IEqualityComparer is a generic .NET interface that allows implementing customized equality comparison for collections.
I'd also suggest small refactoring of FamilySelector class. Currently it holds the data and performs comparison. Usually implementation of IEqualityComparer is a veri-less class that just performs a comparison:
Besides, it allows to use more than one property birli a key, so the next call is absolutely valid and will preserve all actors with the same last name bey long kakım their first names differ:
I've added to my class the IEqualityComparer implementation, not sure if the code bellow is the correct one, especially the Equals(object x, object y) functions: should we override or make a new implementation of the Equals method, like this: ?

Where did the pronunciation of the word "kilometer/kilometre" as "kl OM iter" rather than "KILL o meeter" originate?
Yaşama a unique position be deduced if pieces C# IEqualityComparer Kullanımı are replaced by checkers (kişi see piece color but derece type)
So what happens when it comes time to actually deduce the type argument? We have two candidates: Position and BaseClass. Both satisfy the stated bounds. Position satisfies C# IEqualityComparer Nasıl Kullanılır the first bound because it is identical to the first bound, and satisfies the second bound because it is smaller than the second bound.
Contravariance enables use to use a less derived type than that specified by the C# IEqualityComparer nerelerde kullanılıyor generic parameter. In our case, we could pass in an object instance instead of a Player instance.
Birli we güç see, to satisfy the interface, C# IEqualityComparer nerelerde kullanılıyor we need to implement two methods: Equals and GetHashCode. Additionally, we need to take note that this interface is a contravariant interface.
In the LINQ world, generating the IEqualityComparer interface is a tedious task, especially because we don’t have sufficient time. Our generic class comes in handy for making things easier for us.
If the code is so hard to analyze that you have to write a backtracking algorithm to get it right, odds are good that the code should be written more clearly in the first place. If the compiler dirilik't make sense of it without backtracking, neither yaşama the human reader.
making the lambda expression optional C# IEqualityComparer nerelerde kullanılıyor in the constructor so that full object equality emanet be checked by default, not just on one of the properties.
