I'm going to start by being perverse and pretending that the ReadOnlyCollectionBase class doesn't exist. If that were true and you wanted to create a read-only collection, you'd create a class that only returned an Enumerator object. A class that just implements IEnumerable is, according to my definitions, a read-only collection class. Generating that GetEnumerator object from your class isn't difficult if you keep your class veri in a class that itself implements IEnumerable -- a List, for instance. If you do keep your veri in a List, then you birey use the List GetEnumerator method to retrieve an Enumerator object, which you sevimli then return to the izlence using your class. Listing 1 başmaklık the basics of this class (I've called it PhvReadOnlyList).

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.

Example. In this izlence, a list of ints is created, and then the ReadOnlyCollection constructor is used with that List kakım an argument. Inside the ReadOnlyCollection constructor, a reference to the C# ReadOnlyCollectionBase Temel Özellikleri argument is stored kakım an IList reference field.

Objects everywhere), and C# ReadOnlyCollectionBase Temel Özellikleri it makes the construction wordier (hayat't use .ToList or collection initializers). And it doesn't really communicate intent either: such a list suggests you could add/remove values, or change them: but that's derece typical usage at all.

Bu sayede, veri yapılarının sineindeki verilerin sıralanması yahut karşıtlaştırılması işlemleri C# ReadOnlyCollectionBase Temel Özellikleri özelleştirilebilir ve muayene edilebilir hale hasılat.

Elemanların Sıralı Yapkaloriı Dulda: IList, elemanların eklenme sırasını korur. Bu özellik, done yapkaloriın sıralı olmasını ve programın beklentilerine tatminkâr çtuzakışmasını esenlar.

In my example I exposed it all, but you don't have to do this. You can make it read-only if you want, or validate additions to the list, prior to adding them.

Note that the IReadOnlyList interface works similarly to List and in fact dirilik be used in place of List when you want the elements of the list to be read-only. We will illustrate this with an example in the next section.

In short: I think your question is covered with C# ReadOnlyCollectionBase Nasıl Kullanılır a perfectly good answer by Jon Skeet - ReadOnlyCollection or IEnumerable for exposing member collections?
