您可以通过调用API函数ExitWindowEx来实现关机，示例如下： [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 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 ); } 您只需在程序中调用DoExitWin( EWX_POWEROFF );即可实现关机操作。
