How can i get the width and height of the screen in xna?

Question

So in my 2d tower defense game I need to get the resolution of the screen for use in my scaling matrix. However I can't find a way that works. I've tried:

_graphics.GraphicsDevice.Viewport.Width

and

GraphicsAdapter.DefaultAdapter.CurrentDisplayMode.Width

//It always crashes the game
_graphics.PreferredBackBufferWidth
//Also crashes

THis is my exact code

screenscalex = (float) *whatever i put here* / 1366f;

Thank you!

"*However I can't find a way that works.*" Which ways have you tried? [XNA: get screen's width and height](http://stackoverflow.com/questions/1377524/xna-get-screens-width-and-height)? — Jonathan Lonowski, Feb 11 '14 at 01:38
have you tried `graphics.PresentationParameters.PreferredBackBufferWidth`? (and height) — davidsbro, Feb 11 '14 at 01:40
It goes back to the start screen and the game stops debugging — Detinator10, Feb 11 '14 at 02:13

Make sure you are doing these checks after initialize is called. the graphics device must be initialized before checking these items.
