  • C#实现自动锁屏+关屏 枫

    新近找到了windows锁屏API:LockWorkStation

      于是乎把之前的关屏API整合了一下,弄了个可以选择自动锁屏+关屏的东东。

      如下代码片段:

      public Form1( bool aLock ) {

      if (aLock) {

      //锁屏+关屏

      LockWorkStation();

      SendMessage( this.Handle, (uint)0x0112, (IntPtr)0xF170, (IntPtr)2 );

      }

      else {

      //禁止鼠标键盘动作+关屏

      BlockInput( true );

      System.Threading.Thread.Sleep( 10 );

      SendMessage( this.Handle, (uint)0x0112, (IntPtr)0xF170, (IntPtr)2 );

      BlockInput( false );

      }

      this.Close();

      //Application.Exit();

      Environment.Exit( 0 );

      }

      //关屏

      [DllImport( "user32.dll", CharSet = CharSet.Auto )]

      static extern IntPtr SendMessage( IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam );

      //禁止鼠标键盘动作

      [return: MarshalAs( UnmanagedType.Bool )]

      [DllImport( "user32.dll", CharSet = CharSet.Auto, ExactSpelling = true )]

      public static extern bool BlockInput( [In, MarshalAs( UnmanagedType.Bool )] bool fBlockIt );

      //锁屏

      [DllImport( "user32.dll" )]

      public static extern bool LockWorkStation();

      需要指出的是,在退出程序时使用Environment.Exit( 0 );而非Application.Exit();否则会出错哦~~提示类似:“***遇到错误,需要关闭”。

      还有就是修改一下Main:

      static void Main(string[] args) {

      //Application.EnableVisualStyles();

      //Application.SetCompatibleTextRenderingDefault( false );

      if (args == null || args.Length == 0) {

      //禁止鼠标键盘动作+关屏

      Application.Run( new Form1( false ) );

      }

      else {

      //锁屏+关屏

      Application.Run( new Form1( true ) );

      }

      }

      ..

      如此即可大功告成了。。。

      之所以要禁用鼠标键盘,是为了关屏成功。。。~~~废话。。。

      新建个快捷方式,加个参数,即可锁屏。
