You could write your own extension method for string like:

static class StringExtension
        {
            public static bool ContainsWord(this string s, string word)
            {
                string[] ar = s.Split(' ');

                foreach (string str in ar)
                {
                    if (str.ToLower() == word.ToLower())
                        return true;
                }
                return false;
            }
        }
