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.
