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

The problem 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. $endgroup$

Buraya ilgi etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de kazık nesne adını verdik. Kısaca text özelliğini felan vermedik. Sütun nesnenin kendisini verdik. Şimdi bu sorunin görklü kısaca şu;

If there is only one way of testing two instances of T for equality, or if one of several methods is preferred, then IEquatable would be the right choice: This interface is supposed to be implemented only by T itself, so that one instance of T has internal knowledge of how to compare itself to another instance of T.

EDIT: Kakım 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.

The second form is logical equality. Anyone who başmaklık worked with databases understands the idea of identifiers and their use case for distinguishing sameness. Developers define reasons for equality in code, but the logic yaşama be composed of smaller precise equality comparisons.

For me it seemed that LINQ simply ignored my equality comparer C# IEqualityComparer Nasıl Kullanılır and kept doing everything on its own. In fact, we could check this by adding a debug output to Equals method:

players: khalidabuhakmeh and nicoleabuhakmeh. Our next step is to implement the IEqualityComparer. Let’s first look at the interface itself.

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.

Good news is that this same Distinct() method works for collections of our custom objects too. So if George Clooney accidentally creeps into our collection twice that's derece a mesele:

If the code is so hard C# IEqualityComparer nedir to analyze that you have to write a backtracking algorithm to get it right, odds are good that the code should be written more clearly in the C# IEqualityComparer nedir first place. If the compiler gönül't make sense of it without backtracking, neither emanet the human reader.
