Can an anonymous type inherit from another type?

Question

According to the MSDN documentation on the StringComparer.OrdinalIgnoreCase property:

The OrdinalIgnoreCase property actually returns an instance of an anonymous class derived from the StringComparer class.

Is this a feature I'm unfamiliar with—anonymous types with inheritance? Or by "anonymous class" did the author simply mean "internal class deriving from StringComparer, not visible to client code"?

Answer 1

It's not an anonymous type in the normal C# meaning of the term.

It's just a type which is internal, so you don't know the name of it: you can't refer to the exact type within your code.
