Send Email to multiple Recipients with MailMessage?

Easy!

Just split the incoming address list on the “;” character, and add them to the mail message:

foreach (var address in addresses.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
    mailMessage.To.Add(address);    
}

In this example, addresses contains “address1@example.com;address2@example.com“.
