发送电子邮件时出错 [英] Error in sending Email

问题描述

当我尝试向已注册的电子邮件发送电子邮件时忘记密码页面，然后我收到此错误：

SMTP服务器需要安全连接或客户端未经过身份验证。服务器响应是需要验证。





代码是：

When I was trying to Send an Email to Registered email Id In forgot Password Page ,then i got this Error:
The SMTP server requires a secure connection or the client was not authenticated. The server response was Authentication Required.


Code Is:

public void Sendemail()
  {
          MailMessage message = new MailMessage();
          message.From = new MailAddress("[e-mail]", "admin");
          message.To.Add(Usertxt.Text);
          message.Subject = "Verification Email";
          message.Body = "Your Password is";
          message.IsBodyHtml = true;
          SmtpClient smtp = new SmtpClient();
          smtp.Host = "smtp.gmail.com";
          smtp.Port = 587;
          smtp.Credentials = new System.Net.NetworkCredential("[e-mail]", "admin123");
          smtp.EnableSsl = true;
          smtp.Send(message);
  }

推荐答案

试试这个...





MailMessage message = new MailMessage（）;

MailAddress fromAddress = new MailAddress（[e-mail]）;



message.From = fromAddress;

message.To.Add（Usertxt.Text）;





message.Subject =验证电子邮件;

message.IsBodyHtml = true;





SmtpClient smtpClient = new SmtpClient（smtp.gmail.com ）;

smtpClient.Port = 587;

smtpClient.EnableSsl = true;

smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;



smtpClient.UseDefaultCredentials = false;



smtpClient.Credentials = new System.Net.NetworkCredential（admin @ gmail .com，admin123）;



smtpClient.Send（message）;

Try This...


MailMessage message = new MailMessage();
MailAddress fromAddress = new MailAddress("[e-mail]");

message.From = fromAddress;
message.To.Add(Usertxt.Text);


message.Subject = "Verification Email";
message.IsBodyHtml = true;


SmtpClient smtpClient = new SmtpClient("smtp.gmail.com");
smtpClient.Port = 587;
smtpClient.EnableSsl = true;
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;

smtpClient.UseDefaultCredentials = false;

smtpClient.Credentials = new System.Net.NetworkCredential("[e-mail]", "admin123");

smtpClient.Send(message);

我认为您使用的凭据不对。请再次验证。



请参考我之前的答案，并提供完整的工作示例 - 从asp.net发送电子邮件到gmail [ ^ ]

I think the credentials you are using are incorrect. Please verify once again.

Refer my previous answer with a fully working example - sending email to gmail from asp.net[^]

引用电子邮件错误：SMTP服务器需要安全连接或客户端未经过身份验证。服务器响应为：5.5.1需要验证 [ ^ ]
