C#关机代码的实现是如何的呢?我们经常会碰到这样的需求,那么在这方面我们是如何实现的呢?让我们还是看看实际的代码操作,希望对于你C#关机代码的开发有所启示。
C#关机代码实现实例:(支持Win XP下的关机)
- using System.Runtime.InteropServices;
- //C#关机代码
- [StructLayout(LayoutKind.Sequential, Pack=1)]
- internal struct TokPriv1Luid
- {
- public int Count;
- public long Luid;
- public int Attr;
- }
- //C#关机代码
- [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;
- //C#关机代码
- 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 );
- }
- public void Reboot()
- {
- DoExitWin( EWX_REBOOT );
- }
- //C#关机代码
- //点击按钮,执行关机事件
- private void button1_Click(object sender, System.EventArgs e)
- {
- DoExitWin(1);
- }
C#关机代码的实现过程就向你介绍到这里,希望对你了解和学习C#关机代码有所帮助。
