推荐答案

嗨 您可以在XAML中使用以下事件:

Hi You can use the following event in the XAML:

PreviewMouseDoubleClick="Window_PreviewMouseDoubleClick"

您不必将其放在窗口"上.您可以在顶部创建自己的标题栏，然后将事件添加到该控件中.因为将其添加到窗口使它可以在整个窗口中工作.

然后在事件中添加以下代码:

You don''t have to put it on the "Window". You can create your own title bar in the top and add the event to that control instead. Because adding it to the Window make it work all over the window.

Then add the following code in the event:

private void Window_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    if (this.WindowState == System.Windows.WindowState.Maximized)
        this.WindowState = System.Windows.WindowState.Minimized;
    else
        this.WindowState = System.Windows.WindowState.Maximized;
}

如果尚未最大化，则此方法将最大化；如果尚未最大化，则此方法将最小化.

希望它能对您有所帮助:-)

This method will maximize if not yet maximized, and minimize if maximized.

Hope it helped :-)
