const string subject = "job recommendation";

} 
} 

<add key="emailaddress" value="**********@gmail.com"/>//email address 
<add key="emailpassword" value="*********"/> //emial pwd 
<add key="smtpserver" value="smtp.gmail.com"/>

<--带附件版本->

//如果没有路径，用stream

//如果希望通过匿名邮件发送 则 

var smtp = new smtpclient 
{

port = 25, //匿名发送端口 
enablessl = false, 
deliverymethod = smtpdeliverymethod.network, 
usedefaultcredentials = false,

};
