重启使用WMI，网上代码很多。估计注销也可以使用WMI。关机使用调用API的类如下： using System; using System.Runtime.InteropServices ; namespace OffComputer { /// <summary> /// Offcomputer 的摘要说明。 /// 关闭计算机 /// </summary> public class Offcomputer { [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; public Offcomputer() { // // TODO: 在此处添加构造函数逻辑 // } public static void ShutDown(int i) //i=0 ShutDown i=1 Reboot { if (i == 0) { DoExitWin(EWX_SHUTDOWN + EWX_FORCE); } else if (i == 1) { DoExitWin(EWX_REBOOT + EWX_FORCE); } } 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); } } }
