How to get monitor width and height in C# windows app?

Question

Hi My machine in windows-7 & Screen resolution is (1366 * 768) Highly recommended. float height = SystemInformation.VirtualScreen.Height; float width = SystemInformation.VirtualScreen.Width; double diagonal = Math.Sqrt(width * width + height * height); The above code I have used to get width and height of the screen to calculate diagonal in windows application. But the problem here is when I change the resolution width and height also gets change. So I need a piece of code that should read height and weight to calculate diagonal size. Please post solution for this post. Thanks in Advance.

I think the program can read the screen width and height are relevant to the resolution of the screen (that means only the software part and not the hardware part).

Hi Nitesh I have used System.Windows.Forms.Screen.PrimaryScreen.Bounds; And Even this code  Screen.PrimaryScreen.Bounds.Width & Screen.PrimaryScreen.Bounds.Height  returns height and width based on screen resolution.

Use Screen.PrimaryScreen.Bounds.Width and Screen.PrimaryScreen.Bounds.Height properties to get the actual width and height
