反序列化处理 XmlAttribute 但不是 XmlElement

Question

我正在尝试反序列化一个 xml 文档。我创建了包含自定义对象以存储值的类，但由于某种原因，它不会反序列化任何用于 XmlElement 的内容。

主要：

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

namespace Bring_Uppgift
{
    class Program
    {
        static void Main(string[] args)
        {
            Transport T = new Transport();

            String filepath = @"C:***\Bing Uppgift";
            XmlSerializer serializer = new XmlSerializer(typeof(Transport));
            //StringReader reader = new StringReader(filepath + "\\test1.xml");
            //FileStream file = new FileStream(filepath + "\\test1.xml", FileMode.Open, FileAccess.Read);
            //StreamReader reader = new StreamReader(filepath + "\\test1.xml");
            using (StreamReader reader = new StreamReader(filepath + "\\test1.xml"))
            {
                T = (Transport)serializer.Deserialize(reader);
            }
            Console.ReadLine();
        }
    }   
}

运输类：

using System;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Serialization;

namespace Bring_Uppgift
{
    [Serializable]
    [XmlRoot(ElementName = "Transport", Namespace = "http://bring.com/TransportV13R0i")]
    public class Transport
    {
        [XmlElement(ElementName = "MessageDetails")]
        public MessageDetails MessageDetails { get; set; }

        [XmlElement(ElementName = "ConsignmentStructure")]
        public ConsignmentStructure ConsignmentStructure { get; set; }

        [XmlAttribute(AttributeName = "collaboration")]
        public string Collaboration { get; set; }

        [XmlAttribute(AttributeName = "messageFunction")]
        public string MessageFunction { get; set; }

        [XmlAttribute(AttributeName = "testIndicator")]
        public string TestIndicator { get; set; }

        [XmlAttribute(AttributeName = "messageId")]
        public string MessageId { get; set; }

        [XmlAttribute(AttributeName = "ns1", Namespace = "http://www.w3.org/2000/xmlns/")]
        public string Ns1 { get; set; }
    }
    
}

还有 xml 码头：

<ns1:Transport collaboration="Instruction" messageFunction="Instruction" testIndicator="NO" messageId="00376516406000" xmlns:ns1="http://bring.com/TransportV13R0i">
<MessageDetails>
    <MessageSender partyId="953675080" idType="30">
      <Contact contactFunction="">
        <ContactName>Bring Test</ContactName>
        <ComDetails comType="Phone">1234567</ComDetails>
      </Contact>
      <OriginatingSystem>
        <SystemId>BRINGMB</SystemId>
      </OriginatingSystem>
    </MessageSender>    
  </MessageDetails>
  <ConsignmentStructure structureType="Single">
  <ConsignmentSet updateIndicator="Original">
      <Consignment consignmentId="70712345678901234" idType="730">
        <ControlTotals>
          <NumberOfPackages>2</NumberOfPackages>
          <GrossWeight unitCode="KGM">70</GrossWeight>
        </ControlTotals>
        <Reference referenceType="CMR">
          <ReferenceNo>70713245679801234</ReferenceNo>
        </Reference>
        <Reference referenceType="CU">
          <ReferenceNo>41234</ReferenceNo>
        </Reference>
        <Reference referenceType="ANT">
          <ReferenceNo>4123456</ReferenceNo>
        </Reference>
        <Reference referenceType="DM">
          <ReferenceNo>70712345678901234</ReferenceNo>
        </Reference>
      </Consignment>
    </ConsignmentSet>
    </ConsignmentStructure>
</ns1:Transport>

但是当我运行代码时，MessageDetails 和 ConsignmentStructure 不知何故为空。 The result

我错过了什么？

这对我来说完全可以反序列化，但您可能有理由不使用 Visual Studio 为您生成类：

示例代码：

var transport =  (Transport)xmlSerializer.Deserialize(new StringReader(xml));

 Console.WriteLine($"MessageDetails.MessageSender.OriginatingSystem.SystemId: {transport.MessageDetails.MessageSender.OriginatingSystem.SystemId}");
 Console.WriteLine($"MessageDetails.MessageSender.Contact.ContactName: {transport.MessageDetails.MessageSender.Contact.ContactName}");
 Console.WriteLine($"MessageDetails.MessageSender.partyId: {transport.MessageDetails.MessageSender.partyId}");

打印：

MessageDetails.MessageSender.OriginatingSystem.SystemId: BRINGMB
MessageDetails.MessageSender.Contact.ContactName: Bring Test
MessageDetails.MessageSender.partyId: 953675080
