关机程序乍就不关机呢
参考了网是上的c#   关机程序
其实地方就几行

using   System.Runtime.InteropServices;       //命名空间


[DllImport( "user32.dll ",   ExactSpelling=true,   SetLastError=true)   ]    
internal   static   extern   bool   ExitWindowsEx(   int   flg,   int   rea   );   //调用api

如果click关机按钮就
ExitWindowsEx(1,0);       //关，关，关
 
可是为什么就是不关机呢？
是我的代码错了还是和我的操作系统有关系（我的是window   2003   server）


------解决方案--------------------
03 需要特权MSDN这样说：“
To shut down or restart the system, the calling process must use the AdjustTokenPrivileges function to enable the SE_SHUTDOWN_NAME privilege. For more information, see Running with Special Privileges.
