true if the enumerator was successfully advanced to the next CachedDataItem; false if the enumerator has passed the end of the collection.

Exceptions
The collection was modified after the enumerator was created.
Remarks
After an enumerator is created or after Reset is called, an enumerator is positioned before the first element of the collection, and the first call to MoveNext moves the enumerator to the first element of the collection.
If MoveNext passes the end of the collection, the enumerator is positioned after the last element in the collection and MoveNext returns false. When the enumerator is at this position, subsequent calls to MoveNext also return false until Reset is called.
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 Reset throws an InvalidOperationException.
