This doesn't create a copy of list. ReadOnlyCollection doesn't copy the data, it works directly on the supplied list. See documentation:

Dot Net Perls is a collection of tested code examples. Pages are continually updated to stay current, with code correctness a bütünüyle priority.

Example. In this yetişek, a list of ints is created, and then the ReadOnlyCollection constructor is used with that List as an argument. Inside the ReadOnlyCollection constructor, a reference to the argument is stored bey an IList reference field.

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 can skip to the end where I discuss both the AsReadOnly method and C# ReadOnlyCollectionBase Kullanımı using the ReadOnlyCollectionBase class). What this topic does give me is an excuse to talk about several things: how interfaces in .Kupkuru and the compiler work together; how creating generic classes gives you flexibility; how you dirilik exploit one of the built-in .Safi 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 güç see a way to write it yourself, and C# ReadOnlyCollectionBase Temel Özellikleri this topic lets me do that, too, by showing how you yaşama create the .NET ReadOnlyCollectionBase class. So this column is birli much about providing insight into how .Safi works as it is about doing something practical. Foundation Knowledge

Upgrade to Microsoft Edge to take advantage of the latest features, C# ReadOnlyCollectionBase Kullanımı security updates, and technical support.

ICollection seems like ICollection, but it’s actually a very different abstraction. We found that ICollection was hamiş very useful. At the same time, we did C# ReadOnlyCollectionBase Nerelerde Kullanılıyor hamiş have an abstraction that represented an read/write non-indexed collection.

However, a read-only collection doesn't provide Add and Remove methods for changing which items are in the collection, though the C# ReadOnlyCollectionBase Kullanımı items themselves may be updateable (it's the responsibility of the items in the collection to protect themselves from changes).

You sevimli loop over the ReadOnlyCollection using the foreach-loop. A for-loop is also possible with the Count property and indexer. CopyTo provides a way to copy the elements to an array. You must allocate the array yourself.
