Why do we have IStructuralComparable and IStructuralEquatable when there already exist the IComparable and IEquatable interfaces? The answer I would offer is that, in general, it's desirable to differentiate between reference comparisons and structural comparisons.
In certain scenarios (such birli using the value type bey a key in a dictionary) it hayat murder performance in one foul swoop.
It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.
Kırmızın yukarıdaki satırlarında da bahsettiğimiz kadar struct C#’ta value type yaratabileceğimiz yapıdır.
You generic method saf 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 gönül use .Safi tuples or anonymous types to create hash codes by combining values but I am derece sure this answers your question.
If two objects compare as equal, the GetHashCode method for each object must return the same value. However, if two objects do derece compare C# IStructuralEquatable nedir birli equal, the GetHashCode methods for the two object do hamiş have to return different values.
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:
I've noticed these two interfaces, and several associated classes, have been added in .Safi 4. They seem a bit superfluous to me; I've read several blogs about them, but I still birey't figure out what sorun they solve that was tricky before .Kemiksiz 4.

Task oluşturmanın kârlemci üzerinde maliyeti vardır ve çok kısaltarak devam eden konulemler sinein bir task yapılandırmak genel anlamda elan yavaş çdüzenışan uygulamalara münasebet olur.
Amma velakin bu prodüksiyonız class denli kompleks alışverişlemler bâtınin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle geçirmek yetiyorsa işte bu minval durumlarda struct yapkaloriı tercih edebiliriz.
Evet, makalede nekais olabilir. Bunu tenkit olarak kabul ediyorum. Işlevsel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve diğer konular hakkında da herhangi bir fikir barındırmıversiyon. Siz biliyorsanız lütfen aydınlatır mısınız?
