Beispiele

Im folgenden Beispiel wird eine Instanz einer Klasse mit dem Namen serialisiert Transportation , die ein Feld mit dem Namen enthält Vehicle .The following example serializes an instance of a class named Transportation that contains a field named Vehicle. Ein SoapElementAttribute wird auf das Feld angewendet.A SoapElementAttribute is applied to the field. Wenn das Feld serialisiert wird, lautet der Name des XML-Elements "Wheels" anstelle von "Vehicle".When the field is serialized, the XML element name is "Wheels" instead of "Vehicle". SerializeOverrideMit der-Methode wird ein erstellt SoapElementAttribute und die- SoapElement Eigenschaft eines-Objekts auf festgelegt SoapAttributes SoapElementAttribute .The SerializeOverride method creates a SoapElementAttribute and sets the SoapElement property of a SoapAttributes to the SoapElementAttribute. Der SoapAttributes wird einem hinzugefügt SoapAttributeOverrides , der zum Erstellen eines verwendet wird XmlTypeMapping .The SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlTypeMapping. Ein XmlSerializer wird mit erstellt XmlTypeMapping , und eine Instanz der- Transportation Klasse wird erneut serialisiert.An XmlSerializer is constructed with the XmlTypeMapping, and an instance of the Transportation class is again serialized. Da der SoapElementAttribute zum Überschreiben der Serialisierung verwendet wird, ist der generierte XML-Elementname 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- XmlTypeMapping Klasse wird verwendet, um ein Objekt als codiertes SOAP-XML zu serialisieren.The XmlTypeMapping class is used to serialize an object as encoded SOAP XML. Das resultierende XML entspricht Abschnitt 5 des World Wide Web Consortium Dokuments "Simple 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". Erstellen Sie einen, XmlTypeMapping indem Sie die- ImportTypeMapping Methode der-Klasse aufrufen SoapReflectionImporter .Create an XmlTypeMapping by calling the ImportTypeMapping method of the SoapReflectionImporter class. Verwenden XmlTypeMapping Sie, um eine Instanz der- XmlSerializer Klasse zu erstellen.Use the XmlTypeMapping to construct an instance of the XmlSerializer class. Um die Serialisierung zu steuern, verwenden Sie eines der Attribute, die unter Attribute zur Steuerung der Serialisierung von codiertem SOAPaufgeführt sind.To control the serialization, use one of the attributes listed in Attributes That Control Encoded SOAP Serialization.
