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

– Eric C# IEqualityComparer nedir Lippert Commented Apr 8, 2013 at 16:01 @EricLippert: What difficulties would arise if one allowed return type to be considered in method overloading only in cases where the return type was either being coerced to a particular type, or was passed to a method where all overloads of proper arity had C# IEqualityComparer Nasıl Kullanılır the same type for that parameter (e.
Implementing IEquatable only does a comparion between your object and which is most likely to be the same type. This is performed frequently with the new methods C# IEqualityComparer Kullanımı brought in alongside LINQ in 3.5. Overriding Equals() from ValueType will do a check for any object type, C# IEqualityComparer Temel Özellikleri ve Kullanımı and it’s recommended this is overridden with any custom value type alongside implementing IEquatable.
It looks like the generic version of this interface performs the same function but is used for Dictionary) collections.
Hepimiz Box Listemizi istediğimiz şeylere gereğince kategorize geçirmek istediğimiz bağırsakin kendimize bir C# IEqualityComparer nerelerde kullanılıyor kıstas belirlememiz gerekiyor bunu bizim muhtevain IEqualityComparer Interface’i örgüyor. Dictionary’imizi oluştururken IEqualityComparer sayesinde oluşturduğumuz Class’ın instance’sını ekliyoruz. Sonrasında Dictionary teker teker gelen verilere bizim verdiğimiz algoritmaya bakılırsa bakıyor. Öncelik olarak oluşturduğumuz Class’da ki GetHashCode()’ a gidiyor oradan HashCode’u aldatmaıyor eğer önceki eklediği Key’lerde bu HashCode yoksa doğruca olarak eklemesini örgüyor.
5 When writing programs in C# with the help of LINQ I have come across the IEqualityComparer generic interface several times.
