public static class EmailValidator {
    static Regex ValidEmailRegex = new Regex(
            + @"([-a-z0-9!#$%&'*+/=?^_`{|}~]|(?<!\.)\.)*)(?<!\.)"
            + @"@[a-z0-9][\w\.-]*[a-z0-9]\.[a-z][a-z\.]*[a-z]$"
            , RegexOptions.IgnoreCase);
    public static bool IsValid(string emailAddress) {
        return ValidEmailRegex.IsMatch(emailAddress);
