提交表格

我需要在用户单击提交按钮时通过电子邮件发送此内容。我把这个文件保存为.html。我是asp.net新手。请帮助我如何发送电子邮件。来自电子邮件的id将是固定的（例如：test@domainname.com)

You can send email following way in ASP.NET.

 protected string SendEmail(string toAddress, string subject, string body)
   {
     string result = “Message Sent Successfully..!!”;
     string senderID = “SenderEmailID“;// use sender’s email id here..
     const string senderPassword = “Password“; // sender password here…
     try
     {
       SmtpClient smtp = new SmtpClient
       {
         Host = “smtp.gmail.com“, // smtp server address here…
         Port = 587,
         EnableSsl = true,
         DeliveryMethod = SmtpDeliveryMethod.Network,
         Credentials = new System.Net.NetworkCredential(senderID, senderPassword),
          Timeout = 30000,
       };
       MailMessage message = new MailMessage(senderID, toAddress, subject, body);
       smtp.Send(message);
     }
     catch (Exception ex)
     {
       result = “Error sending email.!!!”;
     }
     return result;
    }
