Public Class XmlTypeMapping
	Inherits XmlMapping

NameDescription
System_CAPS_pubpropertyElementName

This API supports the product infrastructure and is not intended to be used directly from your code. Get the name of the mapped element.(Inherited from XmlMapping.)

System_CAPS_pubpropertyNamespace

This API supports the product infrastructure and is not intended to be used directly from your code. Gets the namespace of the mapped element.(Inherited from XmlMapping.)

System_CAPS_pubpropertyTypeFullName

The fully qualified type name that includes the namespace (or namespaces) and type.

System_CAPS_pubpropertyTypeName

Gets the type name of the mapped object.

System_CAPS_pubpropertyXsdElementName

This API supports the product infrastructure and is not intended to be used directly from your code. Gets the name of the XSD element of the mapping.(Inherited from XmlMapping.)

System_CAPS_pubpropertyXsdTypeName

Gets the XML element name of the mapped object.

System_CAPS_pubpropertyXsdTypeNamespace

Gets the XML namespace of the mapped object.

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodSetKey(String)

This API supports the product infrastructure and is not intended to be used directly from your code. Sets the key used to look up the mapping.(Inherited from XmlMapping.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

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 Attributes That Control Encoded SOAP Serialization.

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".
