So easy, in fact, that I don't need a full column to do it (and if that's all you C# ReadOnlyCollectionBase Kullanımı want from this column, you kişi skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). What this topic does give me is C# ReadOnlyCollectionBase Nedir an excuse to talk about several things: how interfaces in .Kemiksiz 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.
