要使用html模板进行发送邮件,需要准备以下几项工作:
1)HTML模板
2)替换函数(替换模板中绑定的变量)
3)邮件函数(发送邮件)
一、HTML模板
01.<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3/TR/xhtml1/DTD/xhtml1-transitional.dtd">
02.<html xmlns="http://www.w3/1999/xhtml" >
03.<head>
04. <title>HTML Report</title>
05.</head>
06.<body>
07.<p >$USER_NAME$:</p>
08.
09.
10.<p>My name is $NAME$</p>
11.<p >This is a Test Email,<br />
12. $MY_NAME$</p>
13.</body>
14.</html>
其中USER_NAME、NAME、MY_NAME这三个变量用$符号包裹进行标识,是需要被替换的字符串,它会在下面的替换函数中被动态替换。
二、替换函数
01./// <summary>
02.///替换模板中的字段值
03./// </summary>
04.public string ReplaceText(String userName,string name,string myName)
05.{
06.
07. string path = string.Empty;
08.
09. path = HttpContext.Current.Server.MapPath("EmailTemplate\\emailTemplate.html");
10.
11. if (path == string.Empty)
12. {
13. return string.Empty;
14. }
15. System.IO.StreamReader sr = new System.IO.StreamReader(path);
16. string str = string.Empty;
17. str = sr.ReadToEnd();
18. str = str.Replace("$USER_NAME$", userName);
19. str = str.Replace("$NAME$", name);
20. str = str.Replace("$MY_NAME$",myName);
21.
22. return str;
23.}
三、邮件发送
01. /// <summary>
02. /// 发送邮件
03. /// </summary>
04. public void SendEmail(string email_from,string email_to, string email_cc, string userName, string name, string myName)
05. {
06.
07. try
08. {
09. // 建立一个邮件实体
10. MailAddress from = new MailAddress(email_from);
11.
12.
13. MailAddress to = new MailAddress(email_to);
14. MailMessage message = new MailMessage(from, to);
15.
16. string strbody = ReplaceText(userName, name, myName);
17.
18. if (email_cc.ToString() != string.Empty)
19. {
20. foreach (string ccs in email_cc.Split(';'))
21. {
22. MailAddress cc = new MailAddress(ccs);
23. message.CC.Add(cc);
24. }
25. }
26.
27. message.IsBodyHtml = true;
28. message.BodyEncoding = System.Text.Encoding.UTF8;
29. message.Priority = MailPriority.High;
30. message.Body = strbody; //邮件BODY内容
31. message.Subject = "Subject";
32.
33. SmtpClient smtp = new SmtpClient();
34. smtp.Host = Configuration.MailHost;
35. smtp.Port = Configuration.MailHostPort;
36. smtp.Credentials = new System.Net.NetworkCredential(email_from, "emailpassword");
37.
38. smtp.Send(message); //发送邮件
39.
40. } catch (Exception ex)
41. {
42. throw ex;
43. }
44.
45. }
其实无论采取什么方式或组件进行邮件发送,要替换HTML模板中的内容,只需一个Replace函数即可。
