试图使用DataContractSerializer反序列化整数列表，收到意外的InvalidOperationException

Question

期望：从XML文件读取列表中的ints列表，名为itemPool;

结果：“出现InvalidOperationException：无法添加类型System.Collections.Generic.List`1 [System.Int32]已知类型的集合已经有一个注册类型的XML名称http://schemas.microsoft.com/2003/10/Serialization/Arrays:ArrayOfint。”

我要以下代码：

using System.Collections.Generic; 
using System.Runtime.Serialization; 

using Characters; 
using Items; 

[DataContract(Name ="Savefile", Namespace ="")] 
public class Savefile 
{ 
    [DataMember(Name ="Characters")] 
    public List<Character> characters = new List<Character>(); 

    [DataMember(Name = "ItemPool")] 
    public List<int> itemPool = new List<int>(); 

    public void Initialize() 
    { 
     foreach (Character c in characters) 
      c.Initialize(); 

     ItemPool.Load(itemPool.ToArray()); 
    } 
} 

并用以下方法另一个类：

public static void LoadFromSavefile() 
    { 
     DataContractSerializer serializer = new DataContractSerializer(typeof(Savefile)); 
     FileStream stream = new FileStream(Path.Combine(Application.dataPath, _savefilePath), FileMode.Open); 

     _currentSave = serializer.ReadObject(stream) as Savefile; 

     stream.Close(); 
    } 

而下面的XML的文件，类ABO已经读过。

<?xml version="1.0" encoding="utf-8"?> 
<Savefile xmlns:i="http://www.w3.org/2001/XMLSchema-instance"> 
    <Characters> 
    <Character> 
     <... not relevant clutter.../> 
    </Character> 
    </Characters> 
    <ItemPool> 
    <value>1</value> 
    </ItemPool> 
</Savefile>

使用DataContractSerializer编辑。

using System; 
using Microsoft.VisualStudio.TestTools.UnitTesting; 
using System.Runtime.Serialization; 
using System.Collections.Generic; 
using System.IO; 
using System.Xml; 
using System.Xml.Serialization; 

namespace UnitTestProject1 { 

    [DataContract(Name = "Savefile", Namespace = "")] 
    public class Savefile { 
     [DataMember(Name = "Characters", Order = 0)] 
     public Characters Characters { get; private set; } 

     [DataMember(Name = "ItemPool", Order = 1)] 
     public Items ItemPool { get; private set; } 

    } 

    [CollectionDataContract(Name = "Characters", ItemName = "Character", Namespace = "")] 
    public class Characters : List<Character> { 

    } 

    public class Character { 
     public string Weapon { get; set; } 
     internal void Initialize() { 
      throw new NotImplementedException(); 
     } 
    } 

    [CollectionDataContract(Name = "ItemPool", ItemName = "Item", Namespace = "")] 
    public class Items : List<int> { 
     public int value { get; set; } 
    } 

    [TestClass] 
    public class UnitTestSerialization { 
     [TestMethod] 
     public void TestMethod1() { 
      DataContractSerializer serializer = new DataContractSerializer(typeof(Savefile)); 
      FileStream stream = new FileStream("SaveFile2.xml", FileMode.Open); 
      XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(stream, new XmlDictionaryReaderQuotas()); 

      Savefile _currentSave = (Savefile)serializer.ReadObject(reader); 
      Assert.IsNotNull(_currentSave); 


      stream.Close(); 
     } 
    } 
} 

xml文件

<?xml version="1.0" encoding="utf-8"?> 
<Savefile> 
    <Characters> 
    <Character> 
     <Weapon>Axe</Weapon> 
    </Character> 
    <Character> 
     <Weapon>Mace</Weapon> 
    </Character> 
    <Character> 

    </Character> 
    </Characters> 
    <ItemPool> 
    <Item>1</Item> 
    <Item>2</Item> 
    </ItemPool> 
</Savefile>
