Answer 1

As Chris mentions in his comment on the original question, the sample code provided will return duplicates in list c (see his comment for details). Intersect will only return distinct values. To duplicate the behavior of the original sample code, try this:

var c = (from value in a
         where b.Contains(a)
         select a);
