C#. NET uses HTML templates to send full instances of e-mail

The examples in this article describe C #. NET using HTML templates to send e-mail messages is a very practical technique. Share to everyone for your reference. Here's how:

To send a message using an HTML template, you need to prepare the following tasks:

1) HTML templates

2) Replace function (replace the bound variable in the template)

3) Mail function (send mail)

First, HTML templates

<! DOCTYPE HTML PUBLIC "-//W3C//DTD XHTML 1.0 transitional//en" "Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd ">
The three variables, user_name, NAME, and My_name, are identified with the $ symbol package, which is a string that needs to be replaced, which is replaced dynamically in the replacement function below.

Second, replace the function
<summary>///Replace the field values in the template//</summary>public string ReplaceText (String username,string name,string MyName) {  string path = string. Empty;  Path = HttpContext.Current.Server.MapPath ("emailtemplate\\emailtemplate.html");  if (Path = = String. Empty)  {    return string. Empty;  }  System.IO.StreamReader sr = new System.IO.StreamReader (path);  String str = string. Empty;  str = Sr. ReadToEnd ();  str = str. Replace ("$USER _name$", userName);  str = str. Replace ("$NAME $", NAME);  str = str. Replace ("$MY _name$", myName);  return str;}

Third, the Mail sent
<summary>///Send mail///</summary>public void SendEmail (String email_from,string email_to, String email_cc , string userName, string name, String myName) {try {//build a mail entity mailaddress from = new MailAddress (email_from); MailAddress to = new MailAddress (email_to); MailMessage message = new MailMessage (from, to); String strbody = ReplaceText (userName, name, myName); if (email_cc. ToString ()! = string. Empty) {foreach (String CCS in EMAIL_CC.   Split (';')) {mailaddress cc = new MailAddress (CCS); message. Cc.   ADD (CC); }} message. Isbodyhtml = true; Message. bodyencoding = System.Text.Encoding.UTF8; Message. priority = Mailpriority.high; Message. Body = strbody; The message body content message. Subject = "Subject"; SmtpClient smtp = new SmtpClient (); Smtp. Host = Configuration.mailhost; Smtp. Port = Configuration.mailhostport; Smtp. Credentials = new System.Net.NetworkCredential (Email_from, "Emailpassword"); Smtp. Send (message);  Send mail} catch (Exception ex) {throw ex; }}
In fact, no matter what way or component to send the message, to replace the content in the HTML template, just a replace function.
