Learn how to draw text on a Windows Form with the supplied code, examples, and additional descriptions. |
The following code example shows how to use the xref:System.Drawing.Graphics.DrawString%2A method of the xref:System.Drawing.Graphics to draw text on a form. Alternatively, you can use xref:System.Windows.Forms.TextRenderer for drawing text on a form. For more information, see How to: Draw Text with GDI.

You cannot call the xref:System.Drawing.Graphics.DrawString%2A method in the xref:System.Windows.Forms.Form.Load event handler. The drawn content will not be redrawn if the form is resized or obscured by another form. To make your content automatically repaint, you should override the xref:System.Windows.Forms.Control.OnPaint%2A method.
The following conditions may cause an exception:
- The Arial font is not installed.
- xref:System.Drawing.Graphics.DrawString%2A
- xref:System.Windows.Forms.TextRenderer.DrawText%2A
- xref:System.Drawing.StringFormat.FormatFlags%2A
- xref:System.Drawing.StringFormatFlags
- xref:System.Windows.Forms.TextFormatFlags
- xref:System.Windows.Forms.Control.OnPaint%2A
