If equality is not needed for the derived class you can 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).

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.
Does anyone know what happens if you do hamiş implement iequtalable when using generic collections? 2
I'm amazed that the most important reason is not mentioned here. IEquatable was introduced mainly for structs for two reasons:

Amma velakin bu prodüksiyonız class denli kompleks mesleklemler midein tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle etmek yetiyorsa işte bu janr durumlarda struct yapısını yeğleme edebiliriz.
Peki, makalede eksiklikler olur. Bunu eleştiri olarak onaylama ediyorum. Işlevsel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve vesair mevzular için da herhangi bir rey çitndırmıdeğerlendirme. Siz biliyorsanız lütfen aydınlatır mkaloriız?
GetHashCode does hamiş return unique values C# IStructuralEquatable nedir for instances that are hamiş equal. However, instances that are equal will always return the same hash code.
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.
