如何在C＃中将层次结构类序列化和反序列化为xml？

Question

实际上我可以序列化，但我无法反序列化它。我需要有一个viewmodel的对象，所有的孩子都来自不稳定的输出，而且我也不确定我应该在哪里设置我的xml属性;模型或视图模型。

这是我的clss和viewmodel

public class Person
{
     public string Name { get; set; }       
     readonly List<Person> children = new List<Person>();
     public IList<Person> Children
     {
         get { return children; }
     }    
}

public class PersonViewModel : {

private ObservableCollection<PersonViewModel> children; 
private Person person;

public PersonViewModel()
{
    person = new Person();
}

public PersonViewModel(Person _person)
{
    person = _person;
    children = new ObservableCollection<PersonViewModel>(
            (from child in _person.Children
                select new PersonViewModel(child))
                .ToList<PersonViewModel>());
}

[XmlElement("Name", typeof(string))]
public string Name
{
    get
    {
        return person.Name;
    }

    set
    {
        person.Name = value;
        this.RaisePropertyChanged("Name");
    }
}

[XmlArray("Children", IsNullable = false), XmlArrayItem("Person"),]
public ObservableCollection<PersonViewModel> Children
{
    get
    {
        return children;
    }
}

}

这是我的代码已经生成的xml文件的内容。 但是当我想将它用于我的视图模型的对象类型时，子项将不会被现有数据初始化。

串行：

            XmlSerializer xs = new XmlSerializer(typeof(PersonViewModel), new XmlRootAttribute { ElementName = "OrgChart" });
        using (StreamWriter wr = new StreamWriter(System.AppDomain.CurrentDomain.BaseDirectory + "OrgChart.XML"))
        {
            xs.Serialize(wr, rootPerson);
        }

解串器：

                    XmlSerializer xs = new XmlSerializer(typeof(PersonViewModel), new XmlRootAttribute { ElementName = "OrgChart" });

                FileStream fs = new FileStream(filePath, FileMode.Open);
                XmlReader reader = XmlReader.Create(fs);

                rootPerson = SelectedItem = Profile = (PersonViewModel)xs.Deserialize(reader);
                reader.Close();
