XML Deserialzing causes exception

[Simon Jefferies]

Hello,

I'm trying to deserialize a document created with the following pieces of
code.

I get an exception "Additional information: There is an error in XML
document (2, 2).", why does this happen?

Serializing code:

Dim fs As New FileStream(Filename, FileMode.Create, FileAccess.Write)
Dim SoundTableItem As SoundTableItem = Nothing
For Each SoundTableItem In SoundItems

Dim XmlEntry As New
Xml.Serialization.XmlSerializer(GetType(SoundTableItem))
XmlEntry.Serialize(fs, SoundTableItem)

Next

fs.Close()

Deserializing code:

Dim fs As New FileStream(Filename, FileMode.Open, FileAccess.Read)
Dim tr As New Xml.XmlTextReader(fs)
Dim XmlEntry As New Xml.Serialization.XmlSerializer(GetType(SoundTableItem))
While Not tr.EOF()
Dim SoundEntry As SoundTableItem = Nothing
SoundEntry = XmlEntry.Deserialize(tr)
SoundItems.Add(SoundEntry)
End While

Hi Simon.

I made an other serialize routine using the stringwriter, you can try it.
It is changed the code in this message so there can be typos.

Dim Serializer As New
Xml.Serialization.XmlSerializer(GetType(BelgenCollection))
Dim sw As New System.IO.StringWriter
Serializer.Serialize(sw, Belgen)
dim mystring = sw.ToString

Dim Deserializer As New Xml.Serialization.XmlSerializer _
(GetType(BelgenCollection))
Dim sr As New System.IO.StringReader(Charles)
Dim reader As New System.Xml.XmlTextReader(sr)
Dim Vlamingen As BelgenCollection
Vlamingen = CType(Deserializer.Deserialize(reader), _
BelgenCollection)

It has to be a proper object.

Hi Simon,

First of all, I would like to confirm my understanding of your issue.
From your description, I understand that you wants to serialized an array
of objects into xml.
Have I fully understood you? If there is anything I misunderstood, please
feel free to let me know.

In addition to to Cor's suggestion, I think you may try to take a look at
the link below.

If you still have any concern on this issue, please feel free to let me
know.

Thanks for your link, your code examples came in handy and I have managed to
get it to work

Are there any books that you would recommend that help in this area?

Hi Simon,

Thank you for your update.
I think the book below will be a good start about XML Programming.
Applied XML Programming for Microsoft .NET
