[整理]一个对计算机进行控制的类(c#)不断更新中
  
  整理了几个实用的对计算机管理的C#代码,放在一个类中,方便使用
  目前整理了如下方法:
  public static void PowerOff()关机
  public static void LogOff()注销
  public static void CloseMonitor(IntPtr handle)关闭显示器
  public static void OpenMonitor(IntPtr handle)打开显示器
  
  
  public class MyControl
  
  
  
  
  {
  [StructLayout(LayoutKind.Sequential, Pack = 1)]
  private struct TokPriv1Luid
  {
  public int Count;
  public long Luid;
  public int Attr;
  } [DllImport("kernel32.dll", ExactSpelling = true)]
  private static extern IntPtr GetCurrentProcess();
  [DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
  private static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);
  [DllImport("advapi32.dll", SetLastError = true)]
  private static extern bool LookupPrivilegeValue(string host, string name, ref long pluid);
  [DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
  private static extern bool AdjustTokenPrivileges(IntPtr htok, bool disall, ref TokPriv1Luid newst, int len, IntPtr prev, IntPtr relen);
  [DllImport("user32.dll", ExactSpelling = true, SetLastError = true)]
  private static extern bool ExitWindowsEx(int DoFlag, int rea);
  [DllImport("user32.dll")]
  public static extern IntPtr SendMessage(IntPtr hWnd, uint msg, uint wParam, int lParam);
  private const int SE_PRIVILEGE_ENABLED = 0x00000002 private const int TOKEN_QUERY = 0x00000008 private const int TOKEN_ADJUST_PRIVILEGES = 0x00000020 private const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege" private const int EWX_LOGOFF = 0x00000000 private const int EWX_SHUTDOWN = 0x00000001 private const int EWX_REBOOT = 0x00000002 private const int EWX_FORCE = 0x00000004 private const int EWX_POWEROFF = 0x00000008 private const int EWX_FORCEIFHUNG = 0x00000010
  
  
  
  private const uint WM_SYSCOMMAND = 0x0112 private const uint SC_MONITORPOWER = 0xF170 private static void DoExitWin(int DoFlag)
  {
  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(DoFlag, 0);
  } public static void Reboot()
  {
  DoExitWin(EWX_FORCE | EWX_REBOOT);
  } public static void PowerOff()
  {
  DoExitWin(EWX_FORCE | EWX_POWEROFF);
  } public static void LogOff()
  {
  DoExitWin(EWX_FORCE | EWX_LOGOFF);
  } public static void CloseMonitor(IntPtr handle)
  {
  SendMessage(handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2);
  } public static void OpenMonitor(IntPtr handle)
  {
  SendMessage(handle, WM_SYSCOMMAND, SC_MONITORPOWER, -1);
  }
  
  }
