Questa raccolta può contenere istanze di classi che derivano da ServiceDescriptionFormatExtensiono istanze della XmlElement classe . In una classe derivata, ServiceDescriptionFormatExtension la classe consente agli utenti di definire elementi di estendibilità oltre a quelli definiti nella specifica WSDL (Web Services Description Language). Usa questi elementi nel tuo ServiceDescriptionFormatExtensionCollection se sai in anticipo il tipo di elemento di estendibilità che vuoi creare. Utilizzare un oggetto XmlElement quando non si conosce il formato di un elemento in anticipo.
