You just posted your code, please give more info so we can help. What's the problem with your code? What were the result it gave you? What's the result you want to achive? What things did you try?

You could write your property starting on line 40 in one line. It is called an auto-implemented property. It goes like this: public int counter { get; set; }
Don't know exactly what your problem is, could you tell us a bit more?

Try this

public void Circles() {
    Graphics g = panel1.CreateGraphics;
    if (counter > 0) {
        using (Pen redPen = new Pen(Color.Red)) {
            g.DrawEllipse(redPen, panel1.Width / 2, panel1. Height / 2, 75, 75);
        }
    }

    if (counter > 1) {
        using (Pen bluePen = new Pen(Color.Blue)) {
            g.DrawEllipse(bluePen, panel1.Width / 2, panel1. Height / 2, 50, 50);
        }
    }

    if (counter > 2) {
        using (yellowPen = new Pen(Color.Yellow)) {
            g.DrawEllipse(yellowPen, panel1.Width / 2, panel1. Height / 2, 80, 80);
        }
    }

    if (counter > 3) {
        using (greenPen = new Pen(Color.Green)) {
            g.DrawEllipse(greenPen, panel1.Width / 2, panel1. Height / 2, 100, 100);
        }
    }
}
