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）

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.
