whats wrong with this code help pliz

Challenge Task 2 of 2

Create a method named WordsWithCountGreaterThan that takes an integer as a parameter. The method should return a dictionary of all of the words that have a count greater than the parameter passed in. The dictionary should contain the word and the word's count.

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)
        {
              if (WordCount.ContainsKey(word))
            {
                WordCount[word]++;
            }
            else
            {
                WordCount.Add(word, 1);
            }

            public void WordsWithCountGreaterThan (int num){
            if (WordCount > num) {
                WordCount.Add(num);
            }

            return WordCount;
        }
    }
}

To build on what Steven Parker has already stated, here is a small walkthrough of the code challenge.

The following will have a mix of code from the challenge and pseudocode. 

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

    public void AddWord(string word)
    {
        //TODO Check if word is in dictionary, if word exists add 1 to word count.
        // if WordCount contains word
            //WordCount[Key]++ This will increment the value of the key because the value is an integer
        // If word does not exist, add word to dictionary with a count of 1
            // WordCount Add(word, 1) This will add the key and value to the WordCount Dictionary
    }

    // Create a new method called WordsWithCountGreaterThan with a return type of a Dictionary!  
    public Dictionary<string, int> WordsWithCountGreaterThan(int count)
    {
        // TODO. Create a new dictionary to hold the NEW values after determining if a word count is 
        // greater than a specified number.  
        Dictionary<string, int> HigherWordCount = new Dictionary<string, int>();

        // For each Key Value Pair of type string and int named word in WordCount
            // If word.value is greater than count (Remember count was passed into the method above)
                // Add the word key and the word value into the new Dictionary created above        
        //return the new dictionary, i.e. HigherWordCount
    }
}

If you still have issues please let me know.

Thanks!!!

It looks like you asked this same question already.

But here's the hints I gave there about what your WordsWithCountGreaterThan method should have:

  • it should create a new Dictionary variable
  • it should have a loop to iterate the Wordcount
  • it should compare the count of each word to the passed-in argument
  • it should add both the word and the count to the new dictionary when the criterion is met
  • it should return the newly-created dictionary
