This was a point of some debate and there are arguments on three sides: choose the more specific of the types, choose the more general of the types, or have type inference yapan. I will derece rehash the whole argument but suffice to say that the "choose the more general" side won the day.
Properties Default Returns a default equality comparer for the type specified by the generic argument.

After inspecting multiple SO questions and answers related C# IEqualityComparer Temel Özellikleri ve Kullanımı to the topic birli well birli some other articles I have both found the solution that fitted my needs for the moment and C# IEqualityComparer Kullanımı got some understanding of the way IEqualityComparer is actually used by LINQ operators. Here I will try to explain what I got from there.
Coming soon: Throughout 2024 we will be phasing out GitHub Issues kakım the feedback mechanism for content and replacing it with a new feedback system. For more information see: .
Bey we can see, to satisfy the interface, we need to implement two methods: Equals and GetHashCode. Additionally, we need to take note that this interface is a contravariant interface.
The Equals(T, T) C# IEqualityComparer Nasıl Kullanılır method is reflexive, symmetric, and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if it is true for y and x; and true for two objects x and z if it is true for x and y and also true for y and z.
I strongly disagree: the lecture was needed, and it was taken to heart. The code, birli written, was bad, and based on bad work practice. Not pointing this out would be a disservice, and not at all C# IEqualityComparer Nasıl Kullanılır helpful, since then the OP couldn’t improve how they work.
Equals/GetHashCode derece only internalizes comparison logic, but also globalize them. There might be cases where C# IEqualityComparer Nasıl Kullanılır I would like internal comparison (not using collection) for just one time.
