Beispiele

Im folgende Beispiel wird eine Instanz einer Klasse namens serialisiert Transportation , enthält ein Feld namens Vehicle.The following example serializes an instance of a class named Transportation that contains a field named Vehicle. Ein SoapElementAttribute auf das Feld angewendet wird.A SoapElementAttribute is applied to the field. Wenn das Feld serialisiert wird, wird der XML-Elementname "Wheels" anstelle von "Vehicle".When the field is serialized, the XML element name is "Wheels" instead of "Vehicle". Die SerializeOverride -Methode erstellt eine SoapElementAttribute und legt sie fest der SoapElement Eigenschaft eine SoapAttributes auf die SoapElementAttribute.The SerializeOverride method creates a SoapElementAttribute and sets the SoapElement property of a SoapAttributes to the SoapElementAttribute. Die SoapAttributes hinzugefügt wird eine SoapAttributeOverrides , dient zum Erstellen einer XmlTypeMapping.The SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlTypeMapping. Ein XmlSerializer wird erstellt, mit der XmlTypeMapping, und eine Instanz von der Transportation -Klasse erneut serialisiert wird.An XmlSerializer is constructed with the XmlTypeMapping, and an instance of the Transportation class is again serialized. Da die SoapElementAttribute wird verwendet, um die Serialisierung zu überschreiben, der Name des generierten XML-Elements ist jetzt "Truck" anstelle von "Wheels".Because the SoapElementAttribute is used to override the serialization, the generated XML element name is now "Truck" instead of "Wheels".

Hinweise

Die SoapElementAttribute Klasse gehört zu einer Familie der Attribute, die steuert, wie die XmlSerializer Serialisieren oder Deserialisieren eines Objekts als codiertes SOAP XML.The SoapElementAttribute class belongs to a family of attributes that controls how the XmlSerializer serializes or deserializes an object as encoded SOAP XML. Das resultierende XML entspricht Abschnitt 5 des World Wide Web Consortium-Dokuments, einfache Object Access Protocol (SOAP) 1.1.The resulting XML conforms to section 5 of the World Wide Web Consortium document, Simple Object Access Protocol (SOAP) 1.1. Eine vollständige Liste ähnlicher Attribute, finden Sie unter Attributes, die Control Encoded SOAP Serialization.For a complete list of similar attributes, see Attributes That Control Encoded SOAP Serialization.

Zum Serialisieren eines Objekts als codiertes SOAP-Nachricht müssen Sie erstellen die XmlSerializer mithilfe einer XmlTypeMapping erstellt, mit der ImportTypeMapping -Methode der der SoapReflectionImporter Klasse.To serialize an object as an encoded SOAP message, you must construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

Anwenden der SoapElementAttribute zu einem öffentlichen Feld leiten die XmlSerializer , das Feld als codiertes SOAP XML-Element serialisieren.Apply the SoapElementAttribute to a public field to direct the XmlSerializer to serialize the field as an encoded SOAP XML element.
