Envoyer un courrier électronique via SMTP en utilisant C #
Je ne comprends pas pourquoi ce code ne fonctionne pas. Je reçois une erreur disant que la propriété ne peut pas être attribuée
MailMessage mail = new MailMessage();
SmtpClient client = new SmtpClient();
client.Port = 25;

mail.To = "[email protected]"; // <-- this one
mail.From = "[email protected]";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
mail.To et mail.From sont en lecture seule. Déplacez-les vers le constructeur.

C'est comme ça que ça marche pour moi. J'espère que vous le trouverez utile

Commencez par accéder à https://myaccount.google.com/lesssecureapps et rendre Autoriser les applications moins sécurisées true.
Ensuite, utilisez le code ci-dessous. Le code ci-dessous ne fonctionnera que si votre adresse e-mail de provient de gmail.
static void SendEmail()
{
string mailBodyhtml =
"<p>some text here</p>";
var msg = new MailMessage("[email protected]", "[email protected]", "Hello", mailBodyhtml);
msg.To.Add("[email protected]");
msg.IsBodyHtml = true;
var smtpClient = new SmtpClient("smtp.gmail.com", 587); **//if your from email address is "[email protected]" then Host should be "smtp.hotmail.com"**
smtpClient.UseDefaultCredentials = true;
smtpClient.Credentials = new NetworkCredential("[email protected]", "password");
smtpClient.EnableSsl = true;
smtpClient.Send(msg);
Console.WriteLine("Email Sended Successfully");
}
Si vous souhaitez que votre adresse électronique et votre mot de passe n'apparaissent pas dans votre code, vous souhaitez que le serveur client de messagerie de votre société utilise vos informations d'identification Windows, comme indiqué ci-dessous.
client.Credentials = CredentialCache.DefaultNetworkCredentials;
Cela a juste fonctionné pour moi à partir de mars 2017 . Commencé avec la solution ci-dessus "Finalement got work :)" qui n'a pas fonctionné au début.

mm.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
client.Send(mm);
MailMessage mm = new MailMessage(txtEmail.Text, txtTo.Text);
mm.Subject = txtSubject.Text;
mm.Body = txtBody.Text;
if (fuAttachment.HasFile)//file upload select or not
{
string FileName = Path.GetFileName(fuAttachment.PostedFile.FileName);
mm.Attachments.Add(new Attachment(fuAttachment.PostedFile.InputStream, FileName));
}
mm.IsBodyHtml = false;
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.EnableSsl = true;
NetworkCredential NetworkCred = new NetworkCredential(txtEmail.Text, txtPassword.Text);
smtp.UseDefaultCredentials = true;
smtp.Credentials = NetworkCred;
smtp.Port = 587;
smtp.Send(mm);
Response.write("Send Mail");
Voir la vidéo:https://www.youtube.com/watch?v=bUUNv-19QAI

Cette réponse comporte:
- Utiliser 'using' autant que possible ( IDisposable interfaces)
- Utilisation de Initialiseurs d’objets
- Programmation Async
- Extrayez SmtpConfig dans une classe externe (ajustez-le à vos besoins)
Voici le code extrait:
public async Task SendAsync(string subject, string body, string to)
{
using (var message = new MailMessage(smtpConfig.FromAddress, to)
{
Subject = subject,
Body = body,
IsBodyHtml = true
})
{
using (var client = new SmtpClient()
{
Port = smtpConfig.Port,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Host = smtpConfig.Host,
Credentials = new NetworkCredential(smtpConfig.User, smtpConfig.Password),
})
{
await client.SendMailAsync(message);
}
}
}
Classe SmtpConfig:
public class SmtpConfig
{
public string Host { get; set; }
public string User { get; set; }
public string Password { get; set; }
public int Port { get; set; }
public string FromAddress { get; set; }
}
Initialisez la MailMessage avec les adresses électroniques de l'expéditeur et du destinataire. Cela devrait être quelque chose comme
string from = "[email protected]"; //Senders email
string to = "[email protected]"; //Receiver's email
MailMessage msg = new MailMessage(from, to);
