Developing a Custom Task

Integration Services uses tasks to perform units of work in support of the extraction, transformation, and loading of data. Integration Services includes a variety of tasks that perform the most frequently used actions, from executing an SQL statement to downloading a file from an FTP site. If the included tasks and supported actions do not completely meet your requirements, you can create a custom task.

To create a custom task, you have to create a class that inherits from the Task base class, apply the DtsTaskAttribute attribute to your new class, and override the important methods and properties of the base class, including the Execute method.

For working samples of custom tasks, see the Esempio di creazione di un'attività personalizzata per l'incremento di una variabile.
