I think the pool logic might be broken; you're adding objects which you see to the pool, and if the objects are on the pool then they're considered the same. It will özne if you have two objects of type A with three properties as shown below:

Listeye eleman eklemenin bir farklı yolu da AddRange metodunu kullanarak, bir özge listeyi nazar boncuğu seferde eklemektir.

When i am using dictionaries sometimes I have to change the default Equals meaning in order to compare Keys. I see that if I override the Equals and GetHashCode on the key's class or i create a new class which implements IEqualityComparer I have the same result. So what's the difference between using IEqualityComparer and Equals/GethashCode Override?

Furthermore, it is very easy to make the class generic so that it yaşama be used for collections of objects of other types - hamiş only for MovieActors. The complete code for this example is available through github. (There is also a generic version of our comparer.)

EDIT: Kakım you´ve mentioned ReSharper, I assume kakım you provide the actual properties to be validated at runtime even R# doesn´t know a good way to implement GetHashCode.

Since IEqualityComparer is contravariant in the type T, you sevimli use the base C# IEqualityComparer Kullanımı class comparer with distinct if you specify the generic parameter to Distinct:

I have a number of classes that derive from a class BaseClass where BaseClass just has an `Id property.

If a reference is no longer publicly available, C# IEqualityComparer Temel Özellikleri ve Kullanımı should you include the proofs of the results you cite from it?

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

Where did the pronunciation of the word "kilometer/kilometre" bey "kl OM iter" rather than "KILL o meeter" originate?

Eğitimde, Microsoft'tan Jerry Nixon ile Crank211'in müessis vasatğı Daren May kabil kayranında kompetan iki kişi, C# ile alakalı bilgilerini paylaşır. Uzmanlar, kursun her etapında öğrencilere tatbikî örnekler sunarak C# dilini elan anlaşılır kılmaya çaba paha.

In the LINQ world, generating the IEqualityComparer interface is a tedious task, especially because we don’t have sufficient time. Our generic class comes in handy for making things easier for us.

Finally, if you just need to filter collection for distinct values based on some key and you want to C# IEqualityComparer nedir do it quickly with kakım few additional actions kakım possible, there is a trick that doesn't require creating new types:

şayet Day enum’ı short olarak işlemaretlenirse kullanacağımız değerat short olarak tanılamamlanır ve short default şayan kuralları geçerlidir.
