使用SmtpClient从Gmail发送电子邮件 [英] Using SmtpClient to send an email from Gmail

问题描述

我试图连接到我的Gmail帐户通过 SmtpClient ，但它似乎不是应该工作。我指定端口465，启用SSL和定义的一切，但它需要像2分钟，然后只是显示一些错误未发送邮件。

我在做什么？错在这里。

 试
 {
味精MAILMESSAGE新= MAILMESSAGE（）; 
 msg.From =新的MailAddress（[e-mail]）; 
 msg.To.Add（新MailAddress（[e-mail]））; 
 msg.Subject =这是主题; 
 msg.Body =这是身体; 
 SmtpClient SC =新SmtpClient（smtp.gmail.com，465）; 
 sc.EnableSsl = TRUE; 
 sc.UseDefaultCredentials = FALSE; 
 sc.Credentials =新的NetworkCredential（[e-mail]，传）; 
 sc.DeliveryMethod = SmtpDeliveryMethod.Network; 
 sc.Send（MSG）; 
 erroremail.Text =电子邮件已成功发送。 
} 
赶上（异常前）
 {
 erroremail.Text =错误：+ ex.Message; 
}

 erroremail.Text =电子邮件已成功发送。

} 
  

I'm trying to connect to my Gmail account through SmtpClient but it seems to not work as should. I specify port 465, enable SSL and define everything, but it takes like 2 minutes and then just shows some error that the message wasn't sent.

What am I doing wrong here?

try
{
    MailMessage msg = new MailMessage();
    msg.From = new MailAddress("[e-mail]);
    msg.To.Add(new MailAddress("[e-mail]));
    msg.Subject = "This is the subject";
    msg.Body = "This is the body";
    SmtpClient sc = new SmtpClient("smtp.gmail.com", 465);
    sc.EnableSsl = true;
    sc.UseDefaultCredentials = false;
    sc.Credentials = new NetworkCredential("[e-mail]", "pass");
    sc.DeliveryMethod = SmtpDeliveryMethod.Network;
    sc.Send(msg);
    erroremail.Text = "Email has been sent successfully.";
}
catch (Exception ex)
{
    erroremail.Text = "ERROR: " + ex.Message;
}

解决方案

You need to allow "less secure apps":

Code:

try
{
    new SmtpClient
    {
        Host = "Smtp.Gmail.com",
        Port = 587,
        EnableSsl = true,
        Timeout = 10000,
        DeliveryMethod = SmtpDeliveryMethod.Network,
        UseDefaultCredentials = false,
        Credentials = new NetworkCredential("[e-mail]", "MyPassword")
    }.Send(new MailMessage {From = new MailAddress("[e-mail]", "MyName"), To = {"[e-mail]"}, Subject = "Subject", Body = "Message", BodyEncoding = Encoding.UTF8});
    erroremail.Text = "Email has been sent successfully.";
}
catch (Exception ex)
{
    erroremail.Text = "ERROR: " + ex.Message;
}
