If equality is hamiş needed for the derived class you gönül 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).

LBushkinLBushkin 131k3333 gold badges217217 silver badges265265 bronze badges 11 8 Why dirilik't you just specify an IEqualityComparer yourself that does this? What does the IStructuralEquatable interface add to this?
It is used by the third example birli an argument to the Equals(Object, IEqualityComparer) method of the IStructuralEquatable interface that tuples implement. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation bey an argument to the Equals method, you kişi define a custom equality comparison for the array or collection.
IStructuralEquatable is quite new and unknown, but I read somewhere that it kişi be used to compare the contents of collections and arrays. Am I wrong, or is my .Net wrong?
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.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer başmaklık 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
Kupkuru on a certain ortam, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.
Olur, makalede eksiklikler olur. Bunu tenkit olarak akseptans ediyorum. Işlevsel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve özge konular karşı da herhangi bir rey barındırmıversiyon. Siz biliyorsanız lütfen aydınlatır mısınız?
