Hi KRayudu, Regular expression are powerful tools to check whether string match the case or not. I had found a good article on Regular Expression for Email address checking. Having sample code here. public static class TestEmail { /// /// Regular expression, which is used to validate an E-Mail address. /// public const string MatchEmailPattern = @"^(([\w-]+\.)+[\w-]+|([a-zA-Z]{1}|[\w-]{2,}))@" + @"((([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\.([0-1]? [0-9]{1,2}|25[0-5]|2[0-4][0-9])\." + @"([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\.([0-1]? [0-9]{1,2}|25[0-5]|2[0-4][0-9])){1}|" + @"([a-zA-Z]+[\w-]+\.)+[a-zA-Z]{2,4})$"; /// /// Checks whether the given Email-Parameter is a valid E-Mail address. /// /// Parameter-string that contains an E-Mail address. /// True, when Parameter-string is not null and /// contains a valid E-Mail address; /// otherwise false. public static bool IsEmail(string email) { if (email != null) return Regex.IsMatch(email, MatchEmailPattern); else return false; } } Link to this article is " Email Validation using Regular Expression " Thanks & Regards ---------------------- Chintan Rathod
