请参考活动窗口在WPF？ [英] Refer to active Window in WPF?

问题描述

如何可以参考我在C＃WPF应用程序的活动窗口，使用类似的ActiveFor​​m属性的WinForms？

How can I refer to active Window of WPF application in C#, using something like ActiveForm property in WinForms?

推荐答案

一可能的方法是扫描应用程序打开的窗口的列表并检查哪个其中一人有 IsActive = TRUE ：

One possible way would be to scan the list of open windows in the application and check which one of them has IsActive = true:

Application.Current.Windows.OfType<Window>().SingleOrDefault(x => x.IsActive);

不知道是否有可能不止一个活动窗口，举个例子，有一个模式对话框显示在这种情况下，对话的所有者和对话本身可能是活性

Not sure if there may be more than one active window if, for example, there's a modal dialog showing, in which case, the owner of the dialog and the dialog itself might be active.
