How do I add another email address in my C#?

Question

I would like to add an extra email address for messages to be sent/forwarded to when the email form submit button is clicked, whats the easiest way to do this?

public partial class Contact : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
    string name = txtName.Text;
    string emailaddress = txtEmail.Text;
    string body = txtComment.Text;


    MailAddress From = new MailAddress(emailaddress);
    MailAddress To = new MailAddress("111@1111.com");
    MailMessage email = new MailMessage(From, To);
    email.Subject = "Comment from Website from " + name;
    email.Body = body;

    SmtpClient smtp = new SmtpClient("smtp.1111.com");
    smtp.Credentials = new System.Net.NetworkCredential("111@1111.com", "1111111111");
    smtp.Send(email);
    email.Dispose();

    ClientScript.RegisterClientScriptBlock(this.GetType(), "Email Confirm", "alert('Email Sent!');", true);

    txtComment.Text = "";
    txtEmail.Text = "";
    txtName.Text = "";


}
protected void txtEmail_TextChanged(object sender, EventArgs e)
{

}
}

We'll say that my extra email address is smtp.2222.com 222@2222.com with an authentication of 22222. Thanks for looking folks.

Answer 1

Instead of using the To.Add method, you can pass a comma separated list of email address to MailMessage constructor which is a much better solution especially if you have more than a few email addresses to send the email to...

var from = "me@me.com";
var to = "mail1@domain.com,mail2@domain.com,mail3@domain.com";
var subject = "My Subject";
var body = "Message Body";
var message = new MailMessage(from, to, subject, body);

will work just as well...

Answer 2

Simple:

…
MailAddress From = new MailAddress(emailaddress);
MailMessage email = new MailMessage(from, to);
email.To.Add(new MailAddress("111@1111.com"));
email.To.Add(new MailAddress("222@2222.com"));
email.Subject = "Comment from Website from " + name;
email.Body = body;
