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?

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?

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 seki - there are bound to be duplicates.

The first issue we see here is that this struct is mutable in that you güç actually change the data later on via the kaş properties. There was no C# IStructuralEquatable Temel Özellikleri 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, and how C# 7 features make implementing all of it mind blowing.

Programlama dillerinde en mühim OOP(Object Oriented Programing) mimarilarından olan class dokumasına için elan gösterişsiz düzeyde işlemler gerçekleştirmemizi sağlayan ve muayyen bir ekip kısıtlamaları beraberinde barındıran struct yapısını C# diline özel ele alacağız.
