# How to: Draw a Line with Line Caps
You can draw the start or end of a line in one of several shapes called line caps. GDI+ supports several line caps, such as round, square, diamond, and arrowhead.  
  
## Example  
 You can specify line caps for the start of a line (start cap), the end of a line (end cap), or the dashes of a dashed line (dash cap).  
  
 The following example draws a line with an arrowhead at one end and a round cap at the other end. The illustration shows the resulting line:

## Compiling the Code  
  
- Create a Windows Form and handle the form's <xref:System.Windows.Forms.Control.Paint> event. Paste the example code into the <xref:System.Windows.Forms.Control.Paint> event handler passing `e` as <xref:System.Windows.Forms.PaintEventArgs>.
