HashSet can be used when you dont want set having duplicate values. For example - List dupInts = new List {1,3,4,5,3,3,6}; HashSet noDupInts = new HashSet(dupInts); When this will run - noDupInts will have as {1,3,4,5,6}

HashSet noDupInts = new HashSet(dupInts);

HashSet Is used when you want to have a collection with unique elements. HashSet stores list of unique elements and won't allow duplicates in it.
