How to determine the screen width/height using C#

Question

I want to set the width & height of a Window dynamically based on the user screens maximum width/height. How can I determine this programmatically?

Answer 1

If you want the specific dimensions of the monitor your program is running on (if someone is running more than one monitor) you could also use:

var helper = new WindowInteropHelper(this); //this being the wpf form 
var currentScreen = Screen.FromHandle(helper.Handle);

This will return a screen object referencing the monitor the program is running on. From there you can use the currentScreen.Bounds.Width / Height property (for the full size) or the currentScreen.WorkingArea.Width / Height (minus task bar, etc.) depending on what you want.
