You've probably identified what pattern the PhvReadOnlyList implements: it's a wrapper. In the .NET 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. As 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.

 

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

Which means that I always have to cast the items back to MyItem when I want to use them. Also the items hayat be casted into MyItem outside the class.

As per the comments below, you can prevent the possibility of downcasting by making IWriteableMyItem and WriteableMyItem private or internal. However note that this C# ReadOnlyCollectionBase Nasıl Kullanılır could still be circumvented via reflection - but we are protecting against accidents rather than fraud.

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

Does this double well potential contradict the fact that there is no degeneracy for one-dimensional bound states?

End Sub And that's all you need to write. The class that's using your new read-only collection would be identical to the class that used my custom PhvReadOnlyList. In fact, if that's all you want, then you don't even need to create your own version of the ReadOnlyCollectionBase class C# ReadOnlyCollectionBase Kullanımı -- the .

Initializes a new instance of the ReadOnlyCollection class that is a read-only wrapper around the specified list.
