Cómo enviar un correo electrónico a varias direcciones usando System.Net.Mail

Question

Tengo la funcionalidad de correo electrónico smtp. funciona para una sola dirección pero tiene un problema en varias direcciones.

Estoy pasando varias direcciones utilizando la siguiente línea de código.

MailAddress to = new MailAddress("[email protected],[email protected]");

Por favor, hágame saber el problema ya que no estoy recibiendo ningún error.

Answer 1

Creo que puede usar este código para tener una lista de direcciones salientes con un nombre de visualización (también diferente):

//1.The ACCOUNT
MailAddress fromAddress = new MailAddress("[email protected]", "my display name");
String fromPassword = "password";

//2.The Destination email Addresses
MailAddressCollection TO_addressList = new MailAddressCollection();

//3.Prepare the Destination email Addresses list
foreach (var curr_address in mailto.Split(new [] {";"}, StringSplitOptions.RemoveEmptyEntries))
{
    MailAddress mytoAddress = new MailAddress(curr_address, "Custom display name");
    TO_addressList.Add(mytoAddress);
}

//4.The Email Body Message
String body = bodymsg;

//5.Prepare GMAIL SMTP: with SSL on port 587
var smtp = new SmtpClient
{
    Host = "smtp.gmail.com",
    Port = 587,
    EnableSsl = true,
    DeliveryMethod = SmtpDeliveryMethod.Network,
    Credentials = new NetworkCredential(fromAddress.Address, fromPassword),
    Timeout = 30000
};


//6.Complete the message and SEND the email:
using (var message = new MailMessage()
        {
            From = fromAddress,
            Subject = subject,
            Body = body,
        })
{
    message.To.Add(TO_addressList.ToString());
    smtp.Send(message);
}

Answer 2

Estoy acostumbrado "para" operador.

try
{
    string s = textBox2.Text;
    string[] f = s.Split('','');

    for (int i = 0; i < f.Length; i++)
    {
        MailMessage message = new MailMessage(); // Create instance of message
        message.To.Add(f[i]); // Add receiver
        message.From = new System.Net.Mail.MailAddress(c);// Set sender .In this case the same as the username
        message.Subject = label3.Text; // Set subject
        message.Body = richTextBox1.Text; // Set body of message
        client.Send(message); // Send the message
        message = null; // Clean up
    }

}

catch (Exception ex)
{

    MessageBox.Show(ex.Message);
}

Answer 3

La sugerencia de StewieFG es válida, pero si desea agregar el nombre del destinatario, use esto, con lo que Marco ha publicado anteriormente, pero primero es la dirección de correo electrónico y luego el nombre para mostrar

msg.To.Add(new MailAddress("[email protected]","Your name 1"));
msg.To.Add(new MailAddress("[email protected]","Your name 2"));

Answer 4

Mi código para resolver este problema:

private void sendMail()
{   
    //This list can be a parameter of metothd
    List<MailAddress> lst = new List<MailAddress>();

    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));
    lst.Add(new MailAddress("[email protected]"));


    try
    {


        MailMessage objeto_mail = new MailMessage();
        SmtpClient client = new SmtpClient();
        client.Port = 25;
        client.Host = "10.15.130.28"; //or SMTP name
        client.Timeout = 10000;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential("[email protected]", "password");
        objeto_mail.From = new MailAddress("[email protected]");

        //add each email adress
        foreach (MailAddress m in lst)
        {
            objeto_mail.To.Add(m);
        }


        objeto_mail.Subject = "Sending mail test";
        objeto_mail.Body = "Functional test for automatic mail :-)";
        client.Send(objeto_mail);


    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

Answer 5

prueba esto..

using System;
using System.Net.Mail;

public class Test
{
    public static void Main()
    {
        SmtpClient client = new SmtpClient("smtphost", 25);
        MailMessage msg = new MailMessage("[email protected]", "[email protected],[email protected]");
        msg.Subject = "sdfdsf";
        msg.Body = "sdfsdfdsfd";
        client.UseDefaultCredentials = true;
        client.Send(msg);
    }
}

 {
    message.To.Add(new MailAddress(ToEmail)); //adding multiple email addresses
 }

Answer 8

MailAddress fromAddress = new MailAddress  (fromMail,fromName);
MailAddress toAddress = new MailAddress(toMail,toName);
MailMessage message = new MailMessage(fromAddress,toAddress);
message.Subject = subject;
message.Body = body;
SmtpClient smtp = new SmtpClient()
{
    Host = host, Port = port,
    enabHost = "smtp.gmail.com",
    Port = 25,
    EnableSsl = true,
    UseDefaultCredentials = true,
    Credentials = new  NetworkCredentials (fromMail, password)
};
smtp.send(message);

Answer 9

MailMessage msg = new MailMessage();
msg.Body = ....;
msg.To.Add(...);
msg.To.Add(...);

SmtpClient smtp = new SmtpClient();
smtp.Send(msg);

To es un MailAddressCollection , por lo que puede agregar cuántas direcciones necesita.

Si necesita un nombre para mostrar, intente esto:

MailAddress to = new MailAddress(
    String.Format("{0} <{1}>",display_name, address));
