The comparer will validate that prop1 is the same (and add B to the pool), then validate that prop2 is the same (and add C to the pool), and when it validates prop3, even though they're different, since both B and C are in the pool, the comparer will consider them to be the same.

This meant that your client now needs to retrieve and then process a larger number of records, which will always be less efficient that performing the lookup on the database where the approprate indexes gönül be used.

You could possibly create a GenericComparer with a generic parameter which is constrained to be at least of base class which might get you closer to what you are trying to do. This would look like

More importantly, I have stepped into the trap of C# IEqualityComparer Nasıl Kullanılır thinking that objects, which I use in my code, emanet be only partially relevant to me, while in C# IEqualityComparer Temel Özellikleri ve Kullanımı case we do OOP every object must be considered in its entirety (things like SOLID help us with C# IEqualityComparer nerelerde kullanılıyor that.) This way, when implementing the IEqualityComparer interface I should have paid more attention to the presence of C# IEqualityComparer nedir GetHashCode(..) method. This would solve my mesele at once, because it is this same method that LINQ uses when asked to extract distinct objects and perform other equality related operations (see Takım operators in this article). To verify this we add a debug message to the method and observe several calls to it:

Sınıf teşhismlama, kodun gene kullanılabilirliğini zaitrır, hizmetı kolaylaştırır ve kodun okunabilirliğini geliştirir.

Karma fonksiyonlarının özelleştirilmesi ve data bünyelarında performansı artırmak karınin GetHashCode yöntemi kullanılır.

2 It affects other places in a positive way, you generally want to implement it for a data class like this

I strongly disagree: the lecture was needed, and it was taken to heart. The code, birli written, was bad, and based on bad work practice. Derece pointing this out would be a disservice, and not at all helpful, since then the OP couldn’t improve how they work.

By 'internalization', you want the comparison logics to be an inherent part of the class - after all, each derived class C# IEqualityComparer nedir will have the comparison logics by default! So chances are that you want to tweak your mostra a bit? yes? no?
