C# C# Collections Sets and Dictionaries Using Dictionaries

Cannot figure out task 1 of C# Collections Sets-and-dictionaries/using-dictionaries-- "Code the AddWord method..."

so far, I have--- using System.Collections.Generic;

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

    public void AddWord(string word)
    {
        List<string> output = new List<string>(output.Count);

        foreach(KeyValuePair<string, int> code in WordCount())
        {
            WordCount[int.Value] = int.Key;
        }
    }
}

}

and it is not working.

LexicalAnalysis.cs 
using System.Collections.Generic;

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

        public void AddWord(string word)
        {
            List<string> output = new List<string>(output.Count);

            foreach(KeyValuePair<string, int> code in WordCount())
            {
                WordCount[int.Value] = int.Key;
            }
        }
    }
}

:point_right: You've got a few issues to work on yet, here's a few hints:

  • List<string> output = new List<string>(output.Count) :point_left: You can't reference a variable while defining it
  • foreach(KeyValuePair<string, int> code in WordCount()) :point_left: You create code but never use it
  • also, WordCount is not a function (so no parentheses)
  • WordCount[int.Value] = int.Key :point_left: int is a type, not a variable
  • also, a dictionary would normally be indexed by a Key, not a Value
  • you'll probably want to test if the word is already in the dictionary
  • if word is not in the dictionary, you might add it with a value of 1
  • otherwise, you probably want to increment the current value

I am still stumped. I'm sorry.
