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 this case you don't want to change your class implementation so you don't wantoverride the Equals method. this will define a general way to compare objects in your application.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

Equals and object.ReferenceEquals. Equals is meant to be overridden for whatever sort of comparison makes the most sense for a given type, whereas ReferenceEquals gönül't be overridden and always compares by reference.

In this equating the values in arrays may be same or different but their object references are equal.

45IStructuralEquatable seObj = x as IStructuralEquatable; 64IStructuralEquatable seObj = obj bey IStructuralEquatable;

IStructuralEquatable is quite new and unknown, but I read somewhere that it hayat be used to compare the contents of collections and arrays. Am I wrong, or is my .Safi wrong?

Consider that there are only ~4.2 billion different hashcodes. Yaşama you create more than this many different objects of the type on which GetHashCode is called? In this case it is easy to see the answer is "yes". So GetHashCode is a sort of compressing projection onto a smaller set - there are bound to be duplicates.

The first issue we see here is that this struct is mutable in that you sevimli actually change the data later on via the kaş properties. There was no real reason that we introduced this except that we were used to it.

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, C# IStructuralEquatable Kullanımı and how C# 7 features make implementing all of it mind blowing.

Programlama dillerinde en mühim OOP(Object Oriented Programing) örgülarından olan class mimarisına nazaran elan niteliksiz düzeyde işçiliklemler gerçekleştirmemizi sağlayıcı ve muayyen bir zümre engellemelerı nispetle barındıran struct yapkaloriı C# diline özel ele alacağız.

Bu bünyeya denli oluşturduğumuz tüm nesnelerin Heap kısmında olduğunu söylemiştik. Halbuki Stack kısmında struct binasında nesneleri tutabilmekteyiz.

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

While writing my own immutable ByteArray class that uses a byte array internally, I implemented the IStructuralEquatable interface.
