Exemples

L'exemple de code suivant montre comment créer un TrackingProfileSerializer à l'aide du constructeur TrackingProfileSerializer pour sérialiser un TrackingProfile. Le code utilise également la méthode Serialize.

Cet exemple de code fait partie de l'exemple du Kit de développement logiciel Query using SQLTrackingService (SDK) et provient du fichier Program.cs. Pour plus d’informations, consultez Interroger à l’aide de SQLTrackingService.

Remarques

La sérialisation fait référence au processus de création d'un document XML bien formé à partir d'un TrackingProfile. Serialize utilise le Schema de modèle de suivi pour sérialiser le modèle de suivi. profile doit être un TrackingProfile valide qui contient au moins un trackpoint valide. La validation du modèle de suivi est effectuée pendant la sérialisation et, si le modèle de suivi n’est pas valide, une ArgumentException est levée. Vous pouvez intercepter cette exception et examiner sa propriété de message pour déterminer la cause de l’erreur de validation. Si des exceptions non prises en charge se produisent lors de la sérialisation du modèle de suivi, l'instance de workflow pour laquelle le modèle de suivi a été demandé est arrêtée.
