Lista de serialización <T> que contiene la lista <T>

Question

Estoy tratando de serializar una lista que contiene tipos que no son del sistema.

A continuación se muestra mi código de serialización que funciona bien en el nivel superior. y devuelve un XmlDocument válido, pero no parece contener nada en una lista interna.

He mirado alrededor de la red, y alrededor de SO, ¡pero no puedo encontrar nada!

Cualquier ayuda muy apreciada.

Código:

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; 
} 

código utilizado para la prueba: Salida

[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; } 
}

Answer 1

inner propiedad debe tener colocador con el fin de ser serializable.

Si lo cambia a

public InnerListTestClass inner { get; set; } 

Se serializado, como se espera que lo haga.

<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>
