[英]VB.NET deserialization / Which pattern should i use?
I want to map a given XML in object form. 我想以对象形式映射给定的XML。 The XML includes eg values like a file path.
XML包含例如文件路径之类的值。 A typical path consists of an xml-attribute for the folder-path and a file-name.
典型的路径由用于文件夹路径的xml属性和文件名组成。 The pattern should give me the opportunity to load and save object at any time.
该模式应该使我有机会随时加载和保存对象。 I don't want to put the file path always manually together or separate them.
我不想总是手动将文件路径放在一起或将它们分开。 (I don't want to change the original serialized-object (like "katalog","kovkatalog",) because it is automatically generated.)
(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。)
I think inheritance could solve my problem and improve the overviewability of my code (or should I use an other wrapper?). 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?)。 Is something against the approach?
有什么不对的方法吗? Are there any better approaches?
有没有更好的方法?
When deserializing, the following error is always returned: 反序列化时,始终返回以下错误:
"InvalidOperationException: http://example.net/V3.0/Schema'> is not expected."
“不希望InvalidOperationException:http://example.net/V3.0/Schema'>。”
Does anyone have a solution for how I can extend inheritance with additional methods? 有谁对我如何使用其他方法扩展继承有解决方案?

It's not really an inheritance issue, rather a namespace issue. 这实际上不是继承问题,而是名称空间问题。 If you use the same namespace, it will deserialize
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
