想实现API函数ExitWindowsEx的功能，使用.NET framework提供的东东怎样去解决？（内空）

感谢您使用微软产品。

您可以使用Win32 API直接调用AdjustTokenPrivileges和ExitWindowsEx：

using System.Runtime.InteropServices;

//以下代码添加到类声明的后面：
[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;

private 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 );
}

使用方法:
DoExitWin( EWX_POWEROFF );

希望能对您有所帮助！
