How to Send Email From Website Asp.Net C#.Net

 How to Send Email from website

Task: Send Email Notification using c# code in asp.net website/web application.

Description: Many times we want to send auto email to our website viewer or website owner. As we require after the viewer of website submits any enquiry then it should be come immediate in email Inbox Or In E-Commerce website after successfully purchasing any item a auto email notification will be send to customer (billing detail) and as well as website administrator also.

So that I use two variation of code for sending email as shown below. For this we require a email account and password for authentication.

First one is require your any one email account, password and mail server detail. The second one is for using gmail account.

using System.Web.Mail;
 public bool mailsend(string sSubject, string sBody, string sMailFrom, string sToMail)
    {
        try
        {
            MailMessage sMail = new System.Web.Mail.MailMessage();
            sMail.To = sToMail.ToString();
            sMail.From = sMailFrom.ToString();
            sMail.Subject = sSubject.ToString();
            sMail.Body = sBody.ToString();
            sMail.Priority = MailPriority.High;
            sMail.BodyFormat = MailFormat.Html;
            SmtpMail.SmtpServer = "mail.website.com"; // your mail server name

          sMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");  //basic authentication
          sMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "emailid");  //set your username here
          sMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "password");  //set your password here
            SmtpMail.Send(sMail);
            return true;
        }
        catch (Exception ex)
        {
           return false;
        }
    }

// using by gmail/smtp email id for authentication
 public bool mailsend(string to, string sub, string msg, string replyto)
    {
        string from = "yourmailid@gmail.com"; //Replace this with your own correct Gmail/Email Address
        string pwd = "password"; // Replace this with your above email id password.
        bool status = false;
        System.Net.Mail.MailMessage email = new System.Net.Mail.MailMessage();
        email.To.Add(to);
        email.From = new System.Net.Mail.MailAddress(to, "Client", System.Text.Encoding.UTF8);
        string mailbody = msg;
        email.Subject = sub;

        email.ReplyTo = new System.Net.Mail.MailAddress(replyto,"", System.Text.Encoding.UTF8);

        email.SubjectEncoding = System.Text.Encoding.UTF8;
        email.Body = mailbody;
        email.BodyEncoding = System.Text.Encoding.UTF8;
        email.IsBodyHtml = true;
        System.Net.Mail.SmtpClient emailclient = new System.Net.Mail.SmtpClient();
        emailclient.Credentials = new System.Net.NetworkCredential(from, pwd);
        emailclient.Port = 587; // Gmail works on this port
        emailclient.Host = "smtp.gmail.com"; // Your SMTP MailServer
        emailclient.EnableSsl = true; //Gmail works on Server Secured Layer
        try
        {
            emailclient.Send(email);
            status = true;
            return (status);
        }
        catch (Exception ex)
        {
            status = false;
            return (status);
        }
    }
