You hayat argue that you may be able to downcast IPerson to Person, but at this point I would answer telling you that you need to follow your own coding conventions: if you defined that you never return Person but IPerson then I would do it this way in the entire code base, and if you need a write-capable Parents property, then you return Person instead (and you avoid a cast later!).

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 yaşama skip to the end where I discuss both the AsReadOnly method and using the ReadOnlyCollectionBase class). C# ReadOnlyCollectionBase Nerelerde Kullanılıyor What this topic does give me is an excuse to talk about several things: how interfaces in .NET and C# ReadOnlyCollectionBase Nedir the compiler work together; how creating generic classes gives you flexibility; how you kişi exploit one of the built-in .Kupkuru interfaces; and C# ReadOnlyCollectionBase Kullanımı (finally) how to simplify ugly syntax by building your own extension methods. I also think that you don't really understand anything unless you birey see a way to write it yourself, and this topic lets me do that, too, by showing how you hayat create the .Kupkuru ReadOnlyCollectionBase class.
