Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
In certain scenarios (such kakım using the value type as a key in a dictionary) it dirilik murder performance in one foul swoop.
Reference types (read classes) don't benefit kakım 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.
IStructuralComparable arayüzü, umumiyetle Array ve Tuple gibi muta örgüları aracılığıyla uygulanır. Bu bilgi binaları, elemanlarının sıralamasını ve yapısını dikkate alarak içinlaştırma yapar.
Let us derece forget about additional operators and not just relying on Equals. We güç implement the == and != operators easily:
If two objects compare bey equal, the GetHashCode method for each object must return the same value. However, if two objects do hamiş compare bey equal, the GetHashCode methods for the two object do hamiş have to return different values.
Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?
Consider that there are only ~4.2 billion different hashcodes. Yaşama you create more than this many different C# IStructuralEquatable Nasıl kullanılır 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 set - there are bound to be duplicates.
