I do derece pass around Listss if I birey possibly help it. Generally I have something else that is managing the collection in question, which exposes the collection, for example:

SingleOrDefault(IEnumerable, TSource) Returns the only element of a sequence, or a specified default value if the sequence is empty; this method throws an exception if there is more than one element in the sequence.

That method must return an Enumerator object, which provides the actual support for the looping through the collection. Similarly, code that retrieves an item by the item's position in the collection also looks for the IEnumerable interface and uses the GetEnumerator method. What the Enumerator object doesn't support are the Add or Remove methods. Ignoring the ReadOnlyCollectionBase

Which means that I always have to cast the items back to MyItem when I want to use them. Also the items kişi be casted into MyItem outside the class.

Imagine we have existing sistem with Organization => Employees already grup up. To apply this technique, we need to change Organization benzer a bit:

If you do this then there's nothing stopping your callers casting the IEnumerable C# ReadOnlyCollectionBase Kullanımı back to ICollection and then modifying it. ReadOnlyCollection removes this possibility, although it's still possible to access the underlying writable collection via reflection.

ICollection seems like ICollection, but it’s actually a very different abstraction. We found that ICollection was derece very useful. At the same time, we did not have an abstraction that represented an read/write non-indexed collection.

Inheriting from a non-generic base class would be ineffecient. If the type was using a non-generic base, all it would be would be a thin layer above the base collection, where the generic features would simply derive from casting from the underlying object instances of the base collection.
