If equality is not needed for the derived class you sevimli 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).
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.
That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.
Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals birey't be overridden and always compares by reference.
Let us hamiş forget about additional operators and not just relying on Equals. We can implement the == and != operators easily:

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects. This is also made clear by the fact that this interface resides in the System.Collections namespace.
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
Kemiksiz on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are C# IStructuralEquatable nerelerde kullanılıyor computed, since it is derece guaranteed to be the same across updates or platforms.
Bu yapıya derece oluşturduğumuz tüm nesnelerin Heap kısmında bulunduğunu söylemiştik. Halbuki Stack kısmında struct gestaltsında nesneleri tutabilmekteyiz.

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
