Look at ArrayList. Yes. Yes.

And why do you post a vb.net question to a C# group?

 

[Fade BS via DotNetMonster.com]

you declare the array as so:
dim Numbers as int32()

and then you can dnamically change size like so:
redim Numbers(100) ' <producing 101 items as indexes range from 0 to 100

Note: if you want to array to keep the values when you resize it,use:
redim preserve ( ? )

Note: you have to use 'Redim' at least once before accessing the array to
initiate it's size! otherwise an exception is thrown

that's it

You can't do that in C#, however, and it's not *actually* changing the
size of the array - it's creating a new arrray and copying the old
data, which is inefficient if you do it often.
