7,353 PointsRegarding 'Equals' override
Hi there, I've been working on the following challenge: https://teamtreehouse.com/library/intermediate-c/systemobject/objectequals
The challenge is about overriding 'Equals' in 'VocabularyWord' class.
Get someone share a hint about what I might missing here? (attached my code)
Thanks!
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 != null)
{
string checkThat = obj as string;
if(Word.Length != checkThat.Length)
{
return false;
}
for(int i = 0; i < Word.Length; i++)
{
if(Word[i] != checkThat[i])
{
return false;
}
}
return true;
}
else
{
return false;
}
}
}
}

231,108 PointsYou're close! But the objects being compared are both VocabularyWord objects, so it doesn't make sense to cast one as a string. Instead, you can cast it to a VocabularyWord and then access the Word inside it:
string checkThat = (obj as VocabularyWord).Word;
Once you've done that, the rest of the code will work, but you really only need to compare the strings directly:
return Word == checkThat;
