Visual Studio 2005 下 ASP.net Web Service SOAP XML 节点的疑惑

?

[SoapDocumentMethod(

                  RequestNamespace = "http://www.contoso.com/Request",

                  RequestElementName = "RequestMessage",

                  ResponseNamespace = "http://www.contoso.com/Response",

                  ResponseElementName = "ResponseMessage")]

        [WebMethod(MessageName = "RequestMessage")]

        public Class2 HelloWorld(Class1 c1)

        {

            return new Class2();

        }

?

RequestElementName 和 [WebMethod(MessageName，有什么不同之处？

?

另外，Class1 c1,导致不能达到如下效果，该如何解决？

?
