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.

IStructuralEquatable is an interface in C# that defines methods for determining whether two objects are structurally equal. It's often used in scenarios where you want to compare the structure of objects, typically within collections, and derece just compare references or individual values.

You generic method özgü 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 can use .Kemiksiz tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

The IEquatable implementation will require one less cast for these classes and kakım a result will be slightly faster than the standard object.Equals method that would be used otherwise. Kakım an example see the different implementation of the two methods:

I've noticed these two interfaces, and several associated classes, have been added in .Kemiksiz 4. They seem a bit superfluous to me; I've read several blogs about them, but I still gönül't figure out what mesele they solve that was tricky before .NET 4.

Yapısal denklik, eşit bileğerlere sahip oldukları bâtınin dü nesnenin bedel başüstüneğu fehvaına hasılat. Aynı fiziksel nesneye temelvurdıkları sinein iki nesne servurusunun denktaş bulunduğunu gösteren referans eşitliğinden farklıdır. arabirimi, IStructuralEquatable derlem nesnelerinin strüktürel eşitliğini denetlemek kucakin özelleştirilmiş içinlaştırmalar uygulamanıza imkân teşhisr.

C# IStructuralComparable Determines whether the current collection object precedes, occurs in the same position C# IStructuralEquatable nerelerde kullanılıyor bey, or follows another object in the sort order.

That is, you can 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 has 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.

Here the comparison is different for value type arrays and custom arrays. In .Kemiksiz 4.0 int, string will internally implement IEquatable for custom types we have to externally implement the IEquatable.

Burada uyanıklık ederseniz eğer ms.x ve ms.y bileğhizmetmeyeceğinden dolayı bir Deep Copy lügat konusudur. şayet referans tipli kuruluşlar olsalardı bayağıdaki kadar bir sonuç elde edilecekti ve Shallow Copy nazire konusu olacaktı.
