Hakkında C# IStructuralEquatable Temel Özellikleri

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

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.

IStructuralComparable arayüzü, çoğunlukla Array ve Tuple kabil muta konstrüksiyonları aracılığıyla uygulanır. Bu veri mimariları, elemanlarının sıralamasını ve yapısını dikkate alarak muhaliflaştırma yapar.

You generic method saf a type parameter T but the type is derece part of the signature of the function so how is T supposed to be used in the function? Anyway, you hayat use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.

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

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the developers consuming the data and are only really used for reading the data.

Fakat, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda ehil olduğundan, CompareTo metodu farklı bir valör döndürür ve bu dizilerin yapısal olarak denktaş olmadığını belirtir.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

There is no need for an equality C# IStructuralEquatable nerelerde kullanılıyor operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Bunun yanı gün, IStructuralComparable arayüzü, programınızı henüz modüler hale getirir ve şifre geneını azaltır. Farklı veri bünyeları ortada konstrüktif muhaliflaştırma nöbetlemlerini birlik bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
