XNA: get screen width and height

Question

How to get the width and height of the whole screen in XNA?

Answer 1

It seems like this (just googled for “xna screen width”):

GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width 

Answer 2

Empirically, I found that in XNA 4.0 I need to use

 GraphicsDevice.Viewport.Width GraphicsDevice.Viewport.Height 

when starting windowed mode when i find

 GraphicsDevice.DisplayMode.Width GraphicsDevice.DisplayMode.Height 

gives me the resolution of the whole screen.

Hope this helps someone else.
