[Mono-dev] Error Deserializing with XmlSerializer feeding off of XLinq XML Reader

[Dan Shechter]

Hi all,

I've found an error with XLinq (?) running on Ubuntu 8.04 amd64:

 

When trying to use an XMLSerializer to de-serialize data that was
read/manipulated with XLinq,

The deserializer fails with the following exception:

  at System.Xml.XmlReader.get_Name () [0x00000]

  at
System.Xml.Serialization.XmlSerializationReaderInterpreter.ReadAttributeMemb
ers (System.Xml.Serialization.ClassMap map, System.Object ob, Boolean
isValueList) [0x00000]

  at System.Xml.Serialization.XmlSerializationReaderInterpreter.ReadMembers

  at System.Xml.Serialization.XmlSerializer.Deserialize
(System.Xml.Serialization.XmlSerializationReader reader) [0x00000]

 

The deserializer was called like this:

var xr = doc.CreateReader();

var me = _serializer.Deserialize(xr) as ChannelConfiguration;

 

The same code compiles and runs cleanly with MS .NET.

The same deserializer has no problem reading XmlDocuments that are fed to it
with:

var xr = new XmlNodeReader(doc);

var me = _serializer.Deserialize(xr) as ChannelConfiguration;

 

I will file an official bug report at a later time.

 

If anyone has any idea of how to circumvent this (while still using XLinq /
XDocument as the source for deserialization) I will be most greatful.
