Kakım far as best practices around using this interface for your own purposes. I would say that the best practice would be to use it when you are deriving or implementing a class that özgü similar functionality to the above mentioned .

Bir çok zeban kadar C# da bize enum tasarrufı kucakin keyword katkısızlar ve “enum” bizlere özelleştirelebilir enum sınıfları tanılamamlamımıza yardımcı evet.

Well, your implementation is pending. You implemented custom comparer for IEnumerable but forgot to implement the same for KeywordSchedule.

I would say that the best use would be when you need to plug in different equality rules for a certain algorithm. Much in the same way that a sorting algorithm might accept an IComparer, a finding algorithm might accept an IEqualityComparer

Finally, if you just need to filter collection for distinct values based on some key and you want C# IEqualityComparer Kullanımı to do it quickly with as few additional actions birli possible, there is a trick that doesn't require creating new types:

If things don't seem to be working (such bey duplicate key errors when doing ToDictionary) put a breakpoint inside Equals to make sure it's being hit and make sure you have GetHashCode defined (with override keyword).
