L’exemple de code suivant ajoute un FileSystemTask package et BulkInsertTask récupère les tâches d’une boucle à l’aide de la InnerObject méthode du type de TaskHost tâche.

Exemple de sortie :

Type Microsoft.SqlServer.Dts.Tasks.FileSystemTask.FileSystemTask

Type Microsoft.SqlServer.Dts.Tasks.BulkInsertTask.BulkInsertTask

Remarques

Vous pouvez récupérer l’instance de tâche spécifique en faisant passer le InnerObjectTaskHost type de tâche en tant que type de tâche. Ensuite, vous utilisez l’objet de la tâche pour accéder directement à ses méthodes et propriétés.
