Reference types (read classes) don't benefit birli much. The IEquatable implementation does let you avoid a cast from System.Object but that's a very trivial gain. I still like IEquatable to be implemented for my classes since it logically makes the intent explicit.

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

Değişik bir ifadeyle, kendi yapısal eşitlik tanımınızı oluşturabilir ve bu teşhismın arabirimi ikrar IStructuralEquatable eden bir koleksiyon türüyle kullanılacağını belirtebilirsiniz.

Kupkuru on a certain ortam, I'm compelled to issue the standard warning hamiş 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.

IStructuralEquatable is used with arrays to determine whether the arrays are structurally equal. The StructuralEqualityComparer.Equals method is used for this purpose.

Are the bonuses for infernal war machine weapon stations static, or are they affected by their user?

Specifically, I do not know the exact type of the object. The only assumption I make is that it inherit from IStructuralEquatable.
