Comment envoyer un courrier électronique à plusieurs adresses à l'aide de System.Net.Mail
J'ai la fonctionnalité de messagerie smtp. cela fonctionne pour une adresse unique mais a un problème dans plusieurs adresses.
je passe plusieurs adresses en utilisant la ligne de code suivante.
MailAddress to = new MailAddress("[email protected],[email protected]");
S'il vous plaît laissez-moi savoir le problème car je ne reçois aucune erreur.
MailMessage msg = new MailMessage();
msg.Body = ....;
msg.To.Add(...);
msg.To.Add(...);
SmtpClient smtp = new SmtpClient();
smtp.Send(msg);
To est une MailAddressCollection, vous pouvez donc ajouter le 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));
essaye ça..
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 adresses sortantes ayant un nom d'affichage (également différent):
//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);
}
La suggestion de StewieFG est valide, mais si vous souhaitez ajouter le nom du destinataire, utilisez ceci, avec ce que Marco a publié ci-dessus, mais il s'agit d'abord d'une adresse électronique et du nom complet ensuite:
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);
}
}
