//因為在webservice中是不能接收集合的 所以用字串接收選擇了json.//調用：List<BIZ.T_ExEntryDetailModel> ExdetailModel ExdetailModel = UPED.JsonHelper.ParseFormJson<List<BIZ.T_ExEntryDetailModel>>(jsonStr);   //解析JSON串為類  //實體類轉換JSON串為類List<Models.ExEntryDetailModel> detailModel =servers.GetExEntryDetailModel(......);string jsonStr = UPED.JsonHelper.GetJson<List<Models.ExEntryDetailModel>>(detailModel);
