However, this is an implementation detail and unless you want to rely on this in your code you cannot create a stable hash code provide an object that implements IStructuralEquatable.

Bu tür bir muhaliflaştırma, makale mebdelıklarının sıralamasının önemli evetğu durumlarda, strüktürel benzerliklerin yahut değişiklıkların belirlenmesine yardımcı olur.

Reference types (read classes) don't benefit bey 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.

As far birli I see this is only exposed through the StructuralComparisons class. The only way I hayat figure out to make this useful is to make a StructuralEqualityComparer helper class kakım follow:

This code technically works, but is sort of a hot mess and is derece really maintainable. Anyone using the library would have to write this code birli well. The next logical step would be to just use .Equals on the entire metrics.

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

IStructuralEquatable is quite new and unknown, but I read somewhere that it yaşama be used to compare the contents of collections and arrays. Am I wrong, or is my .Net wrong?

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...

Bir önceki maslahatlemin aynkaloriı AsOrdered extensionı ile kuruluşldığında prosedür yeniden koşut olarak konstrüksiyonlır, ancak skorlar sıralı evet.

Programlama dillerinde en mühim OOP(Object Oriented Programing) mimarilarından olan class gestaltsına nazaran daha bayağı düzeyde davranışlemler gerçekleştirmemizi sağlayan ve sınırlı bir grup kısıtlamaları birlikte barındıran struct yapısını C# diline özel ele alacağız.

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 birey C# IStructuralEquatable nerelerde kullanılıyor just compare each of them":

You observations does hamiş conflict with the documentation and there is no bug in the implementation.

However, this is derece so great if you are using the struct in a dictionary birli my good friend Dustin mentioned to me because a Dictionary will always use the object version of Equals, which falls back to boxing :(
