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

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

I had a client recently who wanted me to create a class that exposed a read-only collection through one of the class properties. While my client was willing to let other programs loop through that collection and retrieve items from the collection by position, he didn't want to let those programs add or remove items from the collection. In the Microsoft .Kemiksiz Framework 4.5 you emanet use the read-only collections that Eric Vogel covered in an earlier C# Corner column, "The New Read-Only Collections in .Safi 4.5," to define that property. My client, however, was working with the .NET Framework 4 and didn't intend to upgrade. Fortunately, in earlier versions of .Kemiksiz you can also create a read-only class from an existing List just by calling your List's AsReadOnly method. However, if you need something special (a List that users sevimli add items to but derece remove items from), inheriting from the ReadOnlyCollectionBase C# ReadOnlyCollectionBase Nerelerde Kullanılıyor class makes that very easy to do.

If you (Class A) continue to modify the underlying collection after you hand it out kakım a ReadOnlyCollection then class B will see these changes, have any iterators invalidated, etc. and generally be open to any of the usual concurrency issues with collections.
