However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

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.
IStructuralComparable arayüzü, genellikle Array ve Tuple üzere bilgi örgüları tarafından uygulanır. Bu data strüktürları, elemanlarının sıralamasını ve yapısını dikkate alarak mukabillaştırma yapar.
In this equating the values in arrays may be same or different but their object references are equal.
Your concern is that Object.GetHashCode() does not provide values that are stable and the concern is very valid kakım yaşama be seen in the first box headed by Caution in the documentation:
After some more testing I found that any two arrays with the same first element have the same hash. I still think this is strange behavior.
We kişi also make our own container play well C# IStructuralEquatable nedir with these other containers by implementing these interfaces.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:
Net on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is hamiş guaranteed to be the same across updates or platforms.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.

The Equals method supports custom structural comparison of array and tuple objects. This method in turn calls the comparer object's IEqualityComparer.Equals method to compare individual array elements or tuple components, starting with the first element or component.
