I want to send a single mail to number of users. I have extracted the email addresses of all those in datatable, now I am wondering how can I pass this datatable to BCC or CC in mail.
You achieve it by doing something like this
MailMessage MyMail = new MailMessage();
MyMail.From = "some email address";
foreach(DataRow row in dataTable1.Rows)
{
MyMail.To += row["email"] + ";"
}
