关机理由已经屏蔽了,现在关机界面和xp一样,但就是关不了机。调用
DoExitWin(EWX_SHUTDOWN);
DoExitWin(EWX_POWEROFF);
都关不了机,代码如下,在网上找的。 [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)]

win2003关机需要管理员权限的。
如果ExitWindowsEx返回0,意思是失败,调用GetLastError可以得到错误。如果还不行,看看下面的文章是不是有帮助http://support.microsoft.com/kb/168796/en-us
internal const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege ";
多了个空格。
呵呵
是不是LookupPrivilegeValue就返回错误了。
