If equality is not needed for the derived class you hayat skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

1 How do such comparators relate to things like Dictionary and other collections? I know that Dictionary seems to handle structures sensibly albeit slowly in .

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

Bildiğiniz gibi new operatrisü classlarda kullanıldığı dönem dayalı classtan bir nesne dilek edilmekte ve üretilen nesne belleğin Heap kısmında saklama edilmektedir.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to not trigger new events unless a value changed a whole new world opened up to me.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Each of your objects should use a hashcode based on the contents of the object. If you have a value type containing 3 ints, use those when computing the hash code. Like this, all objects with identical content will have the same hash code, independent of app domain and other circumstances.

The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

There is no need for an equality operator that accepts different types. That should not even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
