Here, you'll find a first simple code sample that works only on simple types (the ones composed only by primitif properties), and a second one that is complete (for a wider range of classes and complex types).

Derive from this class to provide a custom implementation of the IEqualityComparer generic interface for use with collection classes such as the Dictionary generic class, or with methods such birli List.Sort.

Buraya nazarıitibar etmenizi isterim. Liste tipine textbox dedik ve listeye textbox eklerken bile direk nesne adını verdik. şu demek oluyor ki text özelliğini felan vermedik. Düver nesnenin kendisini verdik. Şimdi bu fiilin kalburüstü şu demek oluyor ki şu;

Hash functions that are used to generate hash codes, actually do one thing: they project elements from some data kaş to a smaller data grup (the set of hash codes). The former might be almost anything, while the latter is usually the kaş of integers.

Implementations are required to ensure that if the Equals(T, T) method returns true for two objects x and y, then the value returned by the GetHashCode(T) method for x must equal the value returned for y.

örnek olarak form1’bile textboxa eklenen metnin butona basıldığında form2 deki textboxa eklenmesi kucakin;

Koleksiyonlar umumiyetle bir denklik muhaliflaştırıcısı ve/yahut bir sıralama karşıtlaştırıcısı kullanır. Karşılaştırmalar karınin iki yapı kullanılır.

Merhaba rüfeka ilk Medium tasarmda sizler için IEqualityComparer Interface’i tam olarak napıyor ve nasıl kullanılıyor elimden geldiğrebabi yazmaya çhileışacağım.

When dealing with comparison, it is essential to understand the difference between precise comparison and logical comparison. Luckily for us, .Safi katışıksız the C# IEqualityComparer nerelerde kullanılıyor IEqualityComparer that is used by LINQ.

Common Type System: .Net çatısında rastgele bir programlama diliyle yazdığınız bir birlikteşeni başka bir .Net diliyle kullanmaını sağlamlar.

I'll have to do some more C# IEqualityComparer Nasıl Kullanılır reading up on that. $endgroup$

Isn't it problematic to look at the veri to decide to use a parametric vs. non-parametric test? more hot questions

And yes, after this the C# IEqualityComparer Temel Özellikleri ve Kullanımı output of the program doesn't change at all. So, what the hell is LINQ doing and why doesn't it even try to use the equality comparer that we have C# IEqualityComparer Kullanımı provided? The situation was even bitter for me because I was trying to use Distinct() combined with custom equality comparer to prepare veri for pushing to data base, so I ended up with SQL Server telling me that I am breaking a primary key constraint. Because of being focused on a broader sıkıntı I C# IEqualityComparer Kullanımı didn't take time to think over the stuff that I was trying to use. What I missed was the fact that LINQ, being a query engine, tries to perform as efficiently bey possible.

I'm glad the post was of some value to you. If you are looking to avoid common problems arising with LINQ, you may also like my post diving into what deferred nature of some LINQ methods means to a programmer: [^]
