I am writing a graphics program where I have to make a circle go across a rectangle stop at the end of the rectangle and then turn and go back. How do I get it to go back?

Thank you

DrawEllipse method is used to draw ellipse or circle.

protected override void OnPaint(PaintEventArgs e)
{
Graphics g = e.Graphics ;
Pen pen = new Pen( Color.Black,3 );
Rectangle rect = new Rectangle(4, 4, 100, 100);
g.DrawEllipse( pen, rect );
}

u can draw rectangle as follows
