处理嵌套列表对象属性

Question

大家好，我正在设法找出有效的方法来处理这些嵌套的列表对象，在本例中，从XML反序列化。例如，这个模型结构

public class Car 
   public property wheels as List(Of Wheels)
   public property BearingType as String 
end class

public class Wheels
   public property bearings as List(Of Bearings)
end class

public class Bearings
   public property BearingType as String 
end class

假设我像这样反序列化了2个Car对象

Car 1 (
Wheel 1 (Bearing 1 (BearingType Alloy) , Bearing 2(BearingType Alloy)
Wheel 2 (Bearing 3 (BearingType Alloy) , Bearing 4(BearingType Alloy)
)

Car 2(
Wheel 1 (Bearing 1 (BearingType Metal) , Bearing 2(BearingType Metal)
Wheel 2 (Bearing 3 (BearingType Metal) , Bearing 4(BearingType Metal)
)

因为我确信一辆车只会有一种类型的BearingType，我如何将轴承类型分配给父级？这样我就可以通过Car.BearingType而不是Car.Wheels(0).Bearings(0).BearingType来访问它。

那么XML-结构是由其他人定义的吗？那么我就留着它，如果你是舒尔，它就只有一个，那么你就能解决这个既快又脏的问题：

Public Class Car
    Public Property wheels As List(Of Wheels)
    Public Property BearingType As String
        Get
            Return Me.wheels(0).bearings(0).BearingType()
        End Get
        Set(value As String)  
            For Each wheel In Me.wheels
                For Each bearing In wheel.bearings
                    bearing.BearingType = value
                Next
            Next
        End Set
    End Property
End Class

或者更好:实现IXmlSerializable。

否则，重新格式化xml文件并更新类。
