Flex: Convert ArrayCollection to jagged String Array

Is there any built in functionality to convert an ArrayCollection to a jagged string array? I have an Arraycollection of objectproxies that I get from a SO开发者_运维百科AP webservice (asp.net datatable) that I modify and want to send back.

Thanks, Brian

I just ended up writing something myself to do it. I was just hoping that there was another way.
