Answer 2

使用隧道事件，代码如下public Window1()
        {
            InitializeComponent();
            this.PreviewMouseLeftButtonDown += new MouseButtonEventHandler(Window1_PreviewMouseLeftButtonDown);
            this.PreviewKeyDown += new KeyEventHandler(Window1_PreviewKeyDown);
        }        void Window1_PreviewKeyDown(object sender, KeyEventArgs e)
        {
            e.Handled = true;
        }        void Window1_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            e.Handled = true;
        }
