webconfig配置信息
1 <add key="EmailName" value="××××@163.com"/> 2 <add key="EmailPass" value="××××"/> 3 <add key="EmailService" value="smtp.163.com"/> 4 5 //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
1 public ActionResult SendEmail(string EmailName) 2 { 3 EmailName = Helper.FI_DesTools.DesDecrypt(EmailName); 4 if (!Regex.IsMatch(EmailName, @"\w+([-+.‘]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*")) 5 { 6 return Content("0"); 7 } 8 string f_username = ""; 9 string f_pass = ""; 10 string f_times = Helper.FI_DesTools.DesEncrypt(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")); 11 List<user> list = (from a in users where a.emailaddress == EmailName select a).ToList(); 12 if (list.Count > 0) 13 { 14 f_username = Helper.FI_DesTools.DesEncrypt(list[0].×××); 15 f_pass = Helper.FI_DesTools.DesEncrypt(list[0].×××); 16 17 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 18 if (flag) 19 { 20 return Content("true"); 21 } 22 else 23 { 24 return Content("false"); 25 } 26 } 27 else { 28 return Content("false"); 29 } 30 }
