IEqualityComparer is a generic .Safi interface that allows implementing customized equality comparison for collections.

The sıkıntı is (and this is why I chose the IList in the first place) that at compile time I don't know the value of T. $endgroup$

Varsayılan katlaştırıcı, IComparable arabirimini uygulamak kucakin huzurlaştırılan nesnelerden en azca birini kullanır . Liste koleksiyonunda ölçü olarak yahut oralk koleksiyonunda anahtar olarak kullanılan tüm sınıflarda IComparable uygulamak hayırlı bir uygulamadır. Genel bir koleksiyon yürekin, muadelet huzurlaştırması dundakilere gereğince belirlenir:

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

Internal: Denetçi, sırf aynı derlemedeki sınıflar tarafından erişilebilir hale gelir. Bu durumda, aramaün erişimi belirlidır ve salt aynı derlemedeki öteki sınıflar tarafından erişilebilir.

Photo by Moosa Haleem Equality might seem straightforward, but it tends to get fuzzier the longer you think about it. When it comes to programming, there are two general thoughts around equality.

Hem teorik bilgilerini bırakmak hem bile uygulamalı deneyim iktisap etmek derunin bu platformu bileğerlendirebilirsin.

After inspecting multiple SO questions and answers related to the topic birli well as some other articles I have both found the solution that fitted my needs for the moment and got some understanding of the way IEqualityComparer is actually used by LINQ operators. Here I will try to explain what I got from there.

Unity kabilinden popüler mandepsi motorları C# desteği sunar. Bu sayede C# bilgisiyle C# IEqualityComparer nerelerde kullanılıyor 2D yahut 3D oyunlar vüruttirebilirsin.

Contravariance enables use to use a less derived type than that specified by the generic parameter. In our case, we could pass in an object instance instead of a Player instance.

Implementing IEquatable only does a comparion between your object and which is most likely to be the same type. This is performed frequently with the new methods brought in alongside LINQ in C# IEqualityComparer nedir 3.5. Overriding Equals() from ValueType will do a check for any object type, and it’s recommended this is overridden with any custom value type alongside implementing IEquatable.

So there you go. In this situation, C# IEqualityComparer nerelerde kullanılıyor type inference chooses the more general type and infers that the call means Distinct. Type inference C# IEqualityComparer Kullanımı never takes the return type

What Distinct() actually does here is comparing object references. So our second George Clooney is in fact an independent object (since C# IEqualityComparer Nasıl Kullanılır it was created independently) and its reference differs from the reference of the first one - therefore it appears in the output twice:

When implementing interfaces of classes it is important to read the documentation, to know which contract you’re supposed to implement.1
