The following example draws a line with an arrowhead at one end and a round cap at the other end. To run this example, Create a Windows Form and handle the form's Paint event. Paste the example code into the Paint event handler passing e as PaintEventArgs.

Pen pen = new Pen(Color.FromArgb(255, 0, 0, 255), 8);
pen.StartCap = LineCap.ArrowAnchor;
