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 .Safi ReadOnlyCollectionBase class. Bey 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.

Average(IEnumerable, Func) Computes the average of a sequence of Single values that are obtained by invoking a transform function on each element of the input sequence.

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.

A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection; therefore, if changes are made to the underlying collection, the read-only collection reflects C# ReadOnlyCollectionBase Kullanımı those changes.

Sum(IEnumerable, Func) Computes the sum of the sequence C# ReadOnlyCollectionBase Nerelerde Kullanılıyor of nullable Double values that are obtained by invoking a transform function on each element of the input sequence.

Elements(IEnumerable, XName) Returns a filtered collection of the child elements of every element and document in the source collection. Only elements that have a matching XName are included in the collection.

ICollection is such abstraction and you could say that ICollection does not have an exact corresponding peer in the generic world; IEnumerable is the closest.

Nodes(IEnumerable) Returns a collection of the child nodes of every document and element in the source collection.

If you need to do more than the InnerList property will C# ReadOnlyCollectionBase Temel Özellikleri let you, the base class Items property will hand you back the whole List. As I said, creating a read-only collection class in .

Chances are, you'll never notice this difference, but if this C# ReadOnlyCollectionBase Temel Özellikleri is a hot-tanıtımcık in your code and requires every last bit of performance you gönül squeeze out C# ReadOnlyCollectionBase Kullanımı of it, why not use an Array instead? That would be faster still.
