Regex Question

[mavrick_101]

Hi,

I'm trying to validate user input for a text field.

I do not want them to enter special characters like <, > ! @ etc.

How can I do that using Regex.

Thnx for your help.

Use this

^\w*$

This would allow only 0..9 and a..zA..Z (\*)

^ means beginning of the word, $ - end

if (Regex.IsMatch(str, @"^\w*$"))
return "Error";
