Is it possible to get a screenshot of a window that is not on the top, i.e. if it is partially hidden by another window, without bringing it to the top?

See Question&Answers more detail:osUnfortunately, it's not trivial to take a screen-shot in C# at all, you can create a graphics object based on the current window or viewport and capture that, but its not what you're asking for.

might help, but you'd have to do this with Interop code anyway.
I dare say that it's not a common thing that is supported as really, one program has no business knowing what's being displayed in another program; it's potentially a nasty exploit.
