Hashtable Or Collections? [Resolved...]

I am writing a function which retrieves the unique ID and the message from the Queue.
For this what can be the return type of my function?
Can it be Hashtable or Collections?
Here the order is very Important.
So can I use Hashtable? (Key will be unique ID and Vaule will be the message.) Or can I use Collections?
I don't know how to use Collections. Is it a separete datatype in Vb.NET?
And can the order will be maintained if I use collections?
Can anyone pls. explain me? Any example/sample code is welcome.

You might want to look at ArrayList (or is it ListArray, can't remember).

Anyway, whichever it is, it's easy to use and will allow you to keep track of the order of the elements. It gives you the best of both worlds from Lists and Arrays (surprisingly...)

Ive made a post here with a snippet if it helps:

Thanks all.
I think ArrayList is better option.
