The MailAddress class is used for creating email addresses. This class is used for setting the MailMessage.From, MailMessage.To, MailMessage.CC and MailMessage.BCC properties. Of these properties the .From class is actually a MailAddress, while the To, CC and BCC properties are actually collections of MailAddresses. The two most common properties of the MailAddress class are the DisplayName and the Address properties. They are described below.

Below is an example demonstrating the MailAddress class.

[ C# ]

 static void MultipleRecipients()
{
//create the mail message
MailMessage mail = new MailMessage();

//set the addresses
//to specify a friendly 'from' name, we use a different ctor
mail.From = new MailAddress("me@mycompany.com", "Steve James");

//since the To,Cc, and Bcc accept addresses, we can use the same technique as the From address
//since the To, Cc, and Bcc properties are collections, to add multiple addreses, we simply call .Add(...) multple times
mail.To.Add("you@yourcompany.com");
mail.To.Add("you2@yourcompany.com");
mail.CC.Add("cc1@yourcompany.com");
mail.CC.Add("cc2@yourcompany.com");
mail.Bcc.Add("blindcc1@yourcompany.com");
mail.Bcc.Add("blindcc2@yourcompany.com");

//set the content
mail.Subject = "This is an email";
mail.Body = "this is the body content of the email.";

//send the message
SmtpClient smtp = new SmtpClient("127.0.0.1");
smtp.Send(mail);
}
