    {
        MailMessage mail = new MailMessage();
        

            mail.From = new MailAddress(TextBoxEmail.Text, TextBoxCompanyName.Text);
            mail.To.Add(new MailAddress("[e-mail]"));
           
            mail.Subject = TextBoxSubject.Text;
            mail.Body = TextBoxMessage.Text;

        SmtpClient client
            = new SmtpClient("smtp.achirconsultancy.com");
        client.Credentials = new System.Net.NetworkCredential("[e-mail]", "zzzzzzzz");
        try
        {
           
            client.Port = 25;
            client.Send(mail);
        }
        catch (Exception ex) 
        {
            Labeltext.Text = " Error occured. Sorry for the inconvinence";
            return;
            /*Response.Write(" Unhandled expection occured please check the Email ID that you have entered");*/

        }

        Labeltext.Text = "Your message has been successfully sent. Thank you";
               
    }

推荐答案

您遇到什么异常?
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:

What exception you are getting?
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:

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

If needed, there are lots of article on this very site on how to send emails

是否必须在web.config中包含SMTP配置详细信息.
我很确定即使没有那也能实现.例外是连接失败.

那是不是在凭据部分中我提供了错误的详细信息?

Is it mandatory to include SMTP configuration details in web.config.
I am pretty sure I have achieved it even without that.exception was connect failure.

Is that mean the in credential section I am giving wrong details?

我在您设置客户端对象的Host属性的代码中看不到任何地方.这是必需的，以及您设置的Port属性.在此处检查. microsoft.com/en-us/library/system.net.mail.smtpclient.aspx"target =" _ blank"title =" New>

I don''t see anyplace in your code where you set the Host property of the client object. That''s required, along with the Port property that you have set. Check here[
