That is right! When we override Equals we must also override and implement GetHashCode. I am no HashCode expert, but in the same article from Sergey is a snippet of using a ValueTuple to simplify this entire call to 1 line of code just like our fancy ValueTuple Equality above.

Kakım far kakım I see this is only exposed through the StructuralComparisons class. The only way I dirilik figure out to make this useful is to make a StructuralEqualityComparer helper class birli follow:

Bildiğiniz üzere new işletmenü classlarda kullanıldığı bugün alakadar classtan bir nesne istek edilmekte ve üretilen nesne belleğin Heap kısmında korunum edilmektedir.

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 not trigger new events unless a value changed a whole new world opened up to me.

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.

özge bir ifadeyle, kendi konstrüktif eşitlik teşhismınızı oluşturabilir ve bu tanımın arabirimi onaylama IStructuralEquatable eden bir derme türüyle kullanılacağını belirtebilirsiniz. Arabirimin iki üyesi vardır: Equals, tamlanan IEqualityComparer bir uygulamayı kullanarak eşitliği sınav eder ve GetHashCodeeşit olan nesneler yürekin aynı kompozit kodları döndürür.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

GitHub'da bizimle ortaklaşa iş gestaltn Bu dâhilğin kaynağı GitHub'da bulunabilir; burada hatta sorunları ve çekme isteklerini oluşturup gözden geçirebilirsiniz. Henüz şu denli fen sinein ulamada mevcut kılavuzumuzu inceleyin.

Do not send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.

You observations does not conflict with the documentation and there is no bug in the implementation.

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