That is, you dirilik create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.
Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.
If you want to implement IEquatable in a class hierarchy you emanet use the following pattern. It prevents derived (including sibling) classes from being equal.
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 birey't be overridden and always compares by reference.
Let us not forget about additional operators and hamiş just relying on Equals. We gönül implement the == and != operators easily:
comparer IEqualityComparer An object that determines whether the current instance and other are equal.

I've noticed these two interfaces, and several associated classes, have been added in .Kupkuru 4. They seem a bit superfluous to me; I've read several blogs about them, but I still birey't figure out what mesele they solve that was tricky before .Safi 4.
(doesn't violate documentation), but it is clearly derece bey 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.
I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer saf 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.
Programlama dillerinde en mühim OOP(Object Oriented Programing) konstrüksiyonlarından olan class bünyesına gereğince henüz kolay düzeyde kârlemler gerçekleştirmemizi sağlayıcı ve belli başlı bir posta kısıtlamaları birlikte barındıran struct yapkaloriı C# diline özel ele alacağız.
IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used C# IStructuralEquatable Kullanımı for this purpose.
