The XmlTypeMapping class is used to serialize an object as encoded SOAP XML. The resulting XML conforms to section 5 of the World Wide Web Consortium (www.w3.org) document, "Simple Object Access Protocol (SOAP) 1.1". Create an XmlTypeMapping by calling the ImportTypeMapping method of the SoapReflectionImporter class. Use the XmlTypeMapping to construct an instance of the XmlSerializer class. To control the serialization, use one of the attributes listed in [<topic://cpconAttributesThatControlSOAPEncodedSerialization>].

The following example serializes an instance of a class named Transportation that contains a field named Vehicle. A SoapElementAttribute is applied to the field. When the field is serialized, the XML element name is "Wheels" instead of "Vehicle". The SerializeOverride method creates a SoapElementAttribute and sets the SoapElement property of a SoapAttributes to the SoapElementAttribute. The SoapAttributes is added to a SoapAttributeOverrides that is used to create an XmlTypeMapping. An XmlSerializer is constructed with the XmlTypeMapping, and an instance of the Transportation class is again serialized. Because the SoapElementAttribute is used to override the serialization, the generated XML element name is now "Truck" instead of "Wheels".
