推荐答案

可能是由于各种原因.您需要一一看待它们.
港口开放吗?防火墙权限到位了吗?
进一步确保已在Web.Config中配置SMTP配置:

It can be because of various reasons. You need to look at them one by one.
Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="[e-mail]">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>

如果需要，请查看此Microsoft Video教程:
使用ASP.NET发送来自网站的电子邮件 [

If needed, have a look at this Microsoft Video tutorial:
Use ASP.NET to send Email from Website[^]

如果您使用"smtp.yahoo.com"服务，则必须分配端口不，您的Yahoo地址和SmtpClient对象上的密码.

或者，您也可以通过您的gmail帐户发送邮件.

使用ASP.net通过Gmail帐户(Gmail SMTP服务器帐户)发送电子邮件 [ ^ ]

If you use "smtp.yahoo.com" service you''ll have to assign the Port No, your yahoo address and the password on you SmtpClient object.

Or you also can send mail through your gmail account.
