序列表列表<T>包含列表<T>

Question

我想序列化一个包含非系统类型的列表。

下面是我的序列化代码，它在顶层工作正常。并返回一个有效的XmlDocument，但似乎不包含内部列表中的任何内容。

我环顾过网 - 周围是 - 但似乎无法找到任何东西！

任何帮助非常感谢。

代码：用于测试

public static XmlDocument SerializeToXML<T>(List<T> list, string rootElement) 
{ 
    XmlAttributeOverrides overrides = new XmlAttributeOverrides(); 
    XmlAttributes attr = new XmlAttributes(); 
    attr.XmlRoot = new XmlRootAttribute(rootElement); 
    overrides.Add(typeof(List<T>), attr); 

    XmlDocument xmlDoc = new XmlDocument(); 
    XPathNavigator nav = xmlDoc.CreateNavigator(); 
    using (XmlWriter writer = nav.AppendChild()) 
    { 
     XmlSerializer ser = new XmlSerializer(typeof(List<T>), overrides); 

     ser.Serialize(writer, list); 
    } 
    return xmlDoc; 
} 

代码：

[TestFixture] 
public class BaseTesting 
{ 
    [Test] 
    public void test() 
    { 
     List<ListTestClass> list = new List<ListTestClass>(); 

     for (int i = 0; i < 20; i++) 
     { 
      list.Add(new ListTestClass() { intProp = 1, stringProp = "string1", dtProp = DateTime.Now }); 
     } 

     XmlDocument doc = Beyond.Base.Util.XMLUtils.SerializeToXML<ListTestClass>(list, "root"); 
    } 
} 

public class ListTestClass 
{ 
    public int intProp { get; set; } 

    public string stringProp { get; set; } 

    public DateTime dtProp { get; set; } 

    [XmlElement("Inner",typeof(InnerListTestClass))] 
    public InnerListTestClass inner { get { return new InnerListTestClass() { intProp = 1, stringProp = "string1", dtProp = DateTime.Now }; } } 
} 

public class InnerListTestClass 
{ 
    public int intProp { get; set; } 

    public string stringProp { get; set; } 

    public DateTime dtProp { get; set; } 
} 

XML输出：

Answer 1

inner属性必须有先导作用，以可序列化。

如果将其更改为

public InnerListTestClass inner { get; set; } 

将被序列化，因为你希望它。

<ListTestClass> 
<intProp>1</intProp> 
<stringProp>string1</stringProp> 
<dtProp>2011-06-07T01:57:07.1200742-07:00</dtProp> 
<Inner> 
    <intProp>1</intProp> 
    <stringProp>string1</stringProp> 
    <dtProp>2011-06-07T01:57:07.1210743-07:00</dtProp> 
</Inner> 
</ListTestClass>
