Exemples
L'exemple suivant illustre la création d'une instance de la classe SqlTrackingQueryOptions. Cet exemple est tiré de l'exemple du Kit de développement logiciel Workflow Monitor (SDK). Pour plus d’informations, consultez Exemple de moniteur de flux de travail.

Remarques
Le tableau suivant indique les valeurs initiales des propriétés d'une instance de la classe SqlTrackingQueryOptions.
Propriété | Valeur |
---|---|
StatusMaxDateTime | MaxValue. |
StatusMinDateTime | MinValue. |
TrackingDataItems | List<T> vide. |
WorkflowStatus | Référence Null (Nothing en Visual Basic). |
WorkflowType | Référence Null (Nothing en Visual Basic). |
Ces valeurs spécifient qu'un appel à SqlTrackingQuery.GetWorkflows doit retourner un objet SqlTrackingWorkflowInstance pour chaque instance de workflow qui a des données de suivi dans la base de données.
