Thank you for the reply.
Actually I resolved my issue as follows:
Replace the following:
Dim Address() As String = Request.Form("Addresses").Split(",")
By:
Dim Addresses As String() = Request.Form.GetValues("Addresses")
Now the two strings containing commas are separated as follows:
Address(0) - "01 My Street, My Town, My City, My PostCode"
Address(1) - "02 My Street, My Town, My City My, PostCode"
