Current screen resolution in c#

Question

How can I get the current screen resolution of the screen where my form is?

I've already tried with primaryScreen but it does not work all times.

this.Size = new Size(Math.Min(width + 19, Screen.PrimaryScreen.WorkingArea.Width), Math.Min(height + dgvActualizar.ColumnHeadersHeight + 40, Screen.PrimaryScreen.WorkingArea.Height));

You are probably looking for the FromControl method:

Screen screenFormIsOn = Screen.FromControl(this);
var width = screenFormIsOn.WorkingArea.Width;
var height = screenFormIsOn.WorkingArea.Height;

Screen.FromControl should return the screen in which your form is loaded on.
