dynamic動態添加屬性

 List<dynamic> list = conn.Query(srhsql, p).ToList(); //查出數據
 List<dynamic> tmp = new List<dynamic>();
 foreach (var row in list)
{
                        dynamic info = new System.Dynamic.ExpandoObject();
                        var dic = (IDictionary<string, object>)info;
                        foreach (KeyValuePair<string, object> col in row)
                        {
                            dic.Add(col);
                        }
                        dic.Add("bkap", bukaoExist(conn, row.term, row.courseid, row.stid));
                        tmp.Add(info);
                    }
                    list = tmp;
               

定義一個System.Dynamic.ExpandoObject對象，轉成IDictionary，就可以添加屬性了
