An instance of the ReadOnlyCollection generic class is always read-only. 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 those changes. See Collection for a modifiable version of this class.

-ArrayList: Dizinin benzeridir lakin sadece object tipinden verileri saklar. Nedeniyle da gönderilen bilgi object değilse boxing çalışmalemine basıcı tutulur.

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

Hayat you arrange 25 whole numbers (derece necessarily all different) so that the sum of any three successive terms is even but the sum of all 25 is odd?

You want to use the yield keyword. You loop through the IEnumerable list and return the results with yeild. This allows the consumer to use the for each without modifying the collection.

Thous leads that your consumer classes are just awaiting interfaces instead of concrete classes and so you birey change the concrete implementation at a later stage without breaking your public contract (due to performance reasons use an List instead of a C# ReadOnlyCollectionBase Kullanımı LinkedList or vice versa).

After hopefully understanding your question, i think you have to distinguish between what you create and manage within your class and what you make available to the outside world.

It's not a concrete type like ReadOnlyCollection, so it doesn't tie you down to a specific implementation.

Important Some information relates to prerelease product that C# ReadOnlyCollectionBase Nasıl Kullanılır may C# ReadOnlyCollectionBase Nerelerde Kullanılıyor be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

However, the syntax is awkward. Adding an extension method birey simplify that syntax tremendously. Extension methods have at least three convenient features: The C# ReadOnlyCollectionBase Nasıl Kullanılır first is that they attach themselves to whatever classes you specify, automatically appearing in the IntelliSense dropdown lists for those objects; second, they're automatically passed whatever object they're called from birli their first parameter; third, when an extension method is used with a generic class (for instance, List), the method automatically figures out the veri type of the generic parameter.

This answer already assumes you want to return IEnumerable without any reasoning to support that decision.

This base class is provided to make it easier for implementers to create a strongly typed read-only custom collection.
