Problem

I don't know what is with my code here ??

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(VocabularyWord that)
        {
            if(that.Word == this.Word)
            {
                return true;
            }
            else
            {
                return false;
            }
        }
    }
}

Here's a few hints:

  • an override must have the same signature as the virtual method
  • the signature of the base "Equals" includes an argument of type object
  • the internal logic should include a test of the object's type

You might want to review the example implementation of the override shown in the video.
