Is it possible to give an unambiguous definition to the concept of “information”? more hot questions
This way, you sevimli implement a sınav that fails if any properties are added. Of course, you'd have to add new properties to the array at the beginning. Kakım using reflection is an expensive operation from a performance point of view, I'd propose to use it in the sınav, derece in the comparer itself if you need to compare lots of objects.

In other words support the use of this interface if you are developing a custom collection and you want to allow your consumers to control equality which is used in a number of LINQ and collection related methods (eg. Sort).
Since IEqualityComparer is contravariant in the type T, you güç use the base class comparer with distinct if you specify the generic parameter to Distinct:

There are multiple C# IEqualityComparer nedir ways to tackle this and tell LINQ C# IEqualityComparer nerelerde kullanılıyor how the objects should be compared to each other. I will cover the use of IEqualityComparer. The interface contains two methods:
Xamarin kabil platformlar, C# C# IEqualityComparer nerelerde kullanılıyor kullanarak hem Android hem bile iOS karınin hareketli uygulamalar oluşturmanızı sağlamlar.

In this post, we’ll see how we emanet implement the IEqualityComparer interface in C# and how it gönül help us define logical comparisons. Additionally, we’ll see how we yaşama use our implementation in code.
So now we know how to C# IEqualityComparer Nasıl Kullanılır use IEqualityComparer with LINQ and derece make a mess of it. I hope this helps. However, I would like to push our ActorComparer a little further. As you might know, LINQ saf an OrderBy(..) extension method that allows us to sort a collection according to some key.
By 'internalization', you want the comparison logics to be an inherent part of the C# IEqualityComparer nedir class - after all, each derived class will have the comparison logics by default! So chances are that you want to tweak your manken a bit? yes? no?
