Solution 1

since + is a special character , you need to escape plus sign in your regex

something like this

@"^([\w-\.\+]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"

Hi NAZ_Firdouse , is there any option to allow only for email end with valid domain name like .com,in etc..

Naz_Firdouse 8-Apr-14 6:18am

In that case , you need to manually specify the domain names you need
