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

They both do the same unless they are specifically overloaded within the object to do something else.

A quote from the Jon Skeet Article mentioned elsewhere.

The Equals method is just a virtual one defined in System.Object, and overridden by whichever classes choose to do so. The == operator is an operator which can be overloaded by classes, but which usually has identity behaviour.

The keyword here is USUALLY. They can be written to do whatever the underlying class wishes and in no way do they have to do the same.
