Question

此联系表单的后端使用C＃，而html是前端

   using System;
   using System.Collections.Generic;
   using System.Linq;
   using System.Web;
   using System.Web.UI;
   using System.Web.UI.WebControls;
   using System.Net.Mail;

   public partial class index : System.Web.UI.Page
   {
         protected void Send_Click(object sender, EventArgs e)
         {
              try
              {
                   MailMessage message = new MailMessage(From.Text, To.Text, Subject.Text, Body.Text);
                   message.IsBodyHtml = true;
                   SmtpClient client = new SmtpClient("smtp.gmail.com", 465);
                   client.EnableSsl = true;
                   // The credentials when I ran the code were correct.
                   client.Credentials = new System.Net.NetworkCredential("example@gmail.com","password");

                   client.Send(message);

                   status.Text = "Mail was sent successfully";
                   status.Text = "Send was clicked";
              }
              // This catch block is so that you can see what error 
              // occurs if there is an error
              catch(Exception ex)
              {
                 status.Text = ex.StackTrace;
              }
       }
 }

这是显示的错误

System.Net.Mail.MailCommand.CheckResponse（SmtpStatusCode statusCode，字符串响应）

在System.Net.Mail.MailCommand.Send（SmtpConnection conn，Byte []命令，来自的MailAddress，布尔值allowUnicode）
  在System.Net.Mail.SmtpTransport.SendMail（MailAddress发件人，MailAddressCollection收件人，字符串deliveryNotify，布尔值allowUnicode，SmtpFailedRecipientException＆异常）
  在System.Net.Mail.SmtpClient.Send（MailMessage消息）处位于C：\ Users \ robert.crider \ source \ repos \ WebSite2 \ WebSite2 \ index.aspx.cs：line中index.Send_Click（Object sender，EventArgs e）处37

请确保您为Google SMTP和传送网络使用正确的端口。并且您已经在Gmail帐户设置中启用 IMAP和/或POP3访问。

SmtpClient client= new SmtpClient
        {
           Host = "smtp.gmail.com",
           Port = 587,
           EnableSsl = true,
           DeliveryMethod = SmtpDeliveryMethod.Network,
           Credentials    = new NetworkCredential(yourgoogleemail, yourgooglepassword),
           Timeout = 3000
        };

我想通过ASP.NET发送邮件，但发生错误
