button4_Click(object sender, EventArgs e)
{
Application.Exit();
}

const byte LOGOFF = 0; //
const byte SHUTDOWN = 1;
const byte REBOOT = 2;

[DllImportAttribute("User32.dll")]
static extern long ExitWindowsEx(byte uFlags, uint dwReason);

//关机
private void button3_Click(object sender, EventArgs e)
{
ExitWindowsEx(SHUTDOWN, 0);
}

//重启
private void button2_Click(object sender, EventArgs e)
{
ExitWindowsEx(REBOOT, 0);
}

//注销
private void button1_Click(object sender, EventArgs e)
{
ExitWindowsEx(LOGOFF, 0);
}
}
}


我这样写只有注销的功能实现了，而关机和重启这两个功能不能实现，请高手指教，能给出详细的代码吗，小弟非常感谢，我是C#的初学

者。如有什么好的资料或程序能否传到我的邮箱：[e-mail],QQ：402200280，本人非常想学好C#，不知从那方面，怎么去提高自

己的水平。若有高人指点就更好了！！！

System.Diagnostics.Process.Start("shutdown.exe","-s -t 0");
EWX_SHUTDONW,EWX_POWEROFF需要关机特权。
默认是不包含这些特权的

Process.Start("Shutdown.exe", " -s -t 0");//关机
Process.Start("shutdown.exe", " -r -t 0");//重启
