How to get the size of a Winforms Form titlebar height?

Question

So if it\'s toolwindow or a minimizable form, I want to be able to get its height programmatically.

Is this possible? If so how?

Answer 1

In my case, I had to change the height of the form so that it was just below one of the controls, I noticed that

  int titleHeight = this.Height - screenRectangle.Height;

returns 39 while the accepted answer:

  int titleHeight =  screenRectangle.Top - this.Top;

returns 31

maybe because of form's bottom border.
