How do I set the size of the visible area of a form, minus heading and borders?

Question

I would like to set my form to be exactly 300*300 excluding heading and borders.

If I use Size property, it does include these values.

Is there any way how to do it?

You have two options, as follows:

• To remove heading and borders from a Form, disable the Form's FormBorderStyle property.

• Set the interior of the form with the ClientSize property, as follows:

  this.ClientSize = new Size(300, 300);
