如何将xml传递给C#中的View？

Question

它从请求中以字符串形式提供 xml。反序列化后，我无法使用 get 方法从 xml 中获取任何值。同样在Vehicle.cshtml 中，我试图获得DeviceId 的值。它仅将字符串名称 DeviceId 获取到 html 标签。得不到价值。我的方式有什么问题吗？如何从视图中获取这些 xml 值？

DataSet.cs

using System;
using System.Xml.Serialization;

namespace ShippingProject.Models
{
  //  [System.Xml.Serialization.XmlRootAttribute("DataSet", Namespace = "http://www.arvento.com/", IsNullable = false)]

    [XmlRoot("DataSet")]
    public class DataSet
    {
        [XmlElement("Device_x0020_No")]
        public string DeviceId { get; set; }
        [XmlElement("Latitude")]
        public double Latitude { get; set; }
        [XmlElement("Longitude")]
        public double Longitude { get; set; }
        [XmlElement("Address")]
        public string Address { get; set; }
    }
} 

HomeController.cs

 public IActionResult Vehicle()
        {
            // Create web client.
            WebClient client = new WebClient();

            // Download string.
            string value = client.DownloadString("http://ws.arvento.com//v1/report.asmx/GetVehicleStatus?Username=username&PIN1=password&PIN2=password&Language=string");

            // Write values.
            Console.WriteLine("--- WebClient result ---");
            Console.WriteLine(value.Length);
            Console.WriteLine(value);
            XmlSerializer serializer = new XmlSerializer(typeof(List<DataSet>), new XmlRootAttribute("DataSet"));
            //  DataSet result;
            var ms = new MemoryStream(Encoding.UTF8.GetBytes(value));
            var rdr = new XmlTextReader(ms) { Namespaces = false };
          //  StringReader rdr = new StringReader(value);
          /*  using (TextReader rdr = new StringReader(value))
                  {
                      result = (DataSet)serializer.Deserialize(reader);
                  } 
               StreamReader rdr = new StreamReader(value);*/
            List<DataSet> datasetList = (List<DataSet>)serializer.Deserialize(rdr);
            Console.WriteLine("--- Deserialize result ---");
            Console.WriteLine(datasetList);
            datasetList.ForEach(dl => {
                Console.WriteLine(dl.DeviceId);
                Console.WriteLine(dl.Latitude);
                Console.WriteLine(dl.Longitude);
                Console.WriteLine(dl.Address);
                Console.WriteLine();
            });
            return View();
        }

Vehicle.cshtml
@model DataSet
@Html.LabelFor(model => model.DeviceId)

这是我的 xml 文件：

尝试以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace ConsoleApplication8
{
    class Program
    {
        const string FILENAME = @"C:\temp\test.xml";
        static void Main(string[] args)
        {
            string xml = File.ReadAllText(FILENAME);
            StringReader sReader = new StringReader(xml);
            XmlReader reader = XmlReader.Create(sReader);
            XmlSerializer serializer = new XmlSerializer(typeof(DataSet));
            ConsoleApplication8.DataSet dataset = (ConsoleApplication8.DataSet)serializer.Deserialize(reader);
 
        }
    }
    public class Diffgram
    {
        [XmlArray(ElementName = "tblVehicleStatus", Namespace = "")]
        [XmlArrayItem(ElementName = "dtVehicleStatus", Namespace = "")]
        public List<DtVehicleStatus> DtVehicleStatus { get; set; } 
    }
    public class DtVehicleStatus
    {
            [XmlElement("Device No")]
            public string DeviceId { get; set; }
            [XmlElement("Latitude")]
            public double Latitude { get; set; }
            [XmlElement("Longitude")]
            public double Longitude { get; set; }
            [XmlElement("Address")]
            public string Address { get; set; }
    }
    [XmlRoot(ElementName = "DataSet", Namespace = "http://www.arvento.com/")]
    public class DataSet
    {
        [XmlElement(ElementName = "diffgram", Namespace = "urn:schemas-microsoft-com:xml-diffgram-v1")]
        public Diffgram Diffgram { get; set; }
    }
 

}
