如何序列化XML C＃中的内置对象？

Question

我有一个复杂的类相互参照的系统。 我使用XML序列化保存我的DataGrid。

类：

[Serializable]
public class CompJobArray
{
    [XmlElement("Room")]
    public ObservableCollection<Room> RoomList = new ObservableCollection<Room>();
    public CompJobArray() { }
}

public class Room
{
    public string roomName { get; set; }
    public double floorSquare { get; set; }
    public double ceilingSquare { get; set; }
    public double wallsSquare { get; set; }
    public double floorPerimeter { get; set; }
    public double ceilingPerimeter { get; set; }
    public ObservableCollection<CompJob> CompJobsCollection{ get; set; }

    public Room() { }

    public Room(string Name, double fS,double cS,double wS,double fP,double cP)
    {
        roomName = Name;
        floorSquare = fS;
        ceilingSquare = cS;
        wallsSquare = wS;
        floorPerimeter = fP;
        ceilingPerimeter = cP;
        CompJobsCollection = new ObservableCollection<CompJob>();
    }

}

[Serializable]
public class CompJob
{
    public job CompJobjob { get; set; }
    public float Count { get; set; }
    public float TotalPrice { get; set; }

   public CompJob() { }

    public CompJob(job tempJob, float count)
    {
        CompJobjob = tempJob;
        Count = count;
        TotalPrice = tempJob.price*count;
    }
}

[Serializable]
public class job
{

    public int id { get; set; }
    public string name { get; set; }
    public float price { get; set; }
    public string measure { get; set; }

    public job() { }

    public job(int t1, string t2, float t3, string t4)
    {
        id = t1;
        name = t2;
        price = t3;
        measure = t4;
    }
}

所有类都按链工作：CompJobArray-> Room-> CompJob-> Job。

Furhter，XAML和序列化：

private void SaveMenuItem_OnClick(object sender, RoutedEventArgs e)
    {
        using (StreamWriter swr = new StreamWriter(xmlFilePath))
        {
            CompJobArray tempJobArray = new CompJobArray();
            tempJobArray.RoomList = RoomList;

            deserializerCJA.Serialize(swr, tempJobArray);
        }
    }

<DataGrid  Grid.Row="2" ItemsSource="{Binding Path=CompJobsCollection}"  CanUserAddRows="True" AutoGenerateColumns="False">
      <DataGrid.Columns>
           <DataGridTextColumn Header="Наименование элемента" Binding="{ Binding Path=CompJobjob.name, Mode=TwoWay}"  />
           <DataGridTextColumn Header="Количество" Binding="{Binding Path=Count ,Mode=TwoWay}" />
           <DataGridTextColumn Header="Сумма" Binding="{Binding Path=TotalPrice,Mode=TwoWay}" />
      </DataGrid.Columns>
</DataGrid>

最后-作业未保存：

<CompJobsCollection>
  <CompJob>
    <Count>12</Count>
    <TotalPrice>150</TotalPrice>
  </CompJob>
</CompJobsCollection>

详细说明：我将Room类反序列化为ObservableCollection，然后分配Obs。 收集到DataGrid。 当我编辑datagrid并保存它时-一切都很好，除了保存CompJob类中内置的作业类，Room类中内置的作业类为Obs。 采集。

在我的datagrid中编辑作业字段后，该怎么办，保存后，我会看到xml中的更改吗？
