C# ReadOnlyCollectionBase Provides the abstract base class for a strongly typed non-generic read-only collection.

If you're tolerant of some C# ReadOnlyCollectionBase Temel Özellikleri "noise" in your own encapsulated code then I would suggest wrapping a T[] array and exposing an IList which happens to be a C# ReadOnlyCollectionBase Kullanımı ReadOnlyCollection:
