wpf 窗体双击放大和缩小

给窗体鼠标按下事件绑定处理方法

this.MouseDown += MainWindow_MouseDown;

在鼠标按下事件处理方法中实现拖拽和放大缩小

private void MainWindow_MouseDown(object sender, MouseButtonEventArgs e) { // 按下拖动 if (e.LeftButton == MouseButtonState.Pressed) { this.DragMove(); } // 双击放大 if (e.ClickCount == 2 && e.ChangedButton == MouseButton.Left) { this.WindowState = this.WindowState == WindowState.Maximized ? WindowState.Normal : WindowState.Maximized; } }
