VB.Net Xml反序列化为一类 [英] VB.Net Xml Deserialization into a Class
问题描述
尝试将一些XML反序列化为我创建的类时遇到一个问题。
I have a bit of an issue trying to deserialize some XML into a class that I have created.
我得到的错误是:
There is an error in XML document (1, 2).

这是我创建的类,在这一点上没有什么幻想,我只是尝试使其正常工作:
Here is the class I created, it's nothing fancy at this point, I'm simply trying to get it to work:
Imports System.Xml.Serialization
<Serializable, XmlRoot("Document")> _
Public Class Document
<XmlElement("Type")> _
Public Property Type As String
<XmlElement("FileName")> _
Public Property FileName As String
End Class
这是XML从我正在使用的文件中获取:
And here is the XML from the file I am using:
<ArrayOfDocuments>
<Document>
<Type>Debit/Credit note</Type>
<FileName>dbE12901_acc1.doc</FileName>
</Document>
<Document>
<Type>Generic</Type>
<FileName>a3_lmbc_categories.xls</FileName>
</Document>
</ArrayOfDocuments>
最后,这是我使用的代码:
Finally, here is the code I am using:
Dim foundDocuments As New List(Of Document)
Dim xmldoc As New XmlDocument
xmldoc.Load(InterfaceFilePath)
Dim allText As String = xmldoc.InnerXml
Using currentStringReader As New StringReader(allText)
Dim xml as New XmlSerializer(GetType(List(Of Document)))
foundDocuments = TryCast(xml.Deserialize(currentStringReader), List(Of Document))
End Using
我终生不能对我来说,弄清楚为什么它不会反序列化。我的应用程序中还有其他不同类的实例,我已经检查过了,它们的结构方式是相同的,所以我不明白为什么它不起作用。
I cannot, for the life of me, figure out why it will not deserialize. I have other instances of different classes in my app and I have checked and the way they are structured is the same, so I do not understand why it will not work.
我需要另一只眼睛来检查我的工作,有没有人建议?
I need another pair of eyes just to check what I have done, does anyone have any suggestions?
推荐答案
向Chris Dunaway喊叫谁在上面的评论中为我解决了这个问题。
Shout out to Chris Dunaway who solved it for me in one of the comments above.
一个简单的更改ArrayOfDocuments => ArrayOfDocument
Was a simple case of changing ArrayOfDocuments => ArrayOfDocument
那之后效果很好
