[RESOLVED] string to list c#

[falahjomor]

I'm trying to convert a string to list<string> :

private List<string> removestopword(string input)
        {
             
             
             var Listtokens = from s in input.Split(' ')
                          where s.Length > 3 && !stopWordsList.Contains(s)
                          select s.ToList();


             return Listtokens;
        }

but it doesn't work . can anyone help? thanks
