how to replace the last comma in a comma separated list with ' and '

Hi

I am using vb.net 2005 and I'm not very familiar with regular expressions.

If i had a comma separated list of items in a string, how would i locate the last comma in the list and replace it with ' and '

for example

me, you becomes me and you
me, you, barbara becomes me, you and barbara

thanks a lot

        Dim str As String = "me, you, barbara"
        Dim index as integer = str.LastIndexOf(","c)
        str = str.Substring(0, index) & " and" & str.Substring(index + 1)
