Sending mail from ASP.NET application

Question

Is there a way to send mail from an asp.net application? Right now I'm trying to figure out how to create confirmation emails when you sign up for a service.

Answer 1

System.Web.Mail.MailMessage message=new System.Web.Mail.MailMessage();
message.From="from e-mail";
message.To="to e-mail";
message.Subject="Message Subject";
message.Body="Message Body";
System.Web.Mail.SmtpMail.SmtpServer="SMTP Server Address";
System.Web.Mail.SmtpMail.Send(message);

Answer 2

Check out the SmtpClient class . For example code, see this answer from Shlomi.

Answer 4

this code will get you started using (MailMessage mm = new MailMessage()) {

                mm.From = new MailAddress("noreply@mail.com");

                SmtpClient client = new SmtpClient("127.0.0.1");

                string smtpServerUserName = "username";
                string smtpServerPassword = "password"; 
            if (smtpServerUserName.HasValue() && smtpServerPassword.HasValue())
                {
                    client.Credentials = new NetworkCredential(smtpServerUserName, smtpServerPassword);
                }
                smtpServerPort = "";
                if (smtpServerPort.HasValue())
                {
                    client.Port = Convert.ToInt32(smtpServerPort, CultureInfo.InvariantCulture);
                }
                mm.Priority = MailPriority.Normal;

                mm.IsBodyHtml = false;

                mm.Subject = subject;
                mm.To.Add(new MailAddress("you@home.com"));
                mm.Body = body;

                client.Send(mm);
            }
        }

where hasvalue() is just a extensionmethod which inverts string.IsNullOrEmpty()

you can use papercut (http://papercut.codeplex.com/) to test it on your local pc, then use 127.0.0.1 as ipaddress without any smtpusername, password or portnumber.

/// <summary>
    /// checks if a string is null or empty (hasvalue = false if null or empty)
    /// </summary>
    /// <param name="s"></param>
    /// <returns></returns>
    public static bool HasValue(this string s)
    {
        if (string.IsNullOrEmpty(s))
        {
            return false;
        }
        return true;
    }
