Hinweise

Die SoapAttributeAttribute-Klasse gehört zu einer Familie von Attributen, die das Serialisieren bzw. Deserialisieren eines Objekts als codiertes SOAP XML durch XmlSerializer steuern. Das resultierende XML entspricht Abschnitt 5 des Dokuments "Simple Object Access Protocol (SOAP) 1.1" des World Wide Web Consortium (www.w3.org). Eine vollständige Liste ähnlicher Attribute finden Sie unter Attribute für die Steuerung der Serialisierung von codiertem SOAP.

Um ein Objekt als codierte SOAP-Meldung zu serialisieren, müssen Sie den XmlSerializer mithilfe einer XmlTypeMapping erstellen, die mit der ImportTypeMapping-Methode der SoapReflectionImporter-Klasse erstellt wurde.

Wenden Sie das SoapAttributeAttribute auf ein öffentliches Feld an, um anzugeben, dass der XmlSerializer das Feld als XML-Attribut serialisiert. Sie können einen alternativen Namen für das Attribut angeben, indem Sie die AttributeName-Eigenschaft festlegen. Legen Sie DataType fest, wenn dem Attribut ein spezifischer XSD (XML Schema Definition language)-Datentyp zugewiesen werden muss. Wenn das Attribut zu einem bestimmten XML-Namespace gehört, legen Sie die Namespace-Eigenschaft fest.

Weitere Informationen über das Verwenden von Attributen finden Sie unter Erweitern von Metadaten mithilfe von Attributen.

Hinweis

Sie können das Wort SoapAttribute anstelle des längeren SoapAttributeAttribute im Code verwenden.

Im folgenden Beispiel wird eine Klasse serialisiert, die mehrere Felder enthält, denen ein SoapAttributeAttribute zugewiesen wird.
