Ejemplos

El siguiente MyWebService servicio Web XML define uno SoapHeader de tipo MyHeader.The following MyWebService XML Web service defines one SoapHeader of type MyHeader. El Hello método de servicios Web XML requiere que el cliente invoque el método de servicios Web SoapHeaderXML con este.The Hello XML Web service method requires the client to invoke the XML Web service method with this SoapHeader. El Hello servicio Web XML también detecta los encabezados SOAP que no sean MyHeader.The Hello XML Web service also catches any SOAP headers other than MyHeader.

Los pasos básicos para recibir y procesar un encabezado SOAP son:The basic steps to receiving and processing a SOAP header are:

  1. Cree una clase que derive de SoapHeader que represente los datos pasados en el encabezado SOAP.Create a class deriving from SoapHeader representing the data passed in the SOAP header.

  2. Agregue un miembro a la clase de servicio Web XML o a la clase de proxy de cliente de servicios Web XML del tipo creado en el paso 1.Add a member to the XML Web service class or XML Web service client proxy class of the type created in step 1.

  3. Aplique al método de servicios Web XML o al método correspondiente de la clase de proxy, especificando el miembro creado en el paso 2 en MemberName la propiedad. SoapHeaderAttributeApply a SoapHeaderAttribute to the XML Web service method or the corresponding method in the proxy class, specifying the member created in step 2 in the MemberName property.

  4. Dentro del método de servicios Web XML o del código de cliente del servicio Web MemberName XML, tenga acceso a la propiedad para procesar los datos enviados en el encabezado SOAP.Within the XML Web service method or XML Web service client code, access the MemberName property to process the data sent in the SOAP header.

Para obtener más información, vea MemberName la propiedad.For more details, see the MemberName property.
