DbEnumerator.MoveNext Method


Advances the enumerator to the next element of the collection.

 virtual bool MoveNext();
public bool MoveNext ();
abstract member MoveNext : unit -> bool
override this.MoveNext : unit -> bool
Public Function MoveNext () As Boolean



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



The collection was modified after the enumerator was created.


After an enumerator is created or after a call to Reset, an enumerator is positioned before the first element of the collection, and the first call to MoveNext moves the enumerator over the first element of the collection. After the end of the collection is passed, subsequent calls to MoveNext 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.
