BUMMER! An item with the same key has already been added.
Code the AddWord method such that, WordCount will contain the number of times the AddWord method has been called with a given word.
For example, if AddWord is called twice with the word "rock" then WordCount["rock"] will be 2.
Please help...
using System.Collections.Generic;
namespace Treehouse.CodeChallenges
{
public class LexicalAnalysis
{
public Dictionary<string, int> WordCount = new Dictionary<string, int>();
public void AddWord(string word)
{
WordCount.Add(word, (WordCount.Count +1));
}
}
}

Your code should check to see if a word has already been added, and only add a new one if it's not already there. If it is already there, you can just modify the value.
