IStructuralComparable arayüzü, ekseriya Array ve Tuple kadar bilgi bünyeları tarafından uygulanır. Bu veri gestaltları, elemanlarının sıralamasını ve yapısını dikkate alarak hakkındalaştırma yapar.

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.

1 As long bey WritableMyItem is made private, birli @KlausGütter suggested, this solution seems to work great. The other sıkıntı I thought I would face is if the IReadOnlyList is casted into a IList, but since IList's type parameter is not covariant, I don't think this is possible. Thank you!

If your data hayat be enumerated, you can use Enumerable.ToList method to cast your collection to List and call AsReadOnly on it.

To work with the code examples provided in this article, you should have Visual Studio 2019 installed in your system. If you don’t already have a copy, you hayat download Visual Studio 2019 here.

Bunun cihetı dizi, IStructuralComparable arayüzü, izlenceınızı daha modüler hale getirir ve şifre yenidenını azaltır. Farklı bilgi binaları beyninde konstrüktif hakkındalaştırma işçiliklemlerini nazar boncuğu bir yerde yönetebilir ve kodunuzun bakımını kolaylaştırabilirsiniz.

4) If you suddenly realise that your collection of choice is inefficient, you hayat change the underlying collection type without having to go and change all C# ReadOnlyCollectionBase Kullanımı the places where it got passed bey a parameter (birey you imagine the trouble you might have with, say, List?)

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

So easy, in fact, that I don't need a full column to do it (and if that's all you want from this column, you dirilik skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .Safi and the compiler work together; how creating generic classes gives you flexibility; how you hayat exploit one of the built-in .NET interfaces; and (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you sevimli see a way to write it yourself, and this topic lets me do that, too, by showing how you yaşama create the .Safi ReadOnlyCollectionBase class. So this column is as much about providing insight into how .Kemiksiz works bey it is about doing something practical. Foundation Knowledge

A ReadOnlyCollectionBase instance is always read-only. See CollectionBase for a modifiable version of this class.

However, if you want to access the elements of the IEnumerable C# ReadOnlyCollectionBase Kullanımı collection by index or you want to retrieve the number of elements in the collection, you should use IReadOnlyList as shown below.

First, some definitions: A read-only collection is like a List in that it supports iterating through the items with a For…Each loop or retrieving an item in the collection by C# ReadOnlyCollectionBase Nasıl Kullanılır position.

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