Hinweise

LogicalMethodInfo wird hauptsächlich von einer SOAP-Erweiterung zum Abfragen der Details der XML-Webdienstmethode verwendet, mit der die SOAP-Erweiterung gemäß ihrer Konfiguration ausgeführt wird. In Abhängigkeit von der Konfiguration der SOAP-Erweiterung kann diese Details über die XML-Webdienstmethode in der GetInitializer-Methode der SoapExtension ermitteln, die eine LogicalMethodInfo annimmt. Die LogicalMethodInfo stellt Details wie die Parameter der XML-Webdienstmethode bereit, indem sie auf die Parameters-Eigenschaft und alle unter Verwendung der GetCustomAttributes-Eigenschaft auf die XML-Webdienstmethode angewendeten benutzerdefinierten Attribute zugreift.

Weitere Informationen über SOAP-Erweiterungen finden Sie in der SoapExtension-Klasse oder unter Änderung von SOAP-Nachrichten mithilfe von SOAP-Erweiterungen.
