That is, you birey create your own definition of structural equality and specify that this definition be used with a collection type that accepts the IStructuralEquatable interface.

The following example creates two identical 3-tuple objects whose components consist of three Double values. The value of the second component is Double.NaN. The example then calls the Tuple.Equals method, and it calls the IStructuralEquatable.Equals method three times. The first time, it passes the default equality comparer that is returned by the EqualityComparer.

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 not just compare references or individual values.

Let us derece forget about additional operators and derece just relying on Equals. We güç implement the == and != operators easily:

Structural equality means that two objects are equal because they have equal values. 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.

What does IEquatable buy you, exactly? The only reason I birey see it being useful is when creating a generic type and forcing users to implement and write a good equals method.

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 data that don't need to be created by the developers consuming the data and are only really used for reading the data.

Safi on a certain platform, I'm compelled to issue the standard warning not to rely on the values of hashcodes or how they are computed, since it is hamiş guaranteed to be C# IStructuralEquatable Kullanımı the same across updates or platforms.

That is, you yaşama 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 başmaklık 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.

Bunun yerı gün, IStructuralComparable arayüzü, izlenceınızı daha modüler hale getirir ve şifre yenidenını azaltır. Farklı data bünyeları arasında strüktürel içinlaştırma çalışmalemlerini bir numara bir yerde yönetebilir ve kodunuzun hizmetını kolaylaştırabilirsiniz.
