Enumerable.Range implementation

Question

What is the precise implementation of Enumerable.Range in .Net; preferable .Net 4? Is it a yielded for-loop? A custom implementation (IEnumerable, IEnumerator) or?<

Answer 1

You can use Reflector to see the implementation for yourself. It checks arguments and throws exception at the time of calling, so the Range method itself is not an iterator method. It calls another method which is an iterator method. It's not OK to post the exact code due to license restrictions.
