vb.net - VB.NET 反序列化/我应该使用哪种模式？

问题描述

我想以对象形式映射给定的 XML。XML包括例如文件路径之类的值。典型路径由文件夹路径的 xml 属性和文件名组成。该模式应该让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我的代码的可概览性（或者我应该使用其他包装器吗？）。有什么反对这种方法的吗？有没有更好的方法？

反序列化时，总是返回以下错误：

“InvalidOperationException：http://example.net/V3.0/Schema'> 不是预期的。”

有没有人可以解决如何使用其他方法扩展继承？

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

            Me.katalogversionField = 1
        End Sub


        '''<remarks/>
        <System.Xml.Serialization.XmlAttributeAttribute()>
        Public Property verfahren() As String

        Public Property verfahrensversion() As String
            Get
                Return Me.verfahrensversionField
            End Get
            Set
                Me.verfahrensversionField = Value
            End Set
        End Property

         System.ComponentModel.DefaultValueAttribute(1)>

            Set

        End Property
    End Class
End Namespace
