Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie die Round - Truncate Methode und die-Methode verwendet werden.The following code example demonstrates how to use the Round and Truncate methods. Dieses Beispiel ist für die Verwendung mit einem Windows Form konzipiert.This example is designed for use with a Windows Form. Fügen Sie diesen Code in ein Formular ein, RoundingAndTruncatingRectangles und nennen Sie die-Methode Paint , wenn Sie das PaintEventArgs-Ereignis des Formulars behandeln, indem e Sie alsPaste this code into a form and call the RoundingAndTruncatingRectangles method when handling the form's Paint event, passing e as PaintEventArgs.
