Solution 1

A HashSet<string> is not meant to do searches on substrings.
A HashSet stores the hashcodes of its elements, and it provides a fast way to check wheter a specific element is already contained or not (fast because the search is done against hash codes, not values).
A List<string> could be more suitable.
