i'm somewhat new to vb, but i am writing this code using vb.net and in the process of learning stumbled across an arraylist

i tried converting the arraylist to an array using

dim a as array
a = mailbody.toarray()

and then attempted to print out the array on a email

message.body = string.join(vbnewline, a)

somehow this code isn't working and i can't figure out how, any help would be gladly appreciated ^^
