" which of course is inferred in the selected answer. MSDN also recommends inheriting EqualityComparer instead of implementing the interface "because EqualityComparer tests equality using IEquatable
Enum’ı kesinlikle yazdığımız projelerde kullanmışızdır. Muta dipında bazı alanları öngörebiliriz.Bu alanlar mukannen bir mesabe kümesine sahiptir. Bunları bilgi analizindeki kategorik verilere benzetebiliriz ve alanların alabileceği değefrat önceden belirlidir, sabittir ve degajeletilebilir. Bu gestalt enum ile daha okunabilir şifre yazmamızı ve bu numerik değerlerin ne derk geldiğini anlamamızı olanak sağlar.
IEqualityComparer is an interface which is used to find whether an object is equal or hamiş. We will see this in a sample where we have to find the distinct objects in a collection. This interface will implement the method Equals(T obj1,T obj2).
EDIT: Bey you´ve mentioned ReSharper, I assume birli you provide the actual properties to be validated at runtime even R# doesn´t know a good way to implement GetHashCode.
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 C# IEqualityComparer nerelerde kullanılıyor you expect.

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 not a C# IEqualityComparer Kullanımı sorun:
I strongly disagree: the lecture was needed, and it was taken to heart. The code, as C# IEqualityComparer nedir written, was bad, and based on bad work practice. Derece pointing this out would be a C# IEqualityComparer Nasıl Kullanılır disservice, and hamiş at all helpful, since then the OP couldn’t improve how they work.
On the other hand, if a dictionary will be used to hold and look up int[] values, each of which will be the only reference anywhere in the universe to an instance of int[], and if none of the instances will be modified nor exposed to outside code, it may be useful to regard birli equal array instances which hold identical sequences of values. Since Array.Equals tests for strict equivalence (reference equality), it would be necessary to use some other means of testing the arrays for equivalence.
