Also it is unclear why GetHashCode takes only value properties into account. Even though it will definitely work but looks a little bit strange. Maybe you should add a comment why class properties

I'd also suggest small refactoring of FamilySelector class. Currently it holds the data and performs comparison. Usually implementation of IEqualityComparer is a veri-less class that just performs a comparison:

int’ e cast ederek bizim derunin anlamlı bir dijital bileğerlere ulaşabiliriz. Yalnızca numerik ayar de bileğil eğer ki Day tipini kod içerisinde kullanırsak bize henüz geniş elastikiyet esenlayabilme potansiyiline sahiptir.

Because you need an instance and not just a method call you kişi't let the generic type be inferred by the compiler (see this discussion) but have to do so when creating the instance:

EDIT: As 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.

in the constructor, there is no point to store properties in this case at all and you yaşama avoid executing reflection and linq again and again for each GetValueProperties call.

I would say that the best use would be when you need to plug in different equality rules for a certain algorithm. Much in the same way that a sorting algorithm might accept an IComparer, a finding algorithm might accept an IEqualityComparer

 In the plain case, when we need to drop only exact duplicates, the simple Distinct() call C# IEqualityComparer nerelerde kullanılıyor will do. The simplest possible example is getting unique integers from a collection of numbers:

So what happens when it comes time to actually deduce the type argument? We have two candidates: Position and C# IEqualityComparer Temel Özellikleri ve Kullanımı BaseClass. Both satisfy the stated bounds. Position satisfies the first bound because it is identical to the first bound, and satisfies the second bound because C# IEqualityComparer Kullanımı it is smaller than the second bound.

I've tried using LINQ SequenceEqual but again bey the instances C# IEqualityComparer nedir of T are different this returns false;

comparing two objects for values without listing every column See more linked questions Related

However, quite frequently we, C# programmers, use classes and want to get rid of duplicated objects in a collection the same way. Suppose, we do something with actors of a movie:

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

The result is the same kakım when using the first version of ActorComparer, although the new one is much more flexible in the sense that it may be used differently in different contexts and no further C# IEqualityComparer Kullanımı modifications are required to its code.
