Does LINQ work with IEnumerable?

Question

I have a class that implements IEnumerable, but doesn\'t implement IEnumerable. I can\'t change this class, and I can\'t use another class

IEnumerable objects = ...;
IEnumerable strings = objects.Cast();

Or if you don't know what type it contains you can always do:

IEnumerable
