Question

i am not very experienced in Regular Expression so its why i am asking you 🙂
my question is i use this pattern when i validate Emails.

/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zAZ\-0-9]+\.)+[a-zA-Z]{2,}))$/

what is it to add to this pattern to disallow Arabic characters ?

Answer 1

Regular expressions should not be used to validate emails.

The correct way to validate an email address is using the MailAddress class like this:

try 
{
    string address = new MailAddress(address).Address;
} 
catch(FormatException) 
{
    //address is invalid
}

---

Regarding the question itself, after you see that it is a valid email address – you can check for arabic characters.
