Regular Expression Error

I'm trying to use regular expressions in my ASP.NET doc, and I'm running into a problem. This is how I've set it up:

Code:

<%@ import Namespace="System.Text.RegularExpressions" %>
<%
'Validate form data - required fields only
Dim RegularExpressionObject As Object

RegularExpressionObject = New RegExp

    With RegularExpressionObject
    .Pattern = "[A-Za-z0-9]"
    .IgnoreCase = True
    .Global = True
End With
%>

And this is the error that I'm receiving:
Compilation Error
Type 'RegExp' is not defined.

Line 77: Dim RegularExpressionObject As Object
Line 78:
Line 79: RegularExpressionObject = New RegExp
Line 80:
Line 81: With RegularExpressionObject

If anyone can give me some advice on my I'm getting this error message, it would be greatly appreciated. Thanks.

Hey,

ASP.NET? That is the ASP approach, in ASP.NET, you put your code in the <script runat="server"></script> tags. You have the right namespace, but I believe it is Regex now. Match still exists.

I'm actually using XML & XSL transformed using ASP.NET, and then I use background ASP.NET/VB scripts wherever needed. This specific script performs server-side tasks...not client-side for the form.

I've already set up the rest of this form with no problems using this setup. The only problem I'm having is with Regular Expressions. If I'm declaring the Regular Expression's namespace at the very beginning of the ASP.NET doc, and then trying to call the "New RegExp" method, why would I then receive this error message? Thanks for any help.

Well, I looked further into 4guysfromrolla's articles on ASP.NET Regular Expressions, and I found a good one at http://aspnet.4guysfromrolla.com/articles/022603-1.aspx. It had a method that works like this:

Dim test_value As String = "+" '(plus sign)
If Regex.IsMatch(fname_form, "^+") Then
Response.Write(errormessage)
End If
...and it works. I now just have to work with what characters I will allow for each field.

Thanks again for your help. I really appreciate it.
