How do I find out the size of the entire desktop? Not the "working area" and not the "screen resolution", both of which refer to only one screen. I want to find out the total width and height of the virtual desktop of which each monitor is showing only a part.

You have two options:

  1. PresentationFramework.dll

    SystemParameters.VirtualScreenWidth   
SystemParameters.VirtualScreenHeight

  2. System.Windows.Forms.dll

    SystemInformation.VirtualScreen.Width   
SystemInformation.VirtualScreen.Height

Use the first option if you developing a WPF application.
