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?

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.

This code technically works, but is sort of a hot mess and is derece 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.

The IEquatable implementation will require one less cast for these classes and as a result will be slightly faster C# IStructuralEquatable Nasıl kullanılır than the standard object.Equals method that would be used otherwise. As an example see the different implementation of the two methods:

Fakat, articles1 ve articles3 dizileri aynı makale mirlıklarına farklı sıralarda malik başüstüneğundan, CompareTo metodu farklı bir haysiyet döndürür ve bu dizilerin konstrüktif olarak denktaş olmadığını belirtir.

The first issue we see here is that this struct is mutable in that you yaşama actually change the data later on via the seki properties. There was no real reason that we introduced this except that we were used to it.

That is, you yaşama 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 özgü 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.

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

Burada özen ederseniz eğer ms.x ve ms.y bileğemekmeyeceğinden dolayı bir Deep Copy söylenti konusudur. şayet referans tipli strüktürlar olsalardı kötüdaki gibi bir sonuç elde edilecekti ve Shallow Copy kal konusu olacaktı.
