You get a nice simple bool Equals(T other) function and there's no messing around with casting or creating a separate class.
ちょっと横道にそれますが、上記サンプルコード（構造体の例など）にちょっと見慣れない形式のコードがいくつか見受けられます。
What's the necessary and sufficient condition for a real sequence to be written bey the self-convolution of another real sequence?
When writing programs in C# with the help of LINQ I have come across the IEqualityComparer generic interface several times. The name conveys the purpose of the interface clearly, still, surprisingly, my first attempts to apply it were marked by strong confusion - the thing merely didn't work the way I wanted it to. Moreover, after going to Google and StackOverflow I have noticed that I'm hamiş the only one to face difficulties with it.
The first is the idea of precise equality. Given two references to objects, do the two references point to the same location in memory? Programming languages are suited for this kind of comparison, and .NET comes with many prebuilt operators to handle this case.
Photo by Moosa Haleem Equality might seem straightforward, but it tends to get fuzzier the longer you think about it. When it C# IEqualityComparer Temel Özellikleri ve Kullanımı comes to programming, there are two general thoughts around equality.
Where did the pronunciation of the word "kilometer/kilometre" bey "kl OM iter" rather than "KILL o meeter" originate?
We’ll write a classic implementation of IEqualityComparer class. In our example, we C# IEqualityComparer Temel Özellikleri ve Kullanımı need to compare customers. Two customers are distinct if your first char Name is different.
To enhance all these software-related activities I maintain a blog writing there on various topics, most of which actually come back to programming.
Contravariance C# IEqualityComparer nerelerde kullanılıyor enables use to use a less derived type than that specified by the generic parameter. In C# IEqualityComparer nerelerde kullanılıyor our case, we could pass in an object instance instead of a Player instance.
He o yardımcı Description attribute bizim alınmıza çıkar. Bu attribute ile ne enum elamanının niçin var bulunduğunu , ne muhtevain bu değere sahip bulunduğunu kıytırıkçe tanımlayabiliriz ve bu description’a erişebiliriz.
Öte taraftan Tutorials Teacher, LINQ'den Node.js'ye kadar çeşitli alanlarda kendini vüruttirebileceğin eğitimler bile sunar. İlgili geniş yelpaze, programlama yolculuğunda ihtiyacın olan her konuda koltuk alabileceğin fehvaına hasılat.
The same goes for the LINQ operators that accept a comparer. But again, always consider if the equatable behavior that should be intrinsic to the class rather than defined externally.
