true if the enumerator was successfully advanced to the next element; false if the enumerator has passed the end of the collection.
Implements
Exceptions
The collection was modified after the enumerator was created.
Remarks
After an enumerator is created, the enumerator is positioned before the first element in the collection, and the first call to MoveNext advances 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.
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 IEnumerator.Reset throws an InvalidOperationException.
