Question

Is there a built-in way to convert IEnumerator to IEnumerable?

Answer 1

As Jason Watts said -- no, not directly.

If you really want to, you could loop through the IEnumerator, putting the items into a List, and return that, but I'm guessing that's not what you're looking to do.

The basic reason you can't go that direction (IEnumerator to a IEnumerable) is that IEnumerable represents a set that can be enumerated, but IEnumerator is a specific enumeratation over a set of items -- you can't turn the specific instance back into the thing that created it.
