How to draw a circle on form1 and fill it ?

Question

private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawEllipse(new Pen(Color.Red, 1), 10, 10, 10, 10);
        }

If I change the Pen width from 1 to 3 or to 10 it will be more wide but not filled.

I want to draw like a point filled so I can change it's size but keep it filled not empty circle.

Answer 1

Use FillEllipse :

 e.Graphics.FillEllipse(new SolidBrush(System.Drawing.Color.Red), 10, 10, 10, 10);
