Méthodes
Nom | Description | |
---|---|---|
CanUpdate | A Boolean that indicates if the new package XML can update the old package XML. | |
Equals | Determines whether two object instances are equal. (hérité de DtsObject.) | |
Finalize | (hérité de Object.) | |
GetEnumerator | Returns a managed enumerator, IEnumerator, for iterating over the collections. | |
GetHashCode | Returns the hash code for this instance. (hérité de DtsObject.) | |
GetType | (hérité de Object.) | |
InitializeForEachEnumerator | Initializes the properties associated with the task. This method is called by the runtime and is not used in code. | |
MemberwiseClone | (hérité de Object.) | |
ToString | (hérité de Object.) | |
Update | This method updates the old package XML with the new package XML if CanUpdate is set to true. | |
Validate | Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. |

Notes
This class provides the abstract (MustInherit in Visual Basic) base class for enumerators over the foreach loop collection. Inherits from DtsObject and IDTSForEachEnumerator.
