使用XMLSerializer访问内部属性

我试图通过使用XmlSerializer类序列化XML文件。Xml结构看起来像:

<?xml version="1.0"?>
<Datatable xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Assets>
    <A_elements>
      <A_el ID="1">
        <Fields>
          <Field Hint="First field">
             <Title> A_field </Title>
             <Value> 111 </Value>
          </Field>
          <Field Hint="Second field">
             <Title> B_field </Title>
             <Value> 222 </Value>
          </Field>
          .....
          .....
        </Fields>
      </A_el>
    </A_elements>
  </Assets>
</Datatable>

我怎么能访问字段值时，我指定[XmlElement(")]?

例如，我希望从这个xml中加载的c#对象可读为:LoadedObject.Assets.A_elements[0].A_field

，上面代码的输出应该是"111"

我正试着用这种方法解决这个问题:

[XmlRoot("Assets"), Serializable]
    public class Assets
    {
        [XmlElement("A_elements")]
        public Actors actors { get; set; }
    }
public class A_elements
{
    [XmlElement("A_elements")]
    public List<A_el> A_elList { get; set; }
}

public class A_el
{
    [XmlAttribute("ID")]
    public int id { get; set; }
    [------??????------]
    public string A_field { get; set; }
}

字段没有任何唯一标识符，并且在所有元素中都有许多字段。我将非常感谢任何帮助。

public class A_el
{
    [System.Xml.Serialization.XmlAttribute("ID")]
    public int id { get; set; }
    [System.Xml.Serialization.XmlArray(ElementName = "Fields")]
    [System.Xml.Serialization.XmlArrayItem("Field", typeof(Field))]
    public Field[] Fields { get; set; }
    private string[] _A_elements;
    private string[] A_elements
    {
        get
        {
            if(null == _A_elements)
            {
                _A_elements = (from field in Fields select field.Value).ToArray();
            }
            return _A_elements;
        }
    }
}
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class Field
{
    public string Title { get; set; }
    public string Value { get; set; }
    [System.Xml.Serialization.XmlAttributeAttribute()]
    public string Hint { get; set; }
}
