When can a == b be false and a.Equals(b) true?

Question

I ran into this situation today. I have an object which I\'m testing for equality; the Create() method returns a subclass implementation of MyObject.

MyObject         


        

Answer 1

I believe that a == b will check if the referenced object is the same.

Usually to see if the value is the same a.Equals(b) is used (this often needs to be overridden in order to work).
