            catch
            ...{
                isSuccess = false;
            }
        }
        return isSuccess;
    } 
}

 

调用发信函数

 

         if  (sendMail.Send( " ycyangcai@163.com " ,  " ycyangcai@163.com " ,  " subject " ,  true ,  " body " ,  " smtp.163.com " ,  " yangcai " ,  " yangcai " ))
         ... {
            Response.Write("ok");
        }
         else
         ... {
            Response.Write("no");
        }
