Property Value

A Type that deserializes the response from an XML Web service method. There is no default.

If the XML Web service client is invoking an XML Web service method using HTTP-GET, ReturnFormatter must be UrlParameterWriter, whereas a client using HTTP-POST must set ReturnFormatter to HtmlFormParameterWriter.

The example is a proxy class generated by the Wsdl.exe utility for an XML Web service client using HTTP-GET, setting ReturnFormatter to the required value of UrlParameterWriter.
