使用 Gmail 设置发送电子邮件时出现问题

本文关键字：问题 电子邮件 Gmail 设置 使用 | 更新日期: 2023-09-27 17:48:54

我无法使用 Gmail 设置发送电子邮件。 我已经尝试过客户端。主机 ="本地主机" 它正在工作，但不在客户端中。主机 ="smtp.gmail.com"..请帮助我伙计们..我需要使用客户端。主机 ="smtp.gmail.com"..谢谢

这是我的 C# 代码：

string from =  "aevalencia119@gmail.com"; //Replace this with your own correct Gmail Address
string to = "aevalencia191@gmail.com";  //Replace this with the Email Address  to whom you want to send the mail
 System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage(); 
 mail.To.Add(to);  mail.From = new
 MailAddress(from, "One Ghost" ,System.Text.Encoding.UTF8);
 mail.Subject = "This is a test mail" ;
 mail.SubjectEncoding = System.Text.Encoding.UTF8; mail.Body =  "This is Email Body Text";
 mail.BodyEncoding = System.Text.Encoding.UTF8;
 mail.IsBodyHtml = true ; mail.Priority = MailPriority.High;
 SmtpClient client = new SmtpClient();  //Add the Creddentials- use your own email id and password
  client.Credentials = new System.Net.NetworkCredential(from, "iseedeadpoeple");
 client.Port = 587; // Gmail works on this port client.Host ="smtp.gmail.com";         
 client.EnableSsl = true; //Gmail works on Server Secured Layer
        try
         {
             client.Send(mail);
         }
         catch (Exception ex) 
         {
             Exception ex2 = ex;
             string errorMessage = string.Empty; 
             while (ex2 != null)
             {
                 errorMessage += ex2.ToString();
                 ex2 = ex2.InnerException;
             }    HttpContext.Current.Response.Write(errorMessage
);
         } // end try

这是错误：

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

非常感谢大家！

使用 Gmail 设置发送电子邮件时出现问题

您需要

使用 SSL 安全证书获取邮件并将其发送到 GMail 

MailMessage msgMail = new MailMessage("a@gmail.com", "b@mail.me", "subject", "message body");
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new System.Net.NetworkCredential("a@gmail.com", "a");
try
{
   smtp.Send(msgMail);
}
catch (Exception ex)
{
}
