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

The sorun 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 uyanıklık etmenizi istiyorum. Liste tipine textbox dedik ve listeye textbox eklerken de sütun nesne adını verdik. şu demek oluyor ki text özelliğini felan vermedik. Kazık nesnenin kendisini verdik. Şimdi bu medarımaişetin yalabık doğrusu şu;

Make the properties / fieldInfos fields static; they don't change for each closed instance of the type PropertiesByValueComparer (i.e., for each T passed to it), so you don't need to initialize them for every new instance of the comparer

Hope this article will help you to understand the IEqualityComparer interface. Don't hesitate to write questions or suggestions.

The comparer will validate that prop1 is the same (and add B to the pool), then validate that prop2 is the same (and add C to the pool), and when it validates prop3, even though they're different, since C# IEqualityComparer nerelerde kullanılıyor both B and C are in the pool, the comparer will consider them to be the same.

Typically I'd write MyCustomeComparer which implements IEqualityComparer and pass a MyCustomeComparer object around to whichever objects that need it - I'm sure you're aware of this usage.

Bey we saw above, it doesn’t take much code. Kakım our paradigma evolves, we’ll likely have to extend our comparers, so C# IEqualityComparer nedir always thinking about what “equal” means now and what it could mean in the future is a valuable exercise.
