对XmlAttribute而不是XmlElement进行反序列化处理

Question

我正在尝试对xml文档进行反序列化。我已经创建了一个类，该类包含用于存储值的自定义对象，但由于某些原因，它不会对XmlElement的任何内容进行反序列化。

Main：

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();
}
}   
}

运输类别：

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; }
}

}

和xml对接：

<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>

但当我运行代码时，MessageDetails和寄售结构不知何故为null。结果

我错过了什么？

这个反序列化对我来说非常好，但你可能有一个不使用Visual Studio为你生成类的原因：

样本代码：

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
