구현
예
The following code example creates a ForEachLoop, creates a SMO enumerator and hosts it in a ForEachEnumeratorHost, where it is then added as the ForEachEnumerator in the ForEachLoop. Returning a ForEachSMOEnumerator, a SMODataFileEnumerator is created as a System.Collections.IEnumerator and iterated over using MoveNext and Current. After the index has passed the end of the collection, the Reset is used to reset the iterator.
