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).

Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

IStructuralComparable arayüzü, çoklukla Array ve Tuple kabil data mimariları aracılığıyla uygulanır. Bu data konstrüksiyonları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak alınlaştırma yapar.

I'm amazed that the most important reason is hamiş mentioned here. IEquatable was introduced mainly for structs for two reasons:

Your concern is that Object.GetHashCode() does derece provide values that are stable and the concern is very valid birli birey be seen in the first box headed by Caution in the documentation:

So, I am apparently wrong bey unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed seki of values a requirement?

I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still gönül't figure out what problem they solve that was tricky before .Safi 4.

The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

This member is an explicit interface member implementation. It can be used C# IStructuralEquatable Temel Özellikleri only when the Array instance is cast to an IStructuralEquatable interface.

Tamam, makalede eksiklikler olur. Bunu eleştiri olarak akseptans ediyorum. Işlevsel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve başka mevzular karşı da herhangi bir düşünüm barındırmıyorum. Siz biliyorsanız lütfen aydınlatır mısınız?

GetHashCode does derece return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
