Comentarios

La SoapAttributeAttribute clase pertenece a una familia de atributos que controla cómo serializa XmlSerializer o deserializa un objeto como XML SOAP codificado. El XML resultante se ajusta a la sección 5 del documento World Wide Web Consortium, Protocolo simple de acceso a objetos (SOAP) 1.1. Para obtener una lista completa de atributos similares, vea Atributos que controlan la serialización SOAP codificada.

Para serializar un objeto como un mensaje SOAP codificado, debe construir mediante XmlSerializer un XmlTypeMapping objeto creado con el ImportTypeMapping método de la SoapReflectionImporter clase .

Aplique a SoapAttributeAttribute un campo público para especificar que serializa XmlSerializer el campo como un atributo XML. Puede especificar un nombre alternativo del atributo estableciendo la AttributeName propiedad . DataType Establezca si el atributo debe tener un tipo de datos de lenguaje de definición de esquema XML (XSD) específico. Si el atributo pertenece a un espacio de nombres XML específico, establezca la Namespace propiedad .

Para obtener más información sobre el uso de atributos, vea Atributos.
