本文介绍了一个使用C#实现的系统关机程序。通过调用Windows API并设置必要的权限，该程序可以实现不同类型的系统关闭操作，如关机、重启等。

using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Runtime.InteropServices; namespace Dll { public class CloseCpu { public static void CpuReset() { CloseCpu cc = new CloseCpu(); cc.DoExitWin(2); } public static void CpuClose() { CloseCpu cc = new CloseCpu(); cc.DoExitWin(1); } /* ***************************** * * 关机方法--不使用系统API * * ***************************** */ 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); } [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; // 注销 internal const int EWX_SHUTDOWN = 0x00000001; //关机 internal const int EWX_REBOOT = 0x00000002; // 重起 internal const int EWX_FORCE = 0x00000004; internal const int EWX_POWEROFF = 0x00000008; internal const int EWX_FORCEIFHUNG = 0x00000010; } }
