Sets the enumerator to its initial position, which is before the first element in the collection.
Assembly : Microsoft.SqlServer.ManagedDTS (en Microsoft.SqlServer.ManagedDTS.dll)
An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying, or deleting elements, the enumerator is irrecoverably invalidated and the next call to MoveNext or throws an InvalidOperationException.
All calls to must result in the same state for the enumerator. The preferred implementation is to move the enumerator to the beginning of the collection, before the first element. This invalidates the enumerator if the collection has been modified since the enumerator was created, which is consistent with MoveNext and Current.
