Advances the enumerator to the next element of the SortedSet<T> collection.
Assembly: System (in System.dll)
The collection was modified after the enumerator was created.
After an enumerator is created, the enumerator is positioned before the first element in the collection, and the first call to the method advances the enumerator to the first element of the collection.
If passes the end of the collection, the enumerator is positioned after the last element in the collection and returns false. When the enumerator is at this position, subsequent calls to 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.
