As we discussed, the DrawString method of the Graphics class can be used to draw text on a graphics surface. The DrawString method takes a string, font, brush and starting point.

Listing 5.8 creates three different fonts and draws text on a form using the DrawString method. Each DrawString method uses a different color and font to draw the string.
