Question

ArrayList al = new ArrayList();
var sid = (from transaction in doc.Descendants("transaction")
           from tenderdetails in transaction.Elements("tenderdetail")
           where (int)tenderdetails.Element("tendertype") == 13

           select new
           {
               storeID = (string)transaction.Element("storeid"),
           }).Distinct();



al.AddRange((from transaction in doc.Descendants("transaction")
             from tenderdetails in transaction.Elements("tenderdetail")
             where (int)tenderdetails.Element("tendertype") == 13

             select new
             {
                 tendertype = (string)tenderdetails.Element("tendertype"),
                 storeID = (int)transaction.Element("storeid"),
                 tDate = (string)transaction.Element("date"),
                 sTime = Convert.ToString(vdt.GetValidDateTime((string)transaction.Element("time")) + ".000"),
                 etime = Convert.ToString(vdt.GetValidDateTime((string)transaction.Element("endTime")) + ".000"),
                 strans = vdt.GetValidDate((string)transaction.Element("date"), "yyyymmdd") + " " + Convert.ToString(vdt.GetValidDateTime((string)transaction.Element("time")) + ".000"),
                 etrans = vdt.GetValidDate((string)transaction.Element("date"), "yyyymmdd") + " " + Convert.ToString(vdt.GetValidDateTime((string)transaction.Element("endTime")) + ".000"),
                 totalAmount = (string)transaction.Element("totalamt"),
              ).ToList());

结果：

tendertype = 13，storeID = 1830020，tDate = 20180628，sTime = 13：30：36.000，etime = 13：30：40.000，strans = 2018-06-28 13：30：36.000，etrans = 2018-06- 28 13：30：40.000，totalAmount = 4700} {投标类型= 13，storeID = 1830020，tDate = 20180628，sTime = 15：35：15.000，etime = 15：35：23.000，strans = 2018-06-28 15:35 ：15.000，etrans = 2018-06-28 15：35：23.000，totalAmount = 3400}

我的问题是我可以向这些arraylist对象添加更多值

如何将新值附加到现有...。arraylist对象c＃
