webconfig配置信息
<add key= "EmailName" value= "××××@163.com" />
<add key= "EmailPass" value= "××××" />
<add key= "EmailService" value= "smtp.163.com" />
//说明： 这里面的"EmailService"得与你自己设置邮箱的smtp/POP3/...服务要相同， 大部分是根据@后面的进行配置。我是用163邮箱配置的。 可以根据自己需要自己配置。
后台调用的方法
public ActionResult SendEmail( string EmailName)
{
EmailName = Helper.FI_DesTools.DesDecrypt(EmailName);
if (!Regex.IsMatch(EmailName, @"\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" ))
{

}
string f_username = "" ;
string f_pass = "" ;
string f_times = Helper.FI_DesTools.DesEncrypt(DateTime.Now.ToString( "yyyy-MM-dd HH:mm:ss" ));
List<user> list = (from a in users where a.emailaddress == EmailName select a).ToList();
if (list.Count > 0)
{
f_username = Helper.FI_DesTools.DesEncrypt(list[0].×××);
f_pass = Helper.FI_DesTools.DesEncrypt(list[0].×××);
bool flag = Helper.MailService.SendEmailDefault(EmailName, [×××],[×××], [×××]); //这里面的参数根据自己需求自己定，最好进行加密
if (flag)

}
