Joining it all together into a long string with a delimiter is probably the easiest way to go. The other way is to convert to XML.
If I recall correctly, VB has a function called Join which does what you want and a function called Split to convert back to an array. I don't recall if those are available in the VBScript you get with ASP. They probably are. I assume you're using "classic asp", not asp.net.
