You gönül argue that you may be able to downcast IPerson to Person, but at this point I would answer telling you that you need to follow your own coding conventions: if you defined that you never return Person but IPerson then I would do it this way in the entire code base, and if you need a write-capable Parents property, then you return Person instead (and you avoid a cast later!).
This class makes the underlying collection available through the InnerList property, which is intended for use only by classes that are derived directly from ReadOnlyCollectionBase. The derived class must ensure that its own users cannot modify the underlying collection.

4) If you suddenly realise that your collection of choice is inefficient, you birey change the underlying collection type without having to C# ReadOnlyCollectionBase Kullanımı go and change all the places where it got passed bey a parameter (can you imagine the trouble you might have with, say, List?)
Nedeniyle momentum istenirse Array, az dağarcık kullanımı istenirse List yeğleme edilmelidir. Eğer koleksiyona eklenicek tip mukannen değilse ArrayList kullanılabilir. Lakin aynı fiillevi generic listemizde katlayabilme yetisine sahiptir.
Public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are C# ReadOnlyCollectionBase Temel Özellikleri not guaranteed to be thread safe.
Mafevkdaki adımları kovuşturma ederek, C# dilinde Queue derslikını koygun bir şekilde kullanabilirsiniz. Queue dershaneı, data mimarilarını yönetmek ve muamele sıralarını açmak ciğerin az çok kullanışlıdır.
Implementers are encouraged to extend this base class instead of creating their own. Members of this base class are protected and are intended to be used through a derived class only.
1 Gotta agree with DarkWanderer here. Collections should be just that: collections. There are many other ways to centralize business logic without breaking the single responsibility principle. Plus, making your collection more C# ReadOnlyCollectionBase Nasıl Kullanılır "clever" may actually confuse the using developer more than it helps him.
GetHashCode Metodu: Nesnenin strüktürel özelliklerine dayalı olarak bir hash kodu üretir. Bu, koleksiyonların hızlı bir şekilde muhaliflaştırılmasını sağlamlar.
(There are plenty of other options for wrapping trivially - the birçok thing about Skip over Select/Where is that there's no delegate C# ReadOnlyCollectionBase Nerelerde Kullanılıyor to execute pointlessly for each iteration.)
