Validatiom email

What are you hoping to validate, an email *address*, or something else ? Regex to validate email addresses are pretty common, I think expresso even has one built in.

This is the regex for email addresses in expresso:

([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})

So something like

if (Regex.IsMatch(string, @"([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})"))

will return true if string is an email address

Don't forget to put using System.Text.RegularExpressions;
