Expressions1. Confirm the valid email formatThe following code example uses the static Regex. IsMatch method to verify whether a string is in a valid email format. If the string contains a valid email address, the IsValidEmail method returns true; otherwise, the return value is false without any other operations. You can use IsValidEmail to filter out email addresses that contain invalid characters before the application stores the addresses in the database or displays them on the ASP. NET page
