adding items to an arrayList

[Darrel]

I'm trying to grab the files in a directory and add each one to an array
list. Thist is what I have:

1 Dim filesToUpload() As ArrayList
2 Dim batchFiles As String() =
System.IO.Directory.GetFiles(Server.MapPath("/batchupload/"))
3 Dim arrayCount As Integer = 0
4 For Each fileName As String In batchFiles
5 filesToUpload(arrayCount).Add(fileName)
6 arrayCount = arrayCount + 1
7 Next

But it's giving me an 'Object reference not set to an instance of an
object.' error on line 5. This is code from a tutorial (though modified to
use an arrayList rather than rediming an array) so I'm assuming I goofed up
my syntax somewhere.

I think you need

dim files as ArrayList
files = new ArrayList

You should put in

Option Explicit 'On
Option Strict On

at the top of your code. you'll help yourself out a little bit by now
declaring objects correctly in vb.net

THanks, sloan. Yes, I NEED to get in the habit of using the option
explicit/strict feature.
