用反射实现数据库读出数据转化为对应的实体list

            SqlConnection con = new SqlConnection(ConnectString);
            con.Open();
            SqlCommand com = new SqlCommand(sql,con);
            SqlDataReader reader = com.ExecuteReader();
            Assembly assembly = Assembly.GetExecutingAssembly();
            var type  =assembly.GetType(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Namespace+"." + tablename);
            List<object> list = new List<object>();
            while (reader.Read())
            {
                object[] parameters= new object[1];
                parameters[0] = reader;
                var obj = assembly.CreateInstance(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Namespace + "." + tablename, true, System.Reflection.BindingFlags.Default,
       null, parameters, null, null);
                list.Add(obj);
            }
            con.Close();
            return list;
