<p>I'm storing an ArrayList of Ids in a processing script that I want to spit out as a comma delimited list for output to the debug log. Is there a way I can get this easily without looping through things?</p>

<p>EDIT: Thanks to Joel for pointing out the List(Of T) that is available in .net 2.0 and above. That makes things TONS easier if you have it available.</p>

Yes, I'm answering my own question, but I haven't found it here yet and thought this was a rather slick thing:
...in VB.NET:
```
```
String.Join(",", CType(TargetArrayList.ToArray(Type.GetType("System.String")), String()))
```
```
...in C#
```
```
string.Join(",", (string[])TargetArrayList.ToArray(Type.GetType("System.String")))
```
```
The only "gotcha" to these is that the ArrayList must have the items stored as Strings if you're using Option Strict to make sure the conversion takes place properly.
EDIT: If you're using .net 2.0 or above, simply create a List(Of String) type object and you can get what you need with. Many thanks to Joel for bringing this up!
```
```
String.Join(",", TargetList.ToArray())
```
