Question

我想以对象形式映射给定的XML。 XML包括例如值就像文件路径一样。典型的路径由用于文件夹路径的xml属性和文件名组成。该模式应该使我有机会随时加载和保存对象。我不想总是手动将文件路径放在一起或将它们分开。（我不想更改原始的序列化对象（例如“ katalog”，“ kovkatalog”），因为它是自动生成的。）

我认为继承可以解决我的问题并提高代码的可概述性（或者应该使用其他包装器？）。有什么不对的方法吗？有没有更好的方法？

反序列化时，始终返回以下错误：

“ InvalidOperationException：不需要http://example.net/V3.0/Schema'>。”

有人对我如何使用其他方法扩展继承有解决方案吗？

VB.NET代码：

Namespace abc
    Public Class Main
        Public Sub New()
            Dim des As New unifa_katalog
            des = Deserialisieren(Of unifa_katalog)("<PATH_TO_FILE>\katalog.xml")
        End Sub

        Private Function Deserialisieren(Of T)(strSpeicherOrt As String) As T
            Dim serializer As New XmlSerializer(GetType(T))
            Dim deserialized As T = Nothing
            Using file = System.IO.File.OpenRead(strSpeicherOrt)
                deserialized = DirectCast(serializer.Deserialize(file), T)
            End Using
            Return deserialized
        End Function
    End Class

    <XmlRoot("katalog", [Namespace]:="urn:kosxmlns")>
    Partial Public Class unifa_katalog
        Inherits katalog
        Public Sub furtherMethod()

        End Sub

    End Class

这实际上不是继承问题，而是名称空间问题。如果使用相同的名称空间，它将反序列化

<XmlRoot("katalog", [Namespace]:="http://example.net/V3.0/Schema")>
Partial Public Class unifa_katalog
    Inherits katalog
    Public Sub furtherMethod()
    End Sub
End Class

VB.NET反序列化/应该使用哪种模式？
