我用WPF做了一个小计时器应用程序，我想把我的应用程序放在任务栏上，但是当我点击任务栏上的任何地方时，我的应用程序失去焦点，任务栏出现在我的应用程序的顶部，即使我在XAML代码中有Topmost=True。
我的应用程序的行为：
的数据
和Windows时钟应用程序的行为正是我想要的方式：🥺

有什么方法可以在我的WPF应用程序中实现此行为吗？

编辑：
我试过使用Window.Activate();，但它只适用于第一次点击任务栏，最重要的是，它不能很好地工作。它强制将焦点放在应用程序上，并且不允许在第一次点击时将焦点转移到另一个应用程序，这真的很糟糕。在下面的gif中，我试图展示它的行为。请注意，在第一次单击时，应用程序仍然在顶部，但在第二次单击时，应用程序再次位于任务栏后面。请注意，第一次单击时焦点没有转到Visual Studio上，但当我再次单击时，文本光标（插入符号）出现在我的代码上，焦点现在完全在Visual Studio上。Windows时钟应用程序不会发生这种情况，如果您在应用程序外部单击一次，焦点会立即转移到其他应用程序（尽管它仍然位于所有内容的顶部）。
