C# IStructuralEquatable nerelerde kullanılıyor Için Adım Haritaya göre Yeni Adım

If equality is hamiş needed for the derived class you hayat skip IEquatable but you need to override the CanEqual to prevent it being equal with base classes (unless of course they should be considered equal).

In certain scenarios (such as using the value type kakım a key in a dictionary) it hayat murder performance in one foul swoop.

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.

I'm amazed that the most important reason is derece mentioned here. IEquatable was introduced mainly for structs for two reasons:

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

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 C# IStructuralEquatable nedir hamiş really sure if I really got it.

This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

(doesn't violate documentation), but it is clearly hamiş as good birli 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.

I had the same question. When I ran LBushkin's example I was surprised to see that I got a different answer! Even though that answer başmaklık 8 upvotes, it is wrong. After a lot of 'reflector'ing, here is my take on things.

Programlama dillerinde en mühim OOP(Object Oriented Programing) konstrüksiyonlarından olan class kuruluşsına için henüz cılız düzeyde işçiliklemler gerçekleştirmemizi sağlayan ve makul bir ekipman kısıtlamaları nezdinde çitndıran struct yapısını C# diline özel ele alacağız.

Do derece send hash codes across application domains or processes. In some cases, hash codes may be computed on a per-process or per-application domain basis.
