            smtpClient.Port = 1159;

            //From address will be given as a MailAddress Object
            message.From = fromAddress;

            // To address collection of MailAddress
            message.To.Add("admin1@yoursite.com");
            message.Subject = "Feedback";

            // CC and BCC optional

            message.Body = txtMessage.Text;

            // Send SMTP mail
            smtpClient.Send(message);

            lblStatus.Text = "Email successfully sent.";
        }
        catch (Exception ex)

        txtName.Text = "";
        txtMessage.Text = "";
        txtEmail.Text = "";
    }
    #endregion
}

im getting the error here 我在这里得到错误

 // Send SMTP mail
 smtpClient.Send(message);

i dont know how to correct it. 我不知道如何纠正它。 my port no is 3168 i had tried to replace it. 我的端口号是3168，我曾尝试更换它。 but unable to resolve 但无法解决

the catch portion is getting "Failure sending Mail" im sending the detail/snapshort of error. 捕获部分正在“发送邮件失败”，即发送错误的详细信息/快照。

Right off the bat, I would say that your problem is the fact you have set localhost as your mail server. 马上，我想说您的问题是您已将localhost设置为邮件服务器。 Do you even have a mail server installed locally? 您甚至在本地安装了邮件服务器？ If you have access to a real mail server on your live site, try setting the mail server to that address with appropriate password and username info. 如果您可以访问实时站点上的真实邮件服务器，请尝试使用适当的密码和用户名信息将邮件服务器设置为该地址。 Then see if them mail goes out. 然后查看他们的邮件是否发送出去。
