用C#来执行关机命令呢，试试，没测过

string command = "shutdown -f -s -t 0";
Process newProcess = new Process();
newProcess.StartInfo.FileName = "cmd.exe";
newProcess.StartInfo.UseShellExecute = false;
newProcess.StartInfo.CreateNoWindow = true;
newProcess.StartInfo.RedirectStandardOutput = true;
newProcess.StartInfo.RedirectStandardInput = true;
newProcess.StartInfo.RedirectStandardError = true;
try
{
newProcess.Start();
newProcess.StandardInput.WriteLine(command);
newProcess.StandardInput.Close();
output = newProcess.StandardOutput.ReadToEnd();
newProcess.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}

抄别人的一段代码，没有测试，楼主试一下吧：



using System;

using System.Runtime.InteropServices;

class shoutdown

{

	[StructLayout(LayoutKind.Sequential, Pack = 1)]

	internal struct TokPriv1Luid

	{

		public int Count;

		public long Luid;

		public int Attr;

	}

	[DllImport("kernel32.dll", ExactSpelling = true)]

	internal static extern IntPtr GetCurrentProcess();

	[DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]

	internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);

	[DllImport("advapi32.dll", SetLastError = true)]

	internal static extern bool LookupPrivilegeValue(string host, string name, ref long pluid);

	[DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]

	internal static extern bool AdjustTokenPrivileges(IntPtr htok, bool disall,

	ref TokPriv1Luid newst, int len, IntPtr prev, IntPtr relen);

	[DllImport("user32.dll", ExactSpelling = true, SetLastError = true)]

	internal static extern bool ExitWindowsEx(int flg, int rea);

	internal const int SE_PRIVILEGE_ENABLED = 0x00000002;

	internal const int TOKEN_QUERY = 0x00000008;

	internal const int TOKEN_ADJUST_PRIVILEGES = 0x00000020;

	internal const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege";

	internal const int EWX_LOGOFF = 0x00000000;

	internal const int EWX_SHUTDOWN = 0x00000001;

	internal const int EWX_REBOOT = 0x00000002;

	internal const int EWX_FORCE = 0x00000004;

	internal const int EWX_POWEROFF = 0x00000008;

	internal const int EWX_FORCEIFHUNG = 0x00000010;

	private static void DoExitWin(int flg)

	{

		bool ok;

		TokPriv1Luid tp;

		IntPtr hproc = GetCurrentProcess();

		IntPtr htok = IntPtr.Zero;

		ok = OpenProcessToken(hproc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, ref htok);

		tp.Count = 1;

		tp.Luid = 0;

		tp.Attr = SE_PRIVILEGE_ENABLED;

		ok = LookupPrivilegeValue(null, SE_SHUTDOWN_NAME, ref tp.Luid);

		ok = AdjustTokenPrivileges(htok, false, ref tp, 0, IntPtr.Zero, IntPtr.Zero);

		ok = ExitWindowsEx(flg, 0);

	}

	public static void Main()

	{

		Console.WriteLine("正在关闭计算机……");

		// 修改 EWX_SHUTDOWN 或者 EWX_LOGOFF, EWX_REBOOT等实现不同得功能。 

		// 在XP下可以看到帮助信息，以得到不同得参数 

		// SHUTDOWN /? 

		DoExitWin(EWX_SHUTDOWN);

	}

}
