Xml Deserializer 不适用于我的 gpx 文件

Question

我正在尝试将一个 gpx 文件反序列化为一个类，但我遇到了麻烦。我尝试将 gpx 文件文本输入到 Xml2CSharp 并以这种方式生成一个类，但我不确定它是否正确（http://xmltocsharp.azurewebsites.net/）。当我使用调试器时，gpx 为空。有人可以给我一些关于我做错了什么的见解吗？谢谢。

Gpx 文本：

<gpx xmlns="http://www.topografix.com/GPX/1/1" version="1.0">
   <trk>
      <trkseg>
         <start lat="37.48996833333333" lon="-122.20991333333335">
            <ele>127.1</ele>
            <time>2017-11-07T02:53:07Z</time>
         </start>
         <trkpt lat="37.48996833333333" lon="-122.20991333333335">
            <ele>127.1</ele>
            <time>2017-11-07T02:53:07Z</time>
         </trkpt>
         <trkpt lat="37.48996833333333" lon="-122.20991333333335">
            <ele>127.1</ele>
            <time>2017-11-07T02:53:07Z</time>
         </trkpt>
      </trkseg>
   </trk>
</gpx>

当前班级：

public class XmlSerializeGpx
{
    public Gpx gpx { get; set; }

    public class Start
    {
        public string Ele { get; set; }
        public string Time { get; set; }
        public string Lat { get; set; }
        public string Lon { get; set; }
    }

    public class Trkpt
    {
        public string Ele { get; set; }
        public string Time { get; set; }
        public string Lat { get; set; }
        public string Lon { get; set; }
    }

    public class Trkseg
    {
        public Start Start { get; set; }
        public List<Trkpt> Trkpt { get; set; }
    }

    public class Trk
    {
        public Trkseg Trkseg { get; set; }
    }

    public class Gpx
    {
        public Trk Trk { get; set; }
        public string Xmlns { get; set; }
        public string Version { get; set; }
    }
}

这是我的反序列化器：

XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "gpx";
xRoot.Namespace = gpxNs.NamespaceName;
xRoot.IsNullable = true;

XmlSerializer xmlSerializer = new XmlSerializer(typeof(XmlSerializeGpx),xRoot);
FileStream fs = new FileStream(file.Path, FileMode.Open);
XmlReader reader = XmlReader.Create(fs);

XmlSerializeGpx gpxObj;

gpxObj = (XmlSerializeGpx)xmlSerializer.Deserialize(reader);

fs.Close();

您需要正确输入大小写字母。请参阅下面的测试代码

using System.Xml;
using System.Xml.Serialization;
using System.IO;


namespace ConsoleApplication1

            XmlSerializer xmlSerializer = new XmlSerializer(typeof(XmlSerializeGpx.Gpx), "http://www.topografix.com/GPX/1/1");

            FileStream fs = new FileStream(FILENAME, FileMode.Open);
            XmlReader reader = XmlReader.Create(fs);

            XmlSerializeGpx.Gpx gpxObj = (XmlSerializeGpx.Gpx)xmlSerializer.Deserialize(reader);

        }
