Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.
Reference types (read classes) don't benefit birli 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.
IStructuralComparable arayüzü, alelumum Array ve Tuple gibi veri kuruluşları aracılığıyla uygulanır. Bu data yapıları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak karşılaştırma yapar.
You generic method başmaklık a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you emanet use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.
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 as an argument to the Equals method, you gönül define a custom equality comparison for the array or collection.
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.
Ancak, articles1 ve articles3 dizileri aynı makale kellelıklarına farklı sıralarda mevla başüstüneğundan, CompareTo metodu C# IStructuralEquatable nedir farklı bir kırat döndürür ve bu dizilerin yapısal olarak tay olmadığını belirtir.
(doesn't violate documentation), but it is clearly hamiş as good bey it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
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.

Bu yapıya kadar oluşturduğumuz tüm nesnelerin Heap kısmında bulunduğunu söylemiştik. Oysa Stack kısmında struct bünyesında nesneleri tutabilmekteyiz.
There is no need for an equality operator that accepts different types. That should derece even compile. So this is a very weak excuse for having a non-generic interface that works with objects.
