asp.net 施用html模板发送电子邮件 _HTML/CSS

asp.net 使用html模板发送电子邮件

在做一个基于ASP.NET的项目时需要使用html模板发送电子邮件，研究了下，总结如下：

HTML模板

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head>
    <title>HTML Template</title>
</head>
<body>
<p >Dear $USER_NAME$,</p>


<p>My name is $NAME$</p>
<p >Best Regards,<br />
  $MY_NAME$</p>
</body>
</html>

其中用$符号包裹的字符串是要在程序里动态替换的。

发送邮件

        /// <summary>
        /// 发送邮件
        /// </summary>
        public void SendEmail(string email_from,string email_to, string email_cc, string userName, string name, string myName)
        {

            try
            {
                // 建立一个邮件实体
                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;
                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);

            } catch (Exception ex)
            {
                throw ex;
            }

        }

替换HTML模板中的字段值

        /// <summary>
        ///替换模板中的字段值
        /// </summary>
        public string ReplaceText(String userName,string name,string myName)
        {

            string path = string.Empty;
         
            path = HttpContext.Current.Server.MapPath("Email_Template\\email.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;
        }

THE END
