Add a GetHashCode method to the VocabularyWord class that returns an appropriate hash code.

task 1 of 1

VocabularyWord.cs 
using System;
namespace Treehouse.CodeChallenges
{
    public class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }

        public override string ToString()
        {
            return Word;
        }

        public override bool Equals(object obj)
        {
            if(!(obj is VocabularyWord))
            {
                return false;
            }

            var that = obj as VocabularyWord;


             }public override int GetHashCode() {

                 return this.Word.GetHashCode();
        }
}

I sent this in the editor and it worked for me; I just removed your 'this' from your hash code method: 

using System;
namespace Treehouse.CodeChallenges
{
    public class VocabularyWord
    {
        public string Word { get; private set; }

        public VocabularyWord(string word)
        {
            Word = word;
        }

        public override string ToString()
        {
            return Word;
        }

        public override bool Equals(object obj)
        {
            if(!(obj is VocabularyWord))
            {
                return false;
            }

            var that = obj as VocabularyWord;

            return this.Word.Equals(that.Word);
        }

        public override int GetHashCode() {

            return Word.GetHashCode();
        }
    }
}
