从XML中读取数据到内存的实例

从XML中读取数据到内存的实例：

public clsSimuResultByOneGoods GetOneGoodsSimulationXML(string PathAndFileName)
        {
            clsSimuResultByOneGoods OneGoods = new clsSimuResultByOneGoods();//自己定义的一个类
            Hashtable AllLocationResult = new Hashtable();
            System.Xml.XmlTextReader r = new XmlTextReader(PathAndFileName);
            string LocationID = "";
            DataTable LocationTable = null;
            while(r.Read())
            {
                if(r.NodeType == XmlNodeType.Element)
                {
                    switch(r.LocalName)
                    {
                        case "Result":
                            OneGoods.GoodsCode = r.GetAttribute("GoodsCode");
                            OneGoods.From = Convert.ToDateTime(r.GetAttribute("FromDate"));
                            OneGoods.To = Convert.ToDateTime(r.GetAttribute("ToDate"));
                            break;
                        case "Location":
                            LocationID = r.GetAttribute("ID");
                            LocationTable = new DataTable();
                            LocationTable.Columns.Add("Date",typeof(DateTime));
                            LocationTable.Columns.Add("SafetyStock",typeof(decimal));
                            LocationTable.Columns.Add("ForecastDemand",typeof(decimal));
                            LocationTable.Columns.Add("FinalOutput",typeof(decimal));
                            LocationTable.Columns.Add("FinalInput",typeof(decimal));
                            LocationTable.Columns.Add("SimuStock",typeof(decimal));
                            LocationTable.Columns.Add("SimuStockTime",typeof(decimal));
                            LocationTable.Columns.Add("ImportWorkDay",typeof(bool));
                            LocationTable.Columns.Add("ImportWorkDay",typeof(bool));
