c# - Get Layer of Window Relative to Other Windows -

In C # WPF, is there a way to position a window layer (i.e. z-index)? I have a program that grows new windows and I want to save the layers order.

So if I have three windows open, and window 1 is in front of window 2 and window 2 is in front of window 3, how can I get their position in relation to each other (or globally) Am I

You have to resort to Win32 interop :
