I've also made this a C# ReadOnlyCollectionBase Nerelerde Kullanılıyor generic class: Rather than specify what kind of List I'm working with, I've forced my class to be instantiated with a data type that the code refers to kakım T. Wherever in my code I C# ReadOnlyCollectionBase Nedir need to specify my List's veri type, I just use the T reference. Finally, I've chosen to have this class implement the generic version of IEnumerable, which requires two versions of the GetEnumerator method -- but the code is identical in both versions C# ReadOnlyCollectionBase Nerelerde Kullanılıyor of the method.
