Answer 1

确保您已安装smtp服务器。在web.config中添加smtp服务器信息。然后尝试这个。

您需要提及smtp服务器URL和端口号。 SMTp

   SmtpClient obj = new SmtpClient(yourSmtpServerURL);
 NetworkCredential myCreds = new NetworkCredential("youremail@gmail.com", "YourPassword", "");           
            obj.Credentials = myCreds;

然后现在拨打obj.send。

Answer 2

可能有两个原因：

这通常是因为尝试连接到的服务在外国主机上不活跃。
有时10061错误是由防火墙或防病毒引起的本地计算机或网络连接上的软件存在。

任何一个都可能阻塞了与服务器成功连接所需的端口。要么你去了错误的主机，要么你正在尝试联系的服务器应用程序没有执行。检查您使用的目标地址。如果您使用了主机名，请检查它是否已解析为正确的地址..

Answer 3

确保在网络配置文件

上设置smtp

<system.net>
<mailSettings>
  <smtp>
    <network host="smtp@server" port="25" userName="user" password="password" defaultCredentials="true" />
  </smtp>
</mailSettings>
 </system.net>

Answer 4

您可以将此部分放在web.config中来应用SMTP设置：

    <system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="...">
        <network host="smtp.gmail.com" port="587" defaultCredentials="false" userName="" password="" enableSsl="true" />
      </smtp>
    </mailSettings>
  </system.net>

此示例显示Gmail SMTP服务器的配置。

Answer 5

System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.Subject = "Title";
message.From = new System.Net.Mail.MailAddress(yourEmailExpeditor);
message.Body = "content message here";

//Initialize the smtp
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient(adress,int.Parse(port));
//Send the message
smtp.Send(message);

Answer 6

您必须提供凭据..请检查以下代码

        MailAddress to = new MailAddress("Email Id");

        MailAddress from = new MailAddress("Email Id");

        MailMessage mail = new MailMessage(from, to);

        mail.Subject = "";
        mail.Body = "";


        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;

        smtp.Credentials = new NetworkCredential(
            "Email Id", "Password");
        smtp.EnableSsl = true;

        smtp.Send(mail);

您必须添加以下命名空间

using System.Net.Mail;
using System.Net;

通过asp.net发送电子邮件
