Solution 1

Generally you use the OnPaint or control_Paint methods to do your drawing. Then as @jhetal has suggested use the DrawLine method to draw the individual segments.

Are you the same person as asked C# openGL draw within a LOOP (for, while statement)[^], which I answered earlier?

OK, well the issue is basically the same. You iterate through all the points and draw lines between them, selecting different colours where needed.
