Craig,

You can parse the values, however you will need to manually build the array.

You can use the following RegEx to parse the string:
Dim ex As New Regex("^\""(?<name>.*)\"" \<(?<address>.*)\>$")
Dim match As Match = ex.Match("""Herman Munster"" <1313 Mocking Bird
Lane>")
Debug.WriteLine(match.Groups("name"), "name")
Debug.WriteLine(match.Groups("address"), "address")

You will not have a match, so yes you will have an empty string returned.

Nothing, they are both an array of Strings, the first is useful when you are
defining a string scalar & array on the same line, while the second is
needed for function & property return values.
Dim y, x() as String
Public Function ReturnStringArray() As String()
Hope this helps
