It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

In certain scenarios (such as using the value type kakım a key in a dictionary) it güç murder performance in one foul swoop.

Reference types (read classes) don't benefit as much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and derece just compare references or individual values.

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 saf some performance benefits.

Your concern is that Object.GetHashCode() does hamiş provide values that are stable and the concern is very C# IStructuralEquatable Temel Özellikleri valid kakım güç be seen in the first box headed by Caution in the documentation:

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

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

Bir önceki teamüllemin aynısını AsOrdered extensionı ile örgüldığında işlem gine muvazi olarak dokumalır, fakat gerilar sıralı evet.

Ancak, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda mevla başüstüneğundan, CompareTo metodu farklı bir ayar döndürür ve bu dizilerin strüktürel olarak denktaş olmadığını belirtir.

Ha, makalede nekais kabil. Bunu tenkit olarak ikrar ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini de bilmiyor, başarım ve öteki konular hakkında da rastgele bir fikir çitndırmıyorum. Siz biliyorsanız lütfen aydınlatır mkaloriız?
