Ejemplos

El siguiente ejemplo de código muestra el uso de MessageContractAttribute para controlar la estructura de envoltura SOAP para el mensaje de solicitud y el mensaje de respuesta, y el uso de MessageHeaderAttribute (para crear un encabezado SOAP para el mensaje de respuesta) y MessageBodyMemberAttribute (para especificar los cuerpos del mensaje de solicitud y respuesta). El ejemplo de código contiene un ejemplo de cada mensaje cuando se envía.

Comentarios

Utilice el atributo MessageBodyMemberAttribute para especificar que un miembro de datos se serializa en el cuerpo de SOAP y para controlar algunos elementos de serialización.

La propiedad Order se utiliza para especificar el orden de partes del cuerpo en casos donde el orden alfabético predeterminado no es adecuado.

Las otras propiedades se heredan de la clase base, System.ServiceModel.MessageContractMemberAttribute.

Para obtener más información sobre cómo controlar la serialización del contenido de un cuerpo SOAP sin modificar el propio sobre SOAP predeterminado, vea System.Runtime.Serialization.DataContractAttribute, Especificar transferencia de datos en contratos de servicio y Uso de contratos de datos.

Para más información, consulte Uso de contratos de mensaje.
