In Using Dictionaries, I have a question for the second challenge.

using System.Collections.Generic;

namespace Treehouse.CodeChallenges
{
    public class LexicalAnalysis
    {
        public Dictionary<string, int> WordCount = new Dictionary<string, int>();

        public void AddWord(string word)
        {
            int count = 0;
            if(WordCount.ContainsKey(word))
            {
                WordCount[word] = WordCount[word] + 1; 
            }
            else if(!(WordCount.ContainsKey(word)))
            { 
                WordCount.Add(word,count+1);
            }
        }

        public Dictionary<string, int> WordsWithCountGreaterThan (int counter){
            Dictionary<string, int> WordsWithGreaterCounter = new Dictionary<string,int>();

            foreach(KeyValuePair<string,int> searchedWord in WordCount){

                if(WordCount[searchedWord.Value] > counter){
                WordsWithGreaterCounter.Add(searchedWord.Key,searchedWord.Value);
               }
            }
            return WordsWithGreaterCounter;
        }
    }
}
