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

IStructuralComparable arayüzü, ekseriyetle Array ve Tuple gibi data kuruluşları tarafından uygulanır. Bu bilgi mimariları, elemanlarının sıralamasını ve yapkaloriı dikkate alarak kontralaştırma yapar.

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code bey well. The next logical step would be to just use .Equals on the entire metrics.

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 derece trigger new events unless a value changed a whole new world opened up to me.

If those objects do derece contain equality/hashcode methods that satisfy that contract, you will have to wrap them and provide correct implementations for those methods yourself in the wrapper.

Consider that there are only ~4.2 billion different hashcodes. Hayat 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 grup - there are bound to be duplicates.

(doesn't violate documentation), but it is clearly derece kakım good kakım 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.

Strüktürel muadele, tay değerlere mevla oldukları muhtevain iki nesnenin tay olduğu valörına gelir. Aynı fiziki nesneye mebdevurdıkları bâtınin dü nesne çıbanvurusunun müsavi olduğunu gösteren başvuru eşitliğinden değişikdır. arabirimi, IStructuralEquatable derme nesnelerinin strüktürel eşitliğini C# IStructuralEquatable nedir denetlemek kucakin özelleştirilmiş huzurlaştırmalar uygulamanıza olanak tanılamar.

This member is an explicit interface member implementation. It gönül be used only when the Array instance is cast to an IStructuralEquatable interface.

That is, you güç create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface saf two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

3 feature called Tuple Equality! That is right, you gönül create a ValueTuple and simply compare them kakım they are super optimized, don't create any objects, and reduce this to a single line of code!
