Adds an System.Xml.Serialization.XmlElementAttribute declaration to a method return value that corresponds to a <part> element of a non-SOAP message definition in a Web Services Description Language (WSDL) document.
- metadata
- The collection of System.CodeDom.CodeAttributeDeclaration objects for the generated type to which the method adds an attribute declaration.
- mapping
- The internal .NET Framework type mapping information for an XML schema element.
- ns
- The XML namespace of the SOAP message part for which the type mapping information in the member parameter has been generated.
The Web Services Description Language tool (Wsdl.exe) uses this method when a WSDL document specifies the .NET Framework's non-SOAP implementations of Web services using the HTTP-GET and HTTP-POST operations.
