The individual calls to IEqualityComparer.Equals end and the IStructuralEquatable.Equals method returns a value either when a method call returns false or after all array elements or tuple components have been compared.
Bu tür bir muhaliflaştırma, makale mebdelıklarının sıralamasının önemli başüstüneğu durumlarda, strüktürel benzerliklerin yahut değişiklıkların belirlenmesine yardımcı olur.
This is really amazing code and works great for .NET Standard libraries. If you are in a .NET Core 2.1 application there is an even cooler way of doing this:
IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and not just compare references or individual values.
Although I think the gains from not boxing will be less than the cost for having CanEqual. In that case you should seal your types and you no longer need CanEqual. Sealing also özgü some performance benefits.

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

If you read this entire post and are thinking wow that is a lot of code and steps to remember then do hamiş fear because Dustin told me and showed me that Visual Studio will generate all of this for you!!!!! Check this out:
Net on a certain platform, I'm compelled to issue the standard warning hamiş to rely on the values of hashcodes or how they are computed, since it is not guaranteed to be the same across updates or platforms.
Tamam, makalede nekais kabil. Bunu tenkit olarak ikrar ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini de bilmiyor, performans ve başka konular karşı da rastgele bir düşün barındırmıtefsir. Siz biliyorsanız lütfen aydınlatır mkaloriız?

However, this is not so great if you are using the struct in a dictionary bey my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
