Je suis tout nouveau dans le ASP.NET Domaine C#. J'ai l'intention d'envoyer un courrier via ASP.NET C# et c'est l'objet de l'enquête. SMTP adresse de mon ISP :

smtp-proxy.tm.net.my

Voici ce que j'ai essayé de faire, mais sans succès.

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="SendMail" %>
<html>
<head id="Head1" runat="server"><title>Email Test Page</title></head>
<body>
    <form id="form1" runat="server">
        Message to: <asp:TextBox ID="txtTo" runat="server" /><br>
        Message from: <asp:TextBox ID="txtFrom" runat="server" /><br>
        Subject: <asp:TextBox ID="txtSubject" runat="server" /><br>
        Message Body:<br>
        <asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine"  Width="270px" /><br>
        <asp:Button ID="Btn_SendMail" runat="server" onclick="Btn_SendMail_Click" Text="Send Email" /><br>
        <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
    </form>
</body>
</html>

Et ci-dessous, mon code-behind :

using System;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class SendMail : System.Web.UI.Page
{
    protected void Btn_SendMail_Click(object sender, EventArgs e)
    {
        MailMessage mailObj = new MailMessage(
            txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
        SmtpClient SMTPServer = new SmtpClient("127.0.0.1");
        try
        {
            SMTPServer.Send(mailObj);
        }
        catch (Exception ex)
        {
            Label1.Text = ex.ToString();
        }
    }
}

PS : Je suis désolé de ne pas avoir pu comprendre le concept SMTP récepteur/émetteur, et j'essaie donc de comprendre l'ensemble du concept à partir d'ici.

Il suffit de passer par le code ci-dessous.

SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);

smtpClient.Credentials = new System.Net.NetworkCredential("info@MyWebsiteDomainName.com", "myIDPassword");
// smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();

//Setting From , To and CC
mail.From = new MailAddress("info@MyWebsiteDomainName", "MyWeb Site");
mail.To.Add(new MailAddress("info@MyWebsiteDomainName"));
mail.CC.Add(new MailAddress("MyEmailID@gmail.com"));

smtpClient.Send(mail);

Essayez d'utiliser ce code à la place. Note : Dans le champ "adresse de départ", indiquez votre adresse e-mail et votre mot de passe.

protected void btn_send_Click(object sender, EventArgs e)
{

    System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
    mail.To.Add("to gmail address");
    mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8);
    mail.Subject = "This mail is send from asp.net application";
    mail.SubjectEncoding = System.Text.Encoding.UTF8;
    mail.Body = "This is Email Body Text";
    mail.BodyEncoding = System.Text.Encoding.UTF8;
    mail.IsBodyHtml = true;
    mail.Priority = MailPriority.High;
    SmtpClient client = new SmtpClient();
    client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password");
    client.Port = 587;
    client.Host = "smtp.gmail.com";
    client.EnableSsl = true;
    try
    {
        client.Send(mail);
        Page.RegisterStartupScript("UserMsg", "<script>alert('Successfully Send...');if(alert){ window.location='SendMail.aspx';}</script>");
    }
    catch (Exception ex)
    {
        Exception ex2 = ex;
        string errorMessage = string.Empty;
        while (ex2 != null)
        {
            errorMessage += ex2.ToString();
            ex2 = ex2.InnerException;
        }
        Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>");
    }
}

Vous pouvez essayer en utilisant hotmail comme ceci :-.

MailMessage o = new MailMessage("From", "To","Subject", "Body");
NetworkCredential netCred= new NetworkCredential("Sender Email","Sender Password");
SmtpClient smtpobj= new SmtpClient("smtp.live.com", 587); 
smtpobj.EnableSsl = true;
smtpobj.Credentials = netCred;
smtpobj.Send(o);

Essayez ce qui suit :

try
{
    var fromEmailAddress =  ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
    var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
    var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
    var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
    var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();

    string body = "Your registration has been done successfully. Thank you.";
    MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
    message.Subject = "Thank You For Your Registration";
    message.IsBodyHtml = true;
    message.Body = body;

    var client = new SmtpClient();
    client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
    client.Host = smtpHost;
    client.EnableSsl = true;
    client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
    client.Send(message);
}
catch (Exception ex)
{
    throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}

Puis, dans votre web.config, ajoutez les éléments suivants entre les deux

<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>

Vous pouvez essayer MailKit MailKit est une bibliothèque de client de messagerie Open Source multiplateforme .NET basée sur MimeKit et optimisée pour les appareils mobiles. Vous pouvez l'utiliser facilement dans votre application. aquí .

                MimeMessage mailMessage = new MimeMessage();
                mailMessage.From.Add(new MailboxAddress(fromName, from@address.com));
                mailMessage.Sender = new MailboxAddress(senderName, sender@address.com);
                mailMessage.To.Add(new MailboxAddress(emailid, emailid));
                mailMessage.Subject = subject;
                mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
                mailMessage.Subject = subject;
                var builder = new BodyBuilder();
                builder.TextBody = "Hello There";           
                try
                {
                    using (var smtpClient = new SmtpClient())
                    {
                        smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
                        smtpClient.Authenticate("user@name.com", "password");

                        smtpClient.Send(mailMessage);
                        Console.WriteLine("Success");
                    }
                }
                catch (SmtpCommandException ex)
                {
                    Console.WriteLine(ex.ToString());              
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.ToString());                
                }
