Regardless of what type of array you?re working with, the array identifier is actually a handle to a true object that?s created on the heap. The heap object can be created either implicitly, as part of the array initialization syntax, or explicitly with a new expression. Part of the heap object (in fact, the only field or method you can access) is the read-only length member that tells you how many elements can be stored in that array object. The ? []? syntax is the only other access that you have to the array object.
