In this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

This is really amazing code and works great for .Safi Standard libraries. If you are in a .Safi Core 2.1 application there is an even cooler way of doing this:

Does anyone know what happens if you do derece implement iequtalable when using generic collections? 2

Although I think the gains from derece boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also has some performance benefits.

That is, you kişi create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface katışıksız two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

You observations does derece conflict with the documentation and there is no bug in the implementation.
