Have you tried something yourself to validate the email? like regularexpressions? — Murtaza Zaidi, Oct 05 '14 at 10:19
use regular expressions or a loop that checks all the characters. — Gmnd-i, Oct 05 '14 at 11:11

Try this method.

public bool IsValid(string emailaddress)
{
    try
    {
        MailAddress m = new MailAddress(emailaddress);

        return true;
    }
    catch (FormatException)
    {
        return false;
    }
}

If you check this link: http://stackoverflow.com/questions/5342375/c-sharp-regex-email-validation you'll that this is not a good way. – Oct 05 '14 at 10:15
didn't work 'IsValid' – Kusal Arunoda Oct 07 '14 at 04:58
@Hypenate To be fair, that's probably where they copied the answer from in the first place, not bothering to read why it's horribly wrong. ;) – J. Steen Feb 02 '15 at 08:12
