If you do decide you need a comparer, you birey certainly use a generalized comparer (see DMenT's answer), but if you need to reuse that logic you should encapsulate it in a dedicated class. You could even declare it by inheriting from the generic base:
The sorun is (and this is why I chose the IList in the first place) that at compile time I don't know the value of T. $endgroup$
Besides, it allows to use more than one property as a key, so the next call is absolutely valid and will preserve all actors with the same last name as long birli their first names differ:
next, when we iterate over the query object it gets hash code for each item in the source collection and compares it with the hashes of preceding objects
This interface allows the implementation of customized equality comparison for collections. That is, you hayat create your own definition of equality, and specify that this C# IEqualityComparer nedir definition be used with a collection type that accepts the IEqualityComparer interface.
Therefore, when testing two instances of T for equality, because C# IEqualityComparer nerelerde kullanılıyor T saf no internal understanding of equality, you will have to make an explicit choice of a IEqualityComparer instance which performs the sınav according to your specific requirements.
