Hi

I need to send email with a list. When I insert the email list, I need to validate the format of it in C# code.

while (!str.EndOfStream)
                {
                        string email = str.ReadLine().Split(new char[] { ' ,' });
                        //add to email program
}

How can I validate email address with proper format?

Thanks
