Hi.
I have a question regarding the ArrayList.
In my code I use the arraylist to store objects of certain class.
I do not mix object types in the same ArrayList.

public ArrayList adresses = new ArrayList();

I store only objects from the class "CAdresses" in this ArrayList.
Now, every time I use the objects in the ArrayList I have to type cast them
into aCAdresses class type object since the compiler only knows it is a
object.
I want to declare the ArrayList so that it is known to the compiler which
type is stored in there so that I do not need the bulky syntax, and can use
intellisense.

Best regards, Jens
 
Hello,
Try to use
public List<CAdresses> adresses = new List<CAdresses>();

But this only works in C# 2.0. In 1.1. you have to cast ArrayList members to
class you need.

Best regards,
Andrew

In addition to what other have suggested about Generics in .NET 2.0, the
normal way to do this in .NET 1 was to derive your own collection class
from CollectionBase. Try looking at the MSDN docs for this class, I
think there's a template implementation there that you can use quickly
to create your own typed collection classes.
