西安软件开发实现锁屏代码
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();
