通过Gmail发送电子邮件 [英] Sending Email through Gmail

问题描述

我正在写一个通过GMail发送电子邮件的程序，但是我有严重的操作超时错误。什么是可能的原因。

  class Mailer 
 {
 
 MailMessage ms; 
 SmtpClient Sc; 
 public Mailer（）
 {
 Sc = new SmtpClient（smtp.gmail.com）; 
 
 //Sc.Credentials = CredentialCache.DefaultNetworkCredentials; 
 Sc.EnableSsl = true; 
 Sc.Port = 465; 
 Sc.Timeout = 900000000; 
 Sc.DeliveryMethod = SmtpDeliveryMethod.Network; 
 Sc.UseDefaultCredentials = false; 
 Sc.Credentials = new NetworkCredential（uid，mypss）; 
 
 
} 
 public void MailTodaysBirthdays（List< Celebrant> TodaysCelebrant）
 {
 int i = TodaysCelebrant.Count（）; 
 foreach（Celebrant cs in TodaysCelebrant）
 {
 // if（IsEmail（cs.EmailAddress.ToString（）。Trim（）））
 // {
 ms = new MailMessage（）; 
 ms.To.Add（cs.EmailAddress）; 
 ms.From = new MailAddress（uid，Developers，System.Text.Encoding.UTF8）; 
 ms.Subject =生日快乐; 
 
 String EmailBody =生日快乐+ cs.FirstName; 
 ms.Body = EmailBody; 
 ms.Priority = MailPriority.High; 
 
 try 
 {
 Sc.Send（ms）; 
} 
 catch（Exception ex）
 {
 Sc.Send（ms）; 
 BirthdayServices.LogEvent（ex.Message.ToString（），EventLogEntryType.Error）; 
} 
 //} 
 
 
} 
 
} 
 
 
} 
  

解决方案

您只需要将端口更改为587

I am writing a program that send an email through GMail but I have serious Operation timeout error. What is the likely cause.

class Mailer
{

    MailMessage ms;
    SmtpClient Sc;
    public Mailer()
    {
        Sc = new SmtpClient("smtp.gmail.com");

        //Sc.Credentials = CredentialCache.DefaultNetworkCredentials;
        Sc.EnableSsl = true;
        Sc.Port =465;
        Sc.Timeout = 900000000;
        Sc.DeliveryMethod = SmtpDeliveryMethod.Network;
        Sc.UseDefaultCredentials = false;
        Sc.Credentials = new NetworkCredential("uid", "mypss");


    }
    public void MailTodaysBirthdays(List<Celebrant> TodaysCelebrant)
    {
        int i = TodaysCelebrant.Count();
        foreach (Celebrant cs in TodaysCelebrant)
        {
            //if (IsEmail(cs.EmailAddress.ToString().Trim()))
            //{
           ms = new MailMessage();
           ms.To.Add(cs.EmailAddress);
           ms.From = new MailAddress("uid","Developers",System.Text.Encoding.UTF8);
           ms.Subject = "Happy Birthday ";

           String EmailBody = "Happy Birthday " + cs.FirstName;
           ms.Body = EmailBody;
           ms.Priority = MailPriority.High;

           try
            {
              Sc.Send(ms);
            }
                catch (Exception ex)
                {
                    Sc.Send(ms);
                    BirthdayServices.LogEvent(ex.Message.ToString(),EventLogEntryType.Error);
                }
            //}


        }

    }


    }

解决方案
