Comentarios

All containers, including the Package, Sequence, TaskHost, DtsEventHandler, ForLoop, and ForEachLoop, have an Executables property that contains the collection of executable objects processed by the run-time engine during execution of the container. The order of execution of the objects in the collection is determined by the PrecedenceConstraints inherited and implemented by the containers. You can add tasks to a package and set their properties graphically using the SSIS Designer, or programmatically using the run-time object model to build the package in Microsoft Visual Basic, Microsoft Visual C++, or C#. For more information, see Diseñar e implementar paquetes (Integration Services) and Agregar tareas a un flujo de control.
