好的，我希望这有帮助。我这样做的方式是解析Xml并将其加载到DOM（这里我使用的是LinqToXml），然后尝试查找所有座位并将它们插入到DataTable的实例中

你正在使用的数据库引擎是什么？我没有使用任何xml字符串获取其他API（响应）的数据库。我只是想理解一下。所以您只需要将Xml字符串转换为DataTable类型？是的，但我需要以下列：列、行、座位、甲板、状态。这意味着1、1、1c、1、0谢谢Rikki的帮助。
public static DataTable querySeat(string bus_id)
{
DataTable dt = new DataTable();
DataColumn dc;
dc = new DataColumn("column", Type.GetType("System.Int32"));
dt.Columns.Add(dc);
dc = new DataColumn("row", Type.GetType("System.Int32"));
dt.Columns.Add(dc);
dt.Columns.Add("seat"); // Seat Label
dc = new DataColumn("deck", Type.GetType("System.Int32")); // Deck, 1 = Lower Deck, 2 = Upper Deck
dt.Columns.Add(dc);
dt.Columns.Add("status"); // Status, 1 = Available, 0 = Taken
return dt;
