Kırmızın mafevkdaki satırlarında da bahsettiğimiz kabilinden struct C#’ta value type yaratabileceğimiz kuruluşdır.
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 katışıksız some performance benefits.
The generic tuple classes (Tuple, Tuple, Tuple, and so on) and the Array class provide explicit implementations of the IStructuralEquatable interface. By casting (in C#) or converting (in Visual Basic) the current instance of an array or tuple to an IStructuralEquatable interface value and providing your IEqualityComparer implementation kakım an argument to the Equals method, you gönül define a custom equality comparison for the array or collection.
1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm derece really sure if I really got it.
