Exemples

L'exemple de code suivant illustre l'utilisation du MessageContractAttribute pour contrôler la structure de l'enveloppe SOAP pour le message de demande et le message de réponse, et l'utilisation du MessageHeaderAttribute (pour créer un en-tête SOAP pour le message de réponse) et du MessageBodyMemberAttribute (pour spécifier les corps des messages de demande et de réponse).The following code example shows the use of the MessageContractAttribute to control the SOAP envelope structure for both the request message and the response message, and the use of both the MessageHeaderAttribute (to create a SOAP header for the response message) and the MessageBodyMemberAttribute (to specify the bodies of both the request and response message). L'exemple de code suivant contient un exemple de chaque type de message au moment de l'envoi.The code example contains an example of each message when sent.

Remarques

Utilisez l'attribut MessageBodyMemberAttribute pour spécifier qu'un membre de données est sérialisé dans le corps SOAP et contrôler certains éléments de sérialisation.Use the MessageBodyMemberAttribute attribute to specify that a data member is serialized into the SOAP body and to control some serialization items.

La propriété Order est utilisée pour spécifier l'ordre des éléments du corps dans les cas où l'ordre alphabétique par défaut ne convient pas.The Order property is used to specify the order of body parts in cases where the default alphabetical order is not appropriate.

Les autres propriétés sont héritées de la classe de base, System.ServiceModel.MessageContractMemberAttribute.The other properties are inherited from the base class, System.ServiceModel.MessageContractMemberAttribute.

Pour plus d’informations sur le contrôle de la sérialisation du contenu d’un corps SOAP sans modifier l’enveloppe SOAP par défaut proprement dite, consultez System.Runtime.Serialization.DataContractAttribute, Specifying Data Transfer in Service Contracts, et À l’aide de contrats de données.For more information about controlling the serialization of the contents of a SOAP body without modifying the default SOAP envelope itself, see System.Runtime.Serialization.DataContractAttribute, Specifying Data Transfer in Service Contracts, and Using Data Contracts.
