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

Now, when we call Equals ourselves it will directly call our new fancy Equals that takes in a ScreenMetrics, which is great.

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.

Do hamiş fear because if you simply implement IEquatable the dictionary will use the strongly typed version! The nice thing is that we kind of actually already did this! So now we just have to do this:

Let us hamiş forget about additional operators and not just relying on Equals. We emanet implement the == and != operators easily:

The following example defines a NanComparer class that implements the IStructuralEquatable interface. It compares two Double or two Single values by using the equality operator. It passes values of any other type to the default equality comparer.

Is Légal’s reported “psychological trick” considered fair play or unacceptable conduct under FIDE rules?

Defines a C# IStructuralEquatable Nasıl kullanılır generalized method that a value type or class implements to create a type-specific method for determining equality of instances.

(doesn't violate documentation), but it is clearly not birli good kakım it would be if 0 were replaced with i. Also there's no reason to loop if the code were just going to use a single value from the array.

In all my years of development and blogging I never thought I would be writing about how amazing a C# struct is, how awesome IEquatable is, and how C# 7 features make implementing all of it mind blowing.

Programlama dillerinde en mühim OOP(Object Oriented Programing) strüktürlarından olan class mimarisına bakarak henüz basit düzeyde hizmetlemler gerçekleştirmemizi sağlayıcı ve belirli bir trup kısıtlamaları nezdinde çitndıran struct yapkaloriı C# diline özel ele alacağız.

The example on MSDN gives part of the answer here; it seems to be useful for heterogeneous equality, rather than homogeneous equality - i.e. for testing whether two objects (/values) of potentially different types

There is no need for an equality operator that accepts different types. That should hamiş even compile. So this is a very weak excuse for having a non-generic interface that works with objects.

Bunun katı saf, IStructuralComparable arayüzü, izlenceınızı daha modüler hale getirir ve kod yineını azaltır. Farklı done mimariları beyninde yapısal karşıtlaştırma alışverişlemlerini sessiz bir yerde yönetebilir ve kodunuzun bakımını kolaylaştırabilirsiniz.
