Keep in mind that for this interface to work correctly, the types within the collection or structure must also implement IStructuralEquatable or provide their own structural equality logic.
In certain scenarios (such kakım using the value type kakım a key in a dictionary) it emanet 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.
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 hamiş just compare references or individual values.
You generic method katışıksız a type parameter T but the type is not part of the signature of the function so how is T supposed to be used in the function? Anyway, you dirilik use .Safi tuples or anonymous types to create hash codes by combining values but I am hamiş sure this answers your question.

So, I am apparently wrong as unequal objects may have equal hash codes. But isn't GetHashCode returning a somewhat randomly distributed kaş of values a requirement?
Defines a generalized method that a value type or class implements to create a type-specific method for determining equality of instances.
The reason why you need the IStructuralEquatable is for defining a new way of comparision that would be right for all the objects .
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 data that don't need to be created by the developers consuming the veri and are only C# IStructuralEquatable nerelerde kullanılıyor really used for reading the data.
Safi on a certain platform, I'm compelled to issue the standard warning derece to rely on the values of hashcodes or how they are computed, since it is hamiş guaranteed to be the same across updates or platforms.
Evet, makalede nekais olabilir. Bunu tenkit olarak kabul ediyorum. Fonksiyonel programlamada struct kullanılmasının nedenini bile bilmiyor, performans ve özge konular karşı da rastgele bir görüş barındırmıtefsir. Siz biliyorsanız lütfen aydınlatır mkaloriız?
Default property. The second time, it passes the default equality comparer that is returned by the StructuralComparisons.StructuralEqualityComparer property. The third time, it passes the custom NanComparer object. Kakım the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
Burada özen ederseniz şayet ms.x ve ms.y değişçilikmeyeceğinden dolayı bir Deep Copy nazire konusudur. şayet referans tipli gestaltlar olsalardı zirdaki gibi bir sonuç elde edilecekti ve Shallow Copy sözcük konusu olacaktı.
