C# Email邮件发送功能 找回或重置密码功能

最近根据公司需求，写个邮件发送。这里面的传入的地址信息的参数都是经过加密的，主要是保证用户信息的安全。

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+)*"))
   {
    return content("0");
   }
   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)
    {
     return content("true");
    }
    else
    {
     return content("false");
    }
   }
   else {
    return content("false");
   }
  }
