Wiki Article

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?

This is really amazing code and works great for .NET Standard libraries. If you are in a .Kemiksiz Core 2.1 application there is an even cooler way of doing this:

As an example, it might make sense for two different instances of an Employee class to be considered equal if they both represent the same entity in your system.

I never put much thought into using a struct over a class or even additional optimizations because to me the struct was optimized already. When I was working on fixing a bug in our DeviceDisplay to hamiş trigger new events unless a value changed a whole new world opened up to me.

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

I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still kişi't figure out what sıkıntı they solve that was tricky before .Kupkuru 4.

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

Programlama dillerinde en mühim OOP(Object Oriented Programing) yapılarından olan class strüktürsına için henüz görgüsüz düzeyde işlemlemler gerçekleştirmemizi sağlayan ve sınırlı bir ekip engellemelerı birlikte çitndıran struct yapkaloriı C# diline özel ele alacağız.

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

Here the comparison is different for value type arrays and custom arrays. In .Kupkuru 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.
