讀取具有多個子節點的xml文件只會返回第一個節點

Question

我有一個帶名稱空間的xml文件，我可以正確讀取它。它有一個名為'Items'的外部節點，其中有多個子節點，其中有50個子節點（因此50個子節點稱為'ReceiverPoints'）。當我檢查控制台，它的大小是正確的，即50，但是當我檢查打印輸出時，所有輸出都是第一個ReceiverPoint節點的重復。

我想將每個接收器點保存到數據庫中。根據我所看到的所有示例，我的實現看起來不錯。但是它給了我錯誤的結果。有人可以幫我看看我所缺少的是什么嗎？這是xml文件

public List<ReceiverPoint> ReadFile()
    {
        receiverList = new List<ReceiverPoint> ();

        Console.WriteLine ("Now in read file method :" + fileLocation);

            xmldoc = new XmlDocument ();
            xmldoc.Load (fileLocation);

        XmlNamespaceManager nameSpaceManager = new XmlNamespaceManager (xmldoc.NameTable);

        //nameSpaceManager.AddNamespace ("ns", "http://schemas.datacontract.org/2004/07/AristotleService.Models");
        nameSpaceManager.AddNamespace ("ns", "http://schemas.datacontract.org/2004/07/GTI.Aristotle.Web.Api.Models");



        XmlElement rootElement = xmldoc.DocumentElement;

        XmlNodeList nodeList = rootElement.SelectNodes("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint", nameSpaceManager);

        ReceiverPoint receiverPoint = new ReceiverPoint ();
foreach(XmlNode childNode in nodeList)
        {
            receiverPoint.CloseDate = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:CloseDate", nameSpaceManager).InnerText;

            receiverPoint.IsDeployed = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:IsDeployed", nameSpaceManager).InnerText; 
            receiverPoint.IsManual = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:IsManual", nameSpaceManager).InnerText;
            receiverPoint.LastModifyDate = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:LastModifyDate", nameSpaceManager).InnerText;
            receiverPoint.Latitude = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:LatitudeWGS84", nameSpaceManager).InnerText;
            receiverPoint.Line = childNode.SelectSingleNode ("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint/ns:Line", nameSpaceManager).InnerText;

            //Get all the values stored in the receiver point object
            string station = receiverPoint.Station;

            string createWho = receiverPoint.CreateWho;
            string lastModifyDate = receiverPoint.LastModifyDate;


            Console.WriteLine ("String lat : " + latitude);

            Console.WriteLine ("String lon : " + longitude);

            Console.WriteLine ("String create date : " + createDate);

            Console.WriteLine ("String create who : " + createWho);

            //Save the data to the db
            saveDataToDatabase (station,line,elevation,latitude,longitude,isDeployed,easting,receiverType,closeDate,createDate,createWho,lastModifyDate);


        }

        receiverList.Add (receiverPoint);
return receiverList;
    }

該代碼對我有用：

public List<ReceiverPoint> ReadFile()
        {
            var receiverList = new List<ReceiverPoint>();

            Console.WriteLine("Now in read file method :" + "");

            var xmldoc = new XmlDocument();
            xmldoc.Load(@"D:\users\..\Downloads\ReceiverPoints.xml");

            XmlNamespaceManager nameSpaceManager = new XmlNamespaceManager(xmldoc.NameTable);

            //nameSpaceManager.AddNamespace ("ns", "http://schemas.datacontract.org/2004/07/AristotleService.Models");
            nameSpaceManager.AddNamespace("ns", "http://schemas.datacontract.org/2004/07/GTI.Aristotle.Web.Api.Models");



            XmlElement rootElement = xmldoc.DocumentElement;

            XmlNodeList nodeList = rootElement.SelectNodes("/ns:PagedDataInquiryResponseOfReceiverPointQ3ffICf5/ns:Items/ns:ReceiverPoint", nameSpaceManager);


            foreach (XmlNode childNode in nodeList)
            {
                ReceiverPoint receiverPoint = new ReceiverPoint();
                receiverPoint.CloseDate = childNode.SelectSingleNode("ns:CloseDate", nameSpaceManager).InnerText;
                receiverPoint.CreateDate = childNode.SelectSingleNode("ns:CreateDate", nameSpaceManager).InnerText;
                receiverPoint.CreateWho = childNode.SelectSingleNode("ns:CreateWho", nameSpaceManager).InnerText;
                receiverPoint.Easting = childNode.SelectSingleNode("ns:Easting", nameSpaceManager).InnerText;
                receiverPoint.Elevation = childNode.SelectSingleNode("ns:Elevation", nameSpaceManager).InnerText;
                receiverPoint.IsDeployed = childNode.SelectSingleNode("ns:IsDeployed", nameSpaceManager).InnerText;
                receiverPoint.IsManual = childNode.SelectSingleNode("ns:IsManual", nameSpaceManager).InnerText;
                receiverPoint.LastModifyDate = childNode.SelectSingleNode("ns:LastModifyDate", nameSpaceManager).InnerText;
                receiverPoint.Latitude = childNode.SelectSingleNode("ns:LatitudeWGS84", nameSpaceManager).InnerText;
                receiverPoint.Line = childNode.SelectSingleNode("ns:Line", nameSpaceManager).InnerText;
                receiverPoint.Longitude = childNode.SelectSingleNode("ns:LongitudeWGS84", nameSpaceManager).InnerText;
                receiverPoint.ReceiverType = childNode.SelectSingleNode("ns:ReceiverType", nameSpaceManager).InnerText;
                receiverPoint.Station = childNode.SelectSingleNode("ns:Station", nameSpaceManager).InnerText;




                //Get all the values stored in the receiver point object
                string station = receiverPoint.Station;
                string line = receiverPoint.Line;
                string elevation = receiverPoint.Elevation;
                string latitude = receiverPoint.Latitude;
                string longitude = receiverPoint.Longitude;
                string isDeployed = receiverPoint.IsDeployed;
                string easting = receiverPoint.Easting;
                string receiverType = receiverPoint.ReceiverType;
                string closeDate = receiverPoint.CloseDate;
                string createDate = receiverPoint.CreateDate;
                string createWho = receiverPoint.CreateWho;
                string lastModifyDate = receiverPoint.LastModifyDate;


                Console.WriteLine("String lat : " + latitude);

                Console.WriteLine("String lon : " + longitude);

                Console.WriteLine("String create date : " + createDate);

                Console.WriteLine("String create who : " + createWho);

                //Save the data to the db
                //saveDataToDatabase(station, line, elevation, latitude, longitude, isDeployed, easting, receiverType, closeDate, createDate, createWho, lastModifyDate);

                receiverList.Add(receiverPoint);
            }


            return receiverList;
        }

Answer 2

在foreach循環內移動receiverList.Add（receiverPoint）。
