Hi

I need to match strings to this format

1/5,
2/5
3/5
4/5
5/5


e.g. [1..5]/5

what's the easiest way to make sure an input string matches one of these values and then extract the number before the slash?

thanks
andrea

Hi andrea, this should do what your after:

Imports System.Text.RegularExpressions
...

Dim Data As String = "1/5"
Dim Match As String = Regex.Match(Data, "(?<value>[1-5])/5").Groups("value").Value

If (Match <> String.Empty) Then
      'use Match string here (in this case it holds the string "1")
End If
