So, I am apparently wrong as unequal objects may have equal hash codes. C# IStructuralEquatable Nasıl kullanılır But isn't GetHashCode returning a somewhat randomly distributed grup of values a requirement?

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

(doesn't violate documentation), but it is clearly not as good bey it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.
