The following code example creates a Pen and demonstrates the effects of setting the StartCap and EndCap properties on a Pen.

This example is designed to be used with Windows Forms. Paste the code into a form and call the ShowStartAndEndCaps method when handling the form's Paint event, passing e as PaintEventArgs.

private void Button3_Click(System.Object sender, System.EventArgs e)
{

    Graphics buttonGraphics = Button3.CreateGraphics();
    Pen myPen = new Pen(Color.ForestGreen, 4.0F);
    myPen.DashStyle = System.Drawing.Drawing2D.DashStyle.DashDotDot;

    Rectangle theRectangle = Button3.ClientRectangle;
    theRectangle.Inflate(-2, -2);
    buttonGraphics.DrawRectangle(myPen, theRectangle);
    buttonGraphics.Dispose();
    myPen.Dispose();
}
