XmlWriter with ConformanceLevel.Fragment

[Shimon Sim]

Hi
I keep getting error :

WriteStartDocument cannot be called on writers created with
ConformanceLevel.Fragment.

The code that I have is very simple.

SimpleClass c = new SimpleClass();

c.Name = "TestName";

XmlSerializer serializer = new XmlSerializer(typeof(SimpleClass));
MemoryStream stream =new MemoryStream();

XmlWriterSettings settings = new XmlWriterSettings();

settings.OmitXmlDeclaration = true;

settings.ConformanceLevel = ConformanceLevel.Fragment;
settings.Encoding = Encoding.ASCII;

XmlWriter writer = XmlWriter.Create(stream,settings);

serializer.Serialize(writer,c);

stream.Position = 0;

byte[] data=new byte[stream.Length];

stream.Read(data, 0, (int)stream.Length);
result = new string(Encoding.Default.GetChars(data));

I found in documentation that if there is DTD information that
WriteStartDocument will be called and with ConformanceLevel.Fragment writer
will throw an exception.

So where is DTD information? Can I remove it to make this work?

Thanks.

I guess the Serialize method of XmlSerializer calls the
WriteStartDocument method of XmlWriter. Why exactly do you set
ConformanceLevel.Fragment, what do you want to achieve with that setting?

I want to serialize class without header and without any default namespaces.
Header could be easily removed as you showed me earlier but to remove
namespaces that doesn't help. I did find one solution to go through
XmlDocument and extract a node from it.
But I wanted to do it directly using XmlWriter. I looked into custom
XmlWriters but didn't see any fast solution. So I thought that if I will use
Fragment it will not add any namespaces.
Thanks,
Shimon.
