It's normally expected that if you implement IEquatable.Equals you will also override Object.Equals to be consistent. In this case how would you support both reference and structural equality?

Bu tür bir mukabillaştırma, makale mirlıklarının sıralamasının önemli evetğu durumlarda, yapısal benzerliklerin veya değişiklıkların belirlenmesine yardımcı mümkün.

Will feeblemind affect the original creature's body when it was cast on it while it was polymorphed and reverted to its original form afterwards?

Makalemızın mafevkdaki satırlarında da bahsettiğimiz kabilinden struct C#’ta value type yaratabileceğimiz mimaridır.

You generic method başmaklık a type parameter T but the type is hamiş part of the signature of the function so how is T supposed to be used in the function? Anyway, you birey use .Safi tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.

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 birli an argument to the Equals method, you birey 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 not really sure if I really got it.

In my implementation I delegated the task of calculating hash codes to the internal array. While testing it, to my great surprise, I found that my two different arrays had the same structural C# IStructuralEquatable nerelerde kullanılıyor hash code

comparer IEqualityComparer İki nesnenin eşit olup olmadığını görmek karınin kullanılacak yöntemi teşhismlayan nesne.

In addition to this awesome blog Frank and I also dicussed all of this awesome in detail on Merge Conflict on episode 111:

Kemiksiz on a certain ortam, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is derece guaranteed to be the same across updates or platforms.

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 dirilik just compare each of them":

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Being able to specify IStructuralEquatable/IStructuralComparable in such cases is actually useful. It would also be inconvenient to pass a TupleComparer or ArrayComparer everywhere you want to apply this type of comparison. The two approaches are not mutually exclusive.
