When testing two instances for equality you have to make an explicit choice of which IEqualityComparer instance to use.

1 Foo should be immutable if you intend to use it kakım key in hash tables. An in that case new properties needs to be seki using the ctor's paramsters, and anyone doing so would see that your test for the Comparer no longer compiles.

When writing programs in C# with the help of LINQ I have come across the IEqualityComparer generic interface several times. The name conveys the purpose of the interface clearly, still, surprisingly, my first attempts to apply it were marked by strong confusion - the thing merely didn't work the way I wanted it to. Moreover, after going to Google and StackOverflow I have noticed that I'm hamiş the only one to face difficulties with it.

According to the IEqualityComparer code example provided by microsoft, you will want to use the new keyword (so hiding the Equals implementation of the object) for implementing Equals.

You could be passing, via extension method, a ReadOnlyCollection and they would still be able to evaluate through it. They cannot, then, alter the original collection, because the original collection could be written in any number of ways.

In C# IEqualityComparer Nasıl Kullanılır 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.

It looks like C# IEqualityComparer nerelerde kullanılıyor you're forgetting the immutable nature of IEnumerable. None of the LINQ methods actually change the original variable.
