I don't understand what has to be build?
using System;
namespace Treehouse.CodeChallenges
{
class VocabularyWord
{
public string Word { get; private set; }
public VocabularyWord(string word)
{
Word = word;
}
public string VocabularyWordToString(string word)
{
Word = word.ToString();
return Word;
}
}
}

namespace Treehouse.CodeChallenges
{
class VocabularyWord
{
public string Word { get; private set; }
public VocabularyWord(string word)
{
Word = word;
}
public string ToString()
{
return Word;
}
}
}
So you can do
VocabularyWord word = new VocabularyWord("House");
string vocab = word.ToString() //Will return "House" so vocab = "House"
The ToString() method is usually overidden in your classes since it is defined in the Object class.
So a correct way to define a ToString() method would be
public override string ToString()
{
return Word;
}

I don't really get this.. It already returns a string type value. Why do we need to override it??
The syntax on the MSDN page is:
public virtual string ToString()

9,864 PointsOke i understand the function of override, but why override string?
I mean the function of this to string method.
