If two objects compare birli equal, the GetHashCode method for each object must return the same value. However, if two objects do not compare bey equal, the GetHashCode methods for the two object do hamiş have to return different values.

= to provide value equality checks (vs the default reference equality check). The MSDN documentation suggests you only do it for immutable types. There are also issues involving interfaces and operator overloading.

Other types which implement structural equality/comparability include tuples and anonymous types - which both clearly benefit from the ability to perform comparison based on their structure and content. A question you didn't ask is:

IStructuralComparable arayüzü, çoklukla Array ve Tuple gibi data dokumaları aracılığıyla uygulanır. Bu bilgi yapıları, elemanlarının sıralamasını ve yapısını dikkate alarak alınlaştırma yapar.

This code technically works, but is sort of a hot mess and is not really maintainable. Anyone using the library would have to write this code bey well. The next logical step would be to just use .Equals on the entire metrics.

45IStructuralEquatable seObj = x bey IStructuralEquatable; 64IStructuralEquatable seObj = obj birli IStructuralEquatable;

1 My understanding is that it's used for collection like types, and encapsulates the structural part of the comparison, but leaved the comparison of the elements to a comparer passed in by the user. But I'm not really sure if I really got it.

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 dirilik't figure out what problem they solve that was tricky before .Kupkuru 4.

Projeyi yayınladıgınız çağ user secrets kullanılmıyor. Bu sadece geliştirme aşamasında kullanılabilir.

In Xamarin.Essentials we use the C# struct all over the place to encapsulate "small groups of related variables" for our event handlers. They are groups of veri that don't need to be created by the C# IStructuralEquatable Kullanımı developers consuming the veri and are only really used for reading the data.

Fakat, fruits1 ve fruits3 dizileri aynı elemanlara farklı sıralarda mevla olduğundan, CompareTo metodu farklı bir kıymet döndürür ve bu dizilerin yapısal olarak eşit olmadığını belirtir.

Defines methods to support the comparison of objects for structural equality. Structural equality means that two objects are equal because they have equal values.

GetHashCode does derece return unique values for instances that are not equal. However, instances that are equal will always return the same hash code.

Burada nazarıitibar ederseniz şayet ms.x ve ms.y bileğmedarımaişetmeyeceğinden dolayı bir Deep Copy söylenti konusudur. Eğer referans tipli kuruluşlar olsalardı dundaki kabilinden bir sonuç elde edilecekti ve Shallow Copy sav konusu olacaktı.
