Class with in a class

[WJProctor]

Hi there, im having a little problem. I have a class (Box) and a Class (Item). Obviously a box can have items. I would idealy like to be able to say:

Box.Item(1).Name = Item1
Box.Item(2).Name = Item2

And so on. How would i code this, i cant seem to work it out, ive tried all sorts and run out of ideas. Could any body point me in the right direction or tell me where i could find out more about this.

Thanks

The easy way is to add a ArrayList or HashTable collection to your box class and use it to hold your Item objects.

The more correct way is to define a new class that inherits from CollectionBase is called Items (plural). It has an Item method (part of the CollectionBase) that returns an Item object (as opposed to the default Object which isn't typesafe). Take a look at how the framework does it -- it defines a Form object that contains an collection object named Controls, which contains items of type Control.
