How to determine a thread UI thread

Question

what is the simple way to know which thread is UI thread or the thread which create a control in a WinForm app?

When I opened window task manger, I found 8 threads for my winform application. So how many of them are UI threads.

generally, how many UI threads created by the winForm engine?

Answer 1

This may not answer your question since I don't know exactly what you are trying to accomplish but if Control.InvokeRequired is true then you are on the thread that created the control.
