The following code example demonstrates how to use the Round and Truncate methods. This example is designed for use with a Windows Form. Paste this code into a form and call the RoundingAndTruncatingRectangles method when handling the form's Paint event, passing e as PaintEventArgs.
Private Sub RoundingAndTruncatingRectangles( _
ByVal e As PaintEventArgs)
' Construct a new RectangleF.
Dim myRectangleF As New RectangleF(30.6F, 30.7F, 40.8F, 100.9F)
' Call the Round method.
Dim roundedRectangle As Rectangle = Rectangle.Round(myRectangleF)
' Draw the rounded rectangle in red.
Dim redPen As New Pen(Color.Red, 4)
e.Graphics.DrawRectangle(redPen, roundedRectangle)
' Call the Truncate method.
Dim truncatedRectangle As Rectangle = _
Rectangle.Truncate(myRectangleF)
' Draw the truncated rectangle in white.
Dim whitePen As New Pen(Color.White, 4)
e.Graphics.DrawRectangle(whitePen, truncatedRectangle)
' Dispose of the custom pens.
redPen.Dispose()
whitePen.Dispose()
End Sub

// Draw the truncated rectangle in white.
