Exemples

L'exemple suivant illustre différentes façons permettant d'instancier un objet ServiceDescription.The following example illustrates various ways to instantiate a ServiceDescription object.

Remarques

Les informations contenues dans ServiceDescription le sont utilisées par le système Windows Communication Foundation (WCF) pour créer les composants d’exécution du service.The information contained in the ServiceDescription is used by the Windows Communication Foundation (WCF) system to building the run-time components for the service.

Utilisez cette méthode lors de l'ajout de comportements personnalisés pour étendre ServiceHost.Use this method when adding custom behaviors to extend ServiceHost. Par programme, vous devez Add(T) le comportement de service personnalisé aux Behaviors avant d'appeler la méthode Open sur l'objet ServiceHost.Programmatically, you must Add(T) the custom service behavior to the Behaviors prior to when you call the Open method on the ServiceHost object.

Les GetService(Object) méthodes GetService(Type) et sont disponibles pour réfléchir les comportements à l’aide du modèle de programmation Windows Communication Foundation (WCF) ServiceHostBase lors du remplacement de par votre propre mécanisme d’hébergement.The GetService(Object) and GetService(Type) methods are available to reflect on behaviors using the Windows Communication Foundation (WCF) programming model when replacing ServiceHostBase with you own hosting mechanism.

Exportez les métadonnées liées à un point de terminaison de service via ServiceEndpoint comme paramètre de ExportEndpoint(ServiceEndpoint).Export metadata about a service endpoint by passing ServiceEndpoint as a parameter to ExportEndpoint(ServiceEndpoint). Après avoir appelé cette méthode ou l'une des autres méthodes d'exportation fournies par WsdlExporter, utilisez la propriété GeneratedWsdlDocuments pour retourner la collection d'objets ServiceDescription.After calling this method, or one of the other export methods provided by WsdlExporter, use the GeneratedWsdlDocuments property to return the collection of ServiceDescription objects.
