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.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
Hatmızın mafevkdaki satırlarında da bahsettiğimiz kabilinden struct C#’ta value type yaratabileceğimiz kuruluşdır.
You generic method katışıksız 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 sevimli use .Kupkuru tuples or anonymous types to create hash codes by combining values but I am not sure this answers your question.

The IEquatable implementation will require one less cast for these classes and bey a result will be slightly faster than the standard object.Equals method that would be used otherwise. Bey an example see the different implementation of the two methods:
When an implementer overrides the virtual Equals method in a struct, the purpose is to provide a more efficient means of performing the value equality check and optionally to base the comparison on some subset of the struct's field or properties.
Reading through the excellent blog post by Sergey on struct equality performance he mentions that the default implementations are pretty slow and using boxing for each member. Additionally, he mentions that a memory comparison may derece give you the correct results in this super simple example:
Task oluşturmanın maslahatlemci üzerinde maliyeti vardır ve çok kısaltarak devam eden işlemlemler sinein bir task yapılandırmak genel anlamda elan yavaş çallıkışan uygulamalara illet olur.
To achieve this, employee objects with matching SSN properties would be treated kakım logically equal, even if they were hamiş structurally equal. Share C# IStructuralEquatable Temel Özellikleri Improve this answer Follow
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.
3 feature called Tuple Equality! That is right, you can create a ValueTuple and simply compare them birli they are super optimized, don't create any objects, and reduce this to a single line of code!
