and get a kaş of actors with unique last names. So we need a way to provide a key selector to our ActorComparer. This is done simply by creating a constructor that takes a function object birli an argument and stores it for further use:

Overriding Equals() from ValueType will do a C# IEqualityComparer Nasıl Kullanılır check for any object type, and it’s recommended this is overridden with any custom value type alongside implementing IEquatable.

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.

So now we know how to use IEqualityComparer with LINQ and not make a mess of it. I hope this helps. However, I would like to push our ActorComparer a little further. Birli you might know, LINQ saf an OrderBy(..) extension method that allows us to sort a collection according to some key.
