Notice that I didn't have to override Equals, GetHashCode in neither of the classes. I hayat use this comparer in any object that implements ICustom without having to rewrite the comparison logic.

If you change your class to implement IEquatable instead, the implementation of Distinct (which will use EqualityComparer.Default which in turn sees your type implements IEquatable and delegates to that) will work as you expect.

Basically you could check all the properties you want to check in Equals via reflection. To filter some of them out use an attribute on those properties:

Güç a unique position be deduced if pieces are replaced by checkers (can see piece color but not type)

is time to be happy. I’ve read this post and if I could I desire to suggest you few interesting things

Is there a preferred way of testing two instances of T for equality, or are there several equally valid ways?

It seems like a good rule. Let’s see C# IEqualityComparer nerelerde kullanılıyor how we birey implement the IEqualityComparer to make sure we güç work with collections of Player instances.

However, quite frequently we, C# programmers, use classes and want to get rid of duplicated objects in a collection the same way. Suppose, we do something with actors of a movie:

Dictionary’imizi oluştururken IEqualityComparer yardımıyla oluşturduğumuz Class’ın instance’sını ekliyoruz. Sonrasında Dictionary teker tekerlek gelen C# IEqualityComparer Kullanımı verilere bizim verdiğimiz algoritmaya göre bakıyor. Öncelik olarak oluşturduğumuz Class’da ki GetHashCode()’ a gidiyor oradan HashCode’u aldatmaıyor eğer önceki eklediği Key’lerde bu HashCode yoksa duraksız olarak eklemesini strüktüryor.
