The "No" in part 2 of the answer is actually incorrect. Note: Tried editing the answer, but apparently some think that the highest rated answer being incorrect is derece reason enough to approve a correction edit.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Bey the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
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.
The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.
If those objects do not 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.
In my implementation I delegated the task of calculating C# IStructuralEquatable Kullanımı hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural hash code

Bir önceki işlemlemin aynkaloriı AsOrdered extensionı ile örgüldığında muamelat tekrar paralel olarak gestaltlır, ancak hatimelar sıralı olabilir.
Programlama dillerinde en mühim OOP(Object Oriented Programing) gestaltlarından olan class strüktürsına bakılırsa daha süssüz düzeyde çalışmalemler gerçekleştirmemizi sağlayıcı ve sınırlı bir öğür engellemelerı beraberinde çitndıran struct yapısını C# diline özel ele alacağız.
The contract of Equals differs from that of IStructuralEquatable, in that it indicates whether 2 objects are logically equal.
You observations does not conflict with the documentation and there is no bug in the implementation.
Burada uyanıklık ederseniz eğer ms.x ve ms.y değkârmeyeceğinden dolayı bir Deep Copy kelam konusudur. Eğer referans tipli bünyelar olsalardı süflidaki üzere bir sonuç elde edilecekti ve Shallow Copy hanek konusu olacaktı.
