將REST XML響應反序列化到對象 - 在有效XML上失敗

Question

我嘗試反序列化從REST Web服務器獲得的xml文檔對象。這是我從服務器得到確切回覆（有效的XML）：

<?xml version="1.0" encoding="utf-8"?> 
<ads:body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xmlns:ads="http://www.ads.org/AnimalDataSchema"> 
    <ads:header> 
     <ads:createdBy>Polaris</ads:createdBy> 
     <ads:dateTimeCreated>2016-01-20T10:22:23Z</ads:dateTimeCreated> 
    </ads:header> 
    <ads:animals count="2"> 
     <ads:animal> 
      <ads:internalIdentifier>1</ads:internalIdentifier> 
      <ads:eid>982 000360237659</ads:eid> 
      <ads:dob>2012-05-01</ads:dob> 
      <ads:breed>Angus</ads:breed> 
      <ads:customLifeTimeData> 
       <ads:name>VID</ads:name> 
       <ads:value>TTDEMO1</ads:value> 
      </ads:customLifeTimeData> 
     </ads:animal> 
     <ads:animal> 
      <ads:internalIdentifier>2</ads:internalIdentifier> 
      <ads:eid>982 000359951630</ads:eid> 
      <ads:dob>2012-05-02</ads:dob> 
      <ads:breed>Angus</ads:breed> 
      <ads:customLifeTimeData> 
       <ads:name>VID</ads:name> 
       <ads:value>TTDEMO2</ads:value> 
      </ads:customLifeTimeData> 
     </ads:animal> 
    </ads:animals> 
</ads:body> 

我用deserialise對象類將是這樣：

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

namespace ***.IOT.Schemas 
{ 
    public class ADI_animal 
    { 
     [XmlRoot(ElementName = "header", Namespace = "http://www.ads.org/AnimalDataSchema")] 
     public class Header 
     { 
      [XmlElement(ElementName = "createdBy", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string CreatedBy { get; set; } 
      [XmlElement(ElementName = "dateTimeCreated", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string DateTimeCreated { get; set; } 
     } 

     [XmlRoot(ElementName = "customLifeTimeData", Namespace = "http://www.ads.org/AnimalDataSchema")] 
     public class CustomLifeTimeData 
     { 
      [XmlElement(ElementName = "name", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Name { get; set; } 
      [XmlElement(ElementName = "value", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Value { get; set; } 
     } 

     [XmlRoot(ElementName = "animal", Namespace = "http://www.ads.org/AnimalDataSchema")] 
     public class Animal 
     { 
      [XmlElement(ElementName = "internalIdentifier", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string InternalIdentifier { get; set; } 
      [XmlElement(ElementName = "eid", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Eid { get; set; } 
      [XmlElement(ElementName = "dob", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Dob { get; set; } 
      [XmlElement(ElementName = "breed", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Breed { get; set; } 
      [XmlElement(ElementName = "customLifeTimeData", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public CustomLifeTimeData CustomLifeTimeData { get; set; } 
     } 

     [XmlRoot(ElementName = "animals", Namespace = "http://www.ads.org/AnimalDataSchema")] 
     public class Animals 
     { 
      [XmlElement(ElementName = "animal", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public List<Animal> Animal { get; set; } 
      [XmlAttribute(AttributeName = "count")] 
      public string Count { get; set; } 
     } 

     [XmlRoot(ElementName = "body", Namespace = "http://www.ads.org/AnimalDataSchema")] 

     public class Body 
     { 
      [XmlElement(ElementName = "header", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public Header Header { get; set; } 
      [XmlElement(ElementName = "animals", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public Animals Animals { get; set; } 
      [XmlAttribute(AttributeName = "xsi", Namespace = "http://www.w3.org/2001/XMLSchema-instance")] 
      public string Xsi { get; set; } 
      [XmlAttribute(AttributeName = "ads", Namespace = "http://www.ads.org/AnimalDataSchema")] 
      public string Ads { get; set; } 
     } 

    } 
} 

調試輸出是：

Exception thrown: 'System.InvalidOperationException' in Microsoft.GeneratedCode 
The thread 0xdfc has exited with code 0 (0x0). 
The thread 0xb34 has exited with code 0 (0x0). 
Exception thrown: 'System.Reflection.TargetInvocationException' in mscorlib.ni.dll 
Exception thrown: 'System.InvalidOperationException' in System.Xml.XmlSerializer.dll 
exception caught: There is an error in XML document (1, 40). 

我運行的代碼：

static public void ProcessResponse(XmlDocument queryResponse) 
    { 
      String queryRootString; 
      ADI_animal adsObject = new ADI_animal(); 
      using (var stringWriter = new StringWriter()) 
      using (var xmlTextWriter = XmlWriter.Create(stringWriter)) 
      { 
       XmlDocument queryRoot = queryResponse; 
       queryRoot.WriteTo(xmlTextWriter); 
       xmlTextWriter.Flush(); 
       queryRootString = stringWriter.GetStringBuilder().ToString(); 
      } 
      try 
      { 
       XmlSerializer result = new XmlSerializer(typeof(ADI_animal)); 

       adsObject = (ADI_animal)result.Deserialize(new StringReader(queryRootString)); 
      } 
      catch (Exception ex) 
      { 
       Debug.WriteLine("exception caught: " + ex.Message); 
      } 
} 

非常多的告訴我，XML文檔在命名空間中存在問題。但我找不到這個錯誤。也許有人能給我一個正確的方向推動？

您試圖反序列化XML，看起來像ADI_animal.Body的串行器配置爲期望ADI_animal作爲頂級對象。

不清楚自己在找什麼，但desirializing該XML爲ADI_animal.Body實例應該很好地工作：

XmlSerializer result = new XmlSerializer(typeof(ADI_animal.Body)); 
var body = (ADI_animal.Body)result.Deserialize(new StringReader(queryRootString));

調試注意：爲簡化反序列化嘗試的調查序列化對象先來看看什麼形狀預計XML：

XmlSerializer result2 = new XmlSerializer(typeof(ADI_animal)); 
var w = new StringWriter(); 
result2.Serialize(w, new ADI_animal()); 
Console.WriteLine(w.ToString()); 

XmlSerializer result2 = new XmlSerializer(typeof(ADI_animal)); 
var w = new StringWriter(); 
result2.Serialize(w, new ADI_animal()); 
Console.WriteLine(w.ToString());
