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 not reason enough to approve a correction edit.

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.

Ee kavlükarar gelimi struct örgüsında da new operatrisünü kullanırsak şayet evet alakalı kuruluşdan bir nesne üretilecektir lakin struct bir fehamet tipli mütehavvil mimarisında başüstüneğundan dolayı o nesne belleğin Stack kısmında koruma edilecektir.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

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

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

Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may hamiş give you the correct results in this super simple example:

When working with collections or structures where the order of elements matters, and you want to compare their structures, IStructuralEquatable dirilik be useful.

Now that our struct is immutable the actual issue comes up when you need to compare these values. When I started to write the code to fix the bug I just decided that "hey I have the old values, I güç just compare each of them":
