Comment envoyer des e-mail à plusieurs adresses en utilisant le Système.Net.Mail

J'ai une fonctionnalité de messagerie smtp. il fonctionne pour une seule adresse, mais a un problème dans de multiples adresses.

je suis passé plusieurs adresses à l'aide de ligne de code suivante.

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

S'il vous plaît laissez-moi savoir le problème que je n'obtiens pas d'erreur.

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

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

    To est un MailAddressCollection, de sorte que vous pouvez ajouter du nombre d'adresses dont vous avez besoin.

    Si vous avez besoin d'un nom d'affichage, essayez ceci:

    MailAddress to = new MailAddress(
    String.Format("{0} <{1}>",display_name, address));
    • Ce sujet à partir de l'adresse?
    • utilisation msg.From bien... quel est le problème avec ça? 😉
    • en fait, j'ai virgule liste avec des adresses avec moi. donc, une autre réponse à cette question est convenable mais que je n'ai pas trouver de toute façon d'attribuer le nom d'affichage de l'adresse de l'expéditeur.
    • Vous n'avez pas besoin d'ajouter chaque destinataire séparément. msg.To.Add("[email protected],[email protected]"); fonctionne très bien.
    • Quiconque connaît les limites du nombre d'adresses peut To et CC inclure? Je ne trouve aucune info sur MSDN...

    essayer cette..

    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);
    }
}

    Je pense que vous pouvez utiliser ce code pour avoir la Liste des sortants des Adresses d'avoir un Nom d'affichage (également différente):

    //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);
}

    StewieFG suggestion est valide, mais si vous voulez ajouter le nom du destinataire utilisez cette, avec ce que Marco a posté ci-dessus, mais est l'adresse email de la première et le nom d'affichage deuxième:

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

    Mon code pour résoudre ce problème:

    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);
    }
}
    • Assurez-vous de disposer de la objecto_mail après envoyer. Ou utiliser un bloc using.

    • veuillez formater votre code mieux, et d'essayer de le compiler avant de poster. cette new SmtpClient() {enabHost = "smtp.gmail.com",} ne compilera pas. Poster un code qui compile.
