asp.net 使用html模板发送电子邮件

2013-05-16 17:28 543 查看

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;
}
