In your MainWindow Constructor add
在您的 MainWindow 构造函数中添加
this.Height = (System.Windows.SystemParameters.PrimaryScreenHeight * 0.25);
this.Width = (System.Windows.SystemParameters.PrimaryScreenWidth * 0.25);
Also don't set WindowState="Maximized" in your MainWindows.xaml otherwise it won't work. Hope this helps.
也不要在 MainWindows.xaml 中设置 WindowState="Maximized" 否则它将不起作用。希望这可以帮助。
