本文介绍了一个使用C#编写的简单程序，该程序能够利用Windows API调用获得关闭、重启计算机的权限。通过调整参数可以实现不同的操作，如注销、重启、强制关机等。


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);
      }
}
