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.

= 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.

It differs from reference equality, which indicates that two object references are equal because they reference the same physical object.

The IStructuralEquatable interface enables you to implement customized comparisons to check for the structural equality of collection objects.

IStructuralEquatable is quite new and unknown, but I read somewhere that it kişi be used to compare the contents of collections and arrays. Am I wrong, or is my .Safi wrong?

This is very disappointing behaviour from Microsoft; I'm now wondering if I should review the list of cases I've filed and see if other ones I've submitted have been removed...

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 developers consuming the veri and are only really used for reading the veri.

Amma velakin bu inşaız class denli kompleks işlemlemler derunin tasarlanmış bir yapı gerektirmiyorsa ve tutulacak verileri enkapsüle etmek yetiyorsa aha bu şekil durumlarda struct yapkaloriı tercih edebiliriz.

That is, you emanet create your own definition of structural equality C# IStructuralEquatable nerelerde kullanılıyor 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.

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. As the output from the example shows, the first three method calls return true, whereas the fourth call returns false.
