removing alpha characters from string

Brian Henry

Is there any quick and easy (other then scanning a string char by char) to
remove all the alpha chars from a string and leave only numbers?

ex:

A12334234-3431AP

comes out to 123342343431
thanks!

Dim s As String = "A23zb4-u98"
MsgBox(Regex.Replace(s, "[^0-9]", ""))

just use a regex that extracts only the numbers?
