smtp.Host = "smtp.163.com";//设置SMTP服务器地址（用于发送邮件的邮箱的SMTP服务器地址）

smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;

smtp.DeliveryMethod = SmtpDeliveryMethod.Network; //递送方法为网络
smtp.Send(mail);

}
catch (Exception ex)
{

log = ex.Message;
string errorPath = "E:\\" + "error.log";
if (!File.Exists(errorPath))
{
FileStream create = File.Create(errorPath);
create.Close();
}
FileStream fs = new FileStream(errorPath, FileMode.Append, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.WriteLine("Exception： " + ex.Message + " --" + DateTime.Now.ToString());
sw.Flush();
sw.Close();
fs.Close();
}
}

return IsSuccess;

}
