My code is littered with collections - derece an unusual thing, I suppose. However, usage of the various collection types isn't obvious nor trivial. Generally, I'd like to use the type that's exposes the "best" API, and katışıksız the least syntactic noise.

dictionaries). Bey it turns out, many lists are never changed, or at least never extended. Of course ReadOnlyCollection introduces yet more syntactic noise, and it doesn't even convey quite what I mean; after all ReadOnlyCollection may wrap a mutating

I was thinking about creating a new class derived from ReadOnlyCollection (class ReadOnlyMyCollection : ReadOnlyCollection or class ReadOnlyMyCollection : ReadOnlyCollection) which returns the read-only wrapper class (ReadOnlyMyItem) through the square brackets operator, but either the square brackets operator is derece marked as virtual and the return type is derece even the same or the constructor doesn't have an IList of the wrapper class (IList) to use. Should I build the class (ReadOnlyMyCollection) from scratch?

Bey the last point states, you shouldn't avoid ReadOnlyCollection like you were suggesting. It is a very useful type to use for public members to inform the consumer of the limitations of the C# ReadOnlyCollectionBase Nerelerde Kullanılıyor collection they are accessing.

Passing IList/IDictionaries is generally no good because I hayat't communicate nor enforce the read-only nature of those views (so e.g. IList is actively worse than an array here)

Nothing wrong with wordy types for major API's with small surfaces, but hamiş as a general practice inside a large codebase.

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