Subject: array to string conversion

Hi, I have 2 arrays(which is part of the hash):

ex = {}
ex[0] = ["xls", "ini", "20080326"]
ex[1] = ["gif", "xls", "rb"]

All i managed to convert is(using .to_s):
str[0] = "xlsini20080326"
str[1] = "gifxlsrb"

but i want to convert each array into a string, something like
str[0] = "xls,ini,20080326"
str[1] = "gif,xls,rb"

where they are seperated by a comma.. Any clean way of doin this?
