- Make sure that you have a smtp server setup. 确保您具有smtp服务器设置。 add smtp server info in web.config. 在web.config中添加smtp服务器信息。 then try this. 然后尝试这个。
you need to mention the smtp server url and the port number. 你需要提到smtp服务器url和端口号。 SMTp SMTP
SmtpClient obj = new SmtpClient(yourSmtpServerURL);
NetworkCredential myCreds = new NetworkCredential("youremail@gmail.com", "YourPassword", "");
obj.Credentials = myCreds;
then now call obj.send . 然后现在调用obj.send 。

There may be two cause: 可能有两个原因：
This usually results from trying to connect to a service that is inactive on the foreign host.
这通常是因为尝试连接到在外部主机上处于非活动状态的服务。 Sometimes a 10061 error is caused by either a firewall or anti-virus software presence on the local computer or network connection.
有时，本地计算机或网络连接上的防火墙或防病毒软件存在会导致10061错误。
Either one may be blocking the ports needed to make a successful connection to the server. 任何一个都可能阻塞成功连接到服务器所需的端口。 Either you went to the wrong host, or the server application you're trying to contact is not executing. 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。 Check the destination address you are using. 检查您使用的目标地址。 Check, if you used a hostname, did it resolve to the correct address or not.. 如果您使用了主机名，请检查是否已解析为正确的地址。

You can apply SMTP settings in web.config by putting this section inside: 您可以通过将此部分放在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>
This example shows configuration for Gmail SMTP server. 此示例显示Gmail SMTP服务器的配置。

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);

You have to give credentials.. check the below code once 您必须提供凭据..请检查以下代码一次
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);
You have to add below namespaces 您必须添加以下命名空间
using System.Net.Mail;
using System.Net;
