XNA: get screen's width and height
Solution 1:
Empirically I've found that in XNA 4.0 I need to use
GraphicsDevice.Viewport.Width
GraphicsDevice.Viewport.Height
when running windowed mode, as I find
GraphicsDevice.DisplayMode.Width
GraphicsDevice.DisplayMode.Height
gives me the resolution of the entire screen.
Hopefully this helps someone else out.
Solution 2:
This seems to be it (just googled for "xna screen width height" myself):
GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Height
GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width
Solution 3:
GraphicsDevice.Viewport.Bounds - this returns Rectangle2D and it has parameters Width and Height.
