Osservazioni

The Execute method is inherited by task hosts and other objects from the Executable abstract class, through the DtsContainer class, and allows the inheriting objects to be run by the run-time engine. The Execute method inherited by the individual objects is not commonly used in code, and it is recommended that you call the Execute method if you need to run any of the tasks or containers in the package. However, the Execute method is available on individual objects should you find a unique circumstance where it is needed.

The Execute method is mainly used when you inherit and override it during creation of a custom task. For more information about how to override the Execute method, see Scrittura del codice di un'attività personalizzata.

The Execute method calls the Validate method implicitly before the package runs. All the tasks in the package are reviewed for appropriate settings during validation, and all the objects in the package are reviewed, including the package, containers, and other components in the package.

If no problems are encountered in the validation phase that would cause the package to fail, the package object proceeds to call the Execute method for each task and object in the package.

Pass nullriferimento Null (Nothing in Visual Basic). for the transaction parameter when the TransactionOption property is false. If the TransactionOption property is true, you can pass null in the transaction parameter to indicate that the container supports transactions but does not participate.
