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.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

Bildiğiniz kadar new cerrahü classlarda kullanıldığı dönem dayalı classtan bir nesne dilek edilmekte ve üretilen nesne belleğin Heap kısmında saklama edilmektedir.

– Royi Namir Commented Mar 3, 2012 at 18:04 @RoyiNamir user844541's answer is correct, but maybe it is still hard for you to understand without a concrete example, if you are familiar with IEqualityComparer and how it is used by Linq's Distinct(), then after check the source code to see how it implement IStructuralEquatable on referencesource.microsoft.com/#mscorlib/system/collections/…, then you will see how it work.

1 My understanding is that it's used for collection like types, and encapsulates the C# IStructuralEquatable Nasıl kullanılır 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.

Ancak, articles1 ve articles3 dizileri aynı makale başlangıçlıklarına farklı sıralarda mevla evetğundan, CompareTo metodu farklı bir haysiyet döndürür ve bu dizilerin yapısal olarak yeksan olmadığını belirtir.

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

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

That is, you kişi create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface. The interface özgü two members: Equals, which tests for equality by using a specified IEqualityComparer implementation, and GetHashCode, which returns identical hash codes for objects that are equal.

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

Burada uyanıklık ederseniz eğer ms.x ve ms.y bileğemekmeyeceğinden dolayı bir Deep Copy laf konusudur. şayet referans tipli konstrüksiyonlar olsalardı aşağıdaki kabil bir sonuç elde edilecekti ve Shallow Copy kavil konusu olacaktı.
