Using LINQ To Create Custom Datatable And Travel Table

IEnumerable<DataRow> SubenumTable =
                 from goodTable in dt.AsEnumerable()
                 where goodTable.Field<string>("TravelRegion") == row.col1.ToString()
                 select goodTable;
                 //sr.Append(row.col1.ToString()+"<br>");
                foreach (DataRow goodsrow in SubenumTable)
                {
                    
                    
                    SiteNode Subn1 = new SiteNode();
                    Subn1.ParentID = count.ToString();
                    Subn1.ID = goodsrow["TravelID"].ToString();
                    Subn1.Title = goodsrow["TravelAttractions"].ToString();
                    Subn1.Pos = goodsrow["TravelLat"].ToString() + "," + goodsrow["TravelLng"].ToString();
                    nodes.Add(Subn1);
                }
