Question

创建用户帐户时，尝试发送包含密码的电子邮件。（在How to send email from Asp.net Mvc-3?

的帮助下

public void SendEmail(string address, string subject, string message, string password)
    {
        string email = "emailAddress";
        //string password = "put-your-GMAIL-password-here";

        var loginInfo = new NetworkCredential(email, password);
        var msg = new MailMessage();
        var smtpClient = new SmtpClient("smtp.gmail.com", 587);

        msg.From = new MailAddress(email);
        msg.To.Add(new MailAddress(address));
        msg.Subject = subject;
        msg.Body = message;
        msg.IsBodyHtml = true;

        smtpClient.EnableSsl = true;
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = loginInfo;
        smtpClient.Send(msg);
    }

但是smtpClient.Send（msg）;返回以下错误：

{System.Net.Mail.SmtpException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at
   at System.Net.Mail.MailCommand.CheckResponse(SmtpStatusCode statusCode, String response)
   at System.Net.Mail.MailCommand.Send(SmtpConnection conn, Byte[] command, MailAddress from, Boolean allowUnicode)

   at ACCS.StockControl.Controllers.UserLoginRecordController.SendEmail(String address, String subject, String message, String password)
   at ACCS.StockControl.Controllers.UserLoginRecordController.EditModalPOST(UserLoginRecordEditModalVM model)}

任何想法？

Answer 1

可能只是密码和用户名错误。

请尝试使用其他假密码（例如“thisPasswordIsSurelyDontWork”）。如果您的例外情况相同，那么您必须检查您的信用卡，用户名，密码

//或尝试

 smtpClient.UseDefaultCredentials = true;

Answer 2

 MailMessage loginInfo = new MailMessage();
 loginInfo.To.Add("Emailaddress");
 loginInfo.From = new MailAddress("FromEmailaddress");
 loginInfo.Subject = "Subject";
 loginInfo.Body = "Body of the mail";
 loginInfo.IsBodyHtml = true;

 SmtpClient smtp = new SmtpClient();
 smtp.Host = hostname;
 smtp.Port = 25; //in my case i am using 25
 smtp.EnableSsl = false; //enable ssl is set to false
 smtp.Credentials = new System.Net.NetworkCredential(sEmailId, sPassword);
 smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
 smtp.Send(loginInfo);
 {
   Label.Visible = true;
   Label.Text = "A mail has been sent to you with the your username. Please check your inbox.";
 }

Answer 3
