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). L'exemple de code suivant contient un exemple de chaque type de message au moment de l'envoi.
