How can I get the active screen dimensions?

Question

What I am looking for is the equivalent of System.Windows.SystemParameters.WorkArea for the monitor that the window is currently on.

Clairification: The window in question is WPF, not WinForms.

Answer 1

Screen.FromControl, Screen.FromPoint and Screen.FromRectangle should help you with this. For example in WinForms it would be:

class MyForm : Form
{
  public Rectangle GetScreen()
  {
    return Screen.FromControl(this).Bounds;
  }
}

I don't know of an equivalent call for WPF. Therefore, you need to do something like this extension method.

static class ExtensionsForWPF
{
  public static System.Windows.Forms.Screen GetScreen(this Window window)
  {
    return System.Windows.Forms.Screen.FromHandle(new WindowInteropHelper(window).Handle);
  }
}

Answer 2

Add on to ffpf

Screen.FromControl(this).Bounds

Answer 3

You can use this:

System.Windows.SystemParameters.WorkArea

This is also usefull:

System.Windows.SystemParameters.PrimaryScreenWidth
System.Windows.SystemParameters.PrimaryScreenHeight

Answer 4

Also you may need:

SystemParameters.VirtualScreenWidth
SystemParameters.VirtualScreenHeight

to get the combined size of all monitors and not one in particular.
