ASP.NET 上的操作超时错误

Question

我在通过 asp.net SMTP 服务器发送电子邮件时遇到错误。它说操作已超时。如何克服异常？

   try
    {
        MailMessage mail = new MailMessage();
        SmtpClient SmtpServer = new SmtpClient();

        mail.From = new MailAddress("mymailid@hotmail.com");
        mail.To.Add("yourmailid@gmail.com");
        mail.Subject = "Verify your account";
        mail.Body = "Your OTP for your account verification is "+OTP.ToString()+". Enter your OTP in verification window.";
        mail.IsBodyHtml = true;

        SmtpServer.UseDefaultCredentials = false;
        SmtpServer.Timeout = 20000;
        SmtpServer.Send(mail);
        errmsgShow.Text = "Mail sent";
    }
    catch (Exception e)
    {
        //string errMsg = "alert('OTP sending failed. Error: " +e.ToString()+ "')";
        //ScriptManager.RegisterClientScriptBlock(Page, typeof(Page), "ClientScript", errMsg, true);
        //Console.WriteLine(e.Message.ToString());
        errmsgShow.Text = e.ToString();
    }

我也在下面的web.config中包含了

<system.net>
<mailSettings>
  <smtp deliveryMethod="Network">
    <network host="smtp.live.com" port="25" userName="mymailid@hotmail.com" password="password" enableSsl="true"/>
  </smtp>
</mailSettings>
</system.net>

Answer 1

尝试删除SmtpServer.Timeout = 20000;。

更新：

我看到你有SmtpClient SmtpServer = new SmtpClient();。

SmtpServer 是 SmtpMail SmtpMail.SmtpServer 的属性。尝试更改变量名称，例如

SmtpClient mailClient = new SmtpClient();
