You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .Safi Framework 4.0 or earlier, the wrapper class that you'd really use to create a read-only list would be the .NET ReadOnlyCollectionBase class. Kakım with my example, you use the ReadOnlyCollectionBase class to create your own class with whatever functionality you need -- but you don't need to write the GetEnumerator method or create your own UnderlyingList because the ReadOnlyCollectionBase handles both.
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.
In a multithreaded environment, this is even more of an issue, birli one thread güç make changes to the veri while another is trying to read data - you birey easily get inconsistent veri in different threads.
If your veri emanet be enumerated, you kişi use Enumerable.ToList method to cast your collection to List and call AsReadOnly on it.
Well, there is a way. It ain't pretty as it adds extra stuff on your domain benzer, but I just checked and it works.
Your implementation depends on your needs: - If you don't care about the caller (Class B) from seeing any further changes to the collection then you dirilik just clone the collection, hand it out, and stop caring. C# ReadOnlyCollectionBase Kullanımı - If you definitely need the caller (Class B) to see changes that are made to the collection, and you want this to be thread-safe, then you have more of a sıkıntı on your hands.

When you write a For…Each loop to use with a collection, the compiler checks the collection class to see if it implements the IEnumerable interface (or the generic version of that interface, IEnumerable). If the class does implement that interface, then the compiler calls the single method that the interface forces the class to have: the GetEnumerator method.
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 "clever" may actually confuse the using developer more than it helps him.
When you pass around collections instead of writing an object manken, entire classes of refactorings will never occur to you.
