c# xmlelement在派生类中更改顺序

我正在尝试序列化XML。我想在派生类中添加一个新属性，并将其放在基类的其他属性之间。

在这个示例中，我想把'SpecialInterests'放在基类的'Name'和'Age'之间。

XML

<!-- Output -->
    <PersonenListe xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
      <PersonenArray>
        <PersonObjekt>
          <Name>Max Man</Name>
          <Age>33</Age>
        </PersonObjekt>
        <PersonObjekt xsi:type="SpecialPerson">
          <Name>Albert Einstein</Name>
          <Age>36</Age>
          <SpecialInterests>Physics</SpecialInterests>
        </PersonObjekt>
      </PersonenArray>
    </PersonenListe>
<!-- Desire -->
    <PersonenListe>
      <PersonenArray>
        <PersonObjekt>
          <Name>Max Man</Name>
          <Age>33</Age>
        </PersonObjekt>
        <PersonObjekt xsi:type="SpecialPerson">
          <Name>Albert Einstein</Name>
          <SpecialInterests>Physics</SpecialInterests>
          <Age>36</Age>
        </PersonObjekt>
      </PersonenArray>
    </PersonenListe>

c# - Main(创建实例和序列化)

static void Main(string[] args)
    {
        PersonalList personen = new PersonalList();
        Person normPerson = new Person { Name = "Max Man", Age = 33 };
        SpecialPerson specPerson = new SpecialPerson 
        { Name = "Albert Einstein", Interests = "Physics", Age = 36 };
        personen.AddPerson(normPerson);
        personen.AddPerson(specPerson);
        Type[] personTypes = new Type[personen.Persons.Count];
        for (int i = 0; i < personen.Persons.Count; i++)
        {
            personTypes[i] = personen.Persons[i].GetType();
        }
        XmlSerializer serializer = new XmlSerializer(typeof(PersonalList), personTypes);
        FileStream fs = new FileStream("Personenliste.xml", FileMode.Create);
        serializer.Serialize(fs, personen);
        fs.Close();
        personen = null;
        // Deserialize 
        fs = new FileStream("Personenliste.xml", FileMode.Open);
        personen = (PersonalList)serializer.Deserialize(fs);
        serializer.Serialize(Console.Out, personen);
        Console.ReadLine();
    }
