Arraylist vs List of type Object.

Question

Arraylist is just like a normal list which can store any value by upcasting the elements to "object" class. Can the same be done by declaring a generic list of type Object?
If so what's the advantage of one over the other?

Answer 1

ArrayList belongs to the days that C# didn't have generics. It's deprecated in favor of List<T>. You shouldn't use ArrayList in new code that targets .NET >= 2.0 unless you have to interface with an old API that uses it.
