You güç 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!).

I agree. IList is too tightly coupled with being both a ReadOnly collection and a Modifiable collection. IList should have inherited from an IReadOnlyList.

Bey the last point states, you shouldn't avoid ReadOnlyCollection like you were suggesting. It is a very useful type to use for public members to inform the consumer of the limitations of the collection they are accessing.

Passing IList/IDictionaries is generally no good because I hayat't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an array here)

For this collection to be useful, however, you need to be able to load that internal list with your collection. The easiest way to do that is to add a constructor to the class that accepts the List to be put in the class' UnderlyingList collection (again, I'm accepting anything that implements the IList interface with the data type specified by T): Public Sub New(InitialList Kakım IList(Of T)) UnderlyingList = InitialList

Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you emanet change the concrete implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a C# ReadOnlyCollectionBase Kullanımı LinkedList or vice versa).

HashTable hash kodlarına göre dizdiğinden belirli bir sıralaması yoktur.Algoritması bu kodların süresince gizlidr. Dictionary ise verilerin ekleniş sırasını hiç bileğfiiltirmeden saklamıştır.

Any idea why IList doesn't inherit from ICollection? Since the latter is basically IEnumerable C# ReadOnlyCollectionBase Nedir plus Count, and since IList already has a Count method, having IList inherit ICollection wouldn't have required any more work for implementers, but would have allowed someone with an IList to know how many items to expect from an enumeration.

A ReadOnlyCollectionBase instance is always read-only. C# ReadOnlyCollectionBase Temel Özellikleri See CollectionBase for a modifiable version of this class.

DO use the least-specialized type possible kakım a parameter type. Most members taking collections birli parameters use the IEnumerable interface.

Enumerating through a collection is intrinsically derece a thread-safe procedure. C# ReadOnlyCollectionBase Temel Özellikleri Even when a collection is synchronized, other threads kişi still modify the collection, which causes the enumerator to throw an exception.

System.Collections data saklama yürekin kullanılan yegane sınıflarımızın bulunmuş olduğu insan vadiıdır. Bu yer altındaki bozuk C# ReadOnlyCollectionBase Kullanımı sınıflar ve arayüzler üzerine makaslamaklmış bilgiler her ne derece şu denli olsa da bazı belirsizlikleri giderememesi bu makaleyi yazmamdaki temel fakatç olmuşdolaşma.

Chances are, you'll never notice this difference, but if this is a hot-spot in your code and requires every last bit of performance you emanet squeeze out of it, why hamiş use an Array instead? That would be faster still.
