GetScoreForWord

        private static int GetScoreForWord(string Word, Dictionary<char, int> TileDictionary)
        {
            int Score = 0;
            for (int Count = 0; Count < Word.Length; Count++)
            {
                Score = Score + TileDictionary[Word[Count]];
            }
            if (Word.Length > 7)
            {
                Score = Score + 20;
            }
            else if (Word.Length > 5)
            {
                Score = Score + 5;
            }
            return Score;
        }

The above section of code will use a 'for' loop in order to calculate the score, by taking the word length into account and giving an integer value based upon the length of the word. The loop will only run until the count is equal to or greater than the length of the word.
