Esempio

L'esempio seguente è una classe proxy generata dall'utilità Wsdl.exe per chiamare un'utilità servizio Web XML tramite HTTP-POST. Il Wsdl.exe fornisce automaticamente i tipi corretti per ReturnFormatter e ParameterFormatter, oltre a specificare che la classe proxy eredita da HttpPostClientProtocol.

Commenti

Se un client del servizio Web XML chiama un metodo di servizio Web XML tramite HTTP-GET, ReturnFormatter deve essere impostato su XmlReturnReader e ParameterFormatter impostato su UrlParameterWriter. I client del servizio Web XML che richiamano un servizio Web XML tramite HTTP-POST devono essere impostati su ReturnFormatterXmlReturnReader e ParameterFormatter su HtmlFormParameterWriter.
