Hey Anirudha,

The earlier answer is correct but just to add to it, you need to specify the type when you create the list. Arraylist does not have a distinct method by itself. Here is how you would do it,

List<string> foo = new List<string>();
foo.Add("sample");
foo.Add("sample");
...
IEnumerable bar = foo.Distinct();
