Parametri

  • CreationName
    Tipo: System.String
    A String that contains the unique identifier of the old package.

Valore restituito

Tipo: System.Boolean
A Boolean that indicates if the new package XML can update the old XML.

Osservazioni

The Integration Services run-time engine calls CanUpdate on new objects and passes in the GUID of the old object. If the new object can update the old object, the old object is passed to the new one through the Update method, where the XML is changed.

By default, all extensible objects implement CanUpdate to return false and implement the Update method to do nothing on the XML it is given in its parameters.
