I have this code that draws a Rectangle ( Im trying to remake the MS Paint )

 case "Rectangle":
               if (tempDraw != null)
                {
                    tempDraw = (Bitmap)snapshot.Clone();
                    Graphics g = Graphics.FromImage(tempDraw);
                    Pen myPen = new Pen(foreColor, lineWidth);
                    g.DrawRectangle(myPen, x1, y1, x2-x1, y2-y1);
                    myPen.Dispose();
                    e.Graphics.DrawImageUnscaled(tempDraw, 0, 0);
                    g.Dispose();
                }

But what if I want to draw a circle, what will change?

g.DrawRectangle(myPen, x1, y1, x2-x1, y2-y1);

     private void DrawEllipseRectangle(PaintEventArgs e)
        {
            Pen p = new Pen(Color.Black, 3);
            Rectangle r = new Rectangle(100, 100, 100, 100);
            e.Graphics.DrawEllipse(p, r);
        }
     private void Form1_Paint(object sender, PaintEventArgs e)

PictureBox circle = new PictureBox();
circle.Paint += new PaintEventHandler(circle_Paint);        

void circle_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawEllipse(Pens.Red, 0, 0, 30, 30);
        }
