Regular expressions

Hi
I need a regex to validate a string that must ends with "/" and 2 digits

Examples

"aaa/" not ok
"aaa/0a" not ok
"bdc/88" ok

Thanks
Jorge

VB Code:

Dim tbox As TextBox = DirectCast(sender, TextBox)
        If Regex.IsMatch(tbox.Text, "^([a-zA-Z]+)/([0-9]{2,2})$") = True Then
        Else
            MsgBox("Not valid String")
        End If

i assumed that the first part of the string contains only char not num

Modified it slightly its working now

VB Code:

Dim tbox As TextBox = DirectCast(sender, TextBox)
        If Regex.IsMatch(tbox.Text, "^([a-zA-Z0-9.]+)/([0-9]{2,2})$") = True Then
        Else
            MsgBox("Not valid String")
        End If

Thanks
Jorge
