All the examples i've found using XmlSerializer work with one time
serialization / deserialization of objects... or one time
serialization / deserialization of collection of objects.
I need to be able to keep a file stream open, and just serialize
(IrcMessage) objects as they come into my server, then eventually have
some other thread deserialize the accumulated (IrcMessage) objects.
the problem is, every time i call:
StreamWriter messageWriter = new
StreamWriter(_logFileStream, Encoding.ASCII);
XmlSerializer writer = new
XmlSerializer(typeof(IrcMessage));
writer.Serialize(messageWriter, ircMessage2);
where:
[Serializable]
public class IrcMessage
{
int _channelId = -1;
public int ChannelId
{
get { return _channelId; }
set { _channelId = value; }
}
string _ircMessageText = null;
public string IrcMessageText
{
get { return _ircMessageText; }
set { _ircMessageText = value; }
}
}
it causes the following output:
<?xml version="1.0" encoding="us-ascii"?>
<IrcMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<ChannelId>1</ChannelId>
<IrcMessageText>103 Host my hostabc</
IrcMessageText>
</IrcMessage><?xml version="1.0" encoding="us-ascii"?>
<IrcMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<ChannelId>2</ChannelId>
<IrcMessageText>boohaha string</IrcMessageText>
</IrcMessage><?xml version="1.0" encoding="us-ascii"?>
<IrcMessage xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";>
<ChannelId>1</ChannelId>
<IrcMessageText>sasdjlfsdjfsdjsfdjkfsdjksdfjksdafjk;sd;jasdf</
IrcMessageText>
</IrcMessage>
one problem is i don't want the xml version info to keep being
rewritten...
when trying to deserialize:
StreamReader ircMessageReader = new
StreamReader(logFileStream);
XmlSerializer ircMessageParser = new
XmlSerializer(typeof(IrcMessage));
return
(IrcMessage)ircMessageParser.Deserialize(ircMessageReader);
i blow up with Unexpected XML declaration... trying to manually remove
the declaration from the files causes other errors. but this is only
1 issue i'm seeing.
i could accumulate the objects in a collection then do a onetime
serialization of a collection of IrcMessage objects, then deserialize
the collection in the same manner - but this IS NOT what i'm after.
I.e. i wish to serialize IrcMessage objects to file as they come
in... (as stated in 2nd paragraph)
any help would be most appreciated!
thanks, dave
