DOCTYPE with Xml Serialization

I have a class that serialize using the XmlSerializer.
I am using several attributes for class members to control serialization
process.
One thing I cannot figure out how to do is how to add DOCTYPE attribute to
the file.
This XML file must use the doctype that refers to the DTD rather than an
XSD.

Could someone point out how to accomplish that using the attributes or by
some other means?

Thanks!

Hi Vlad,

Welcome to MSDN newsgroup.
From your description, when you use the .NET XmlSerizliation to serizliaze
some class instances out to xml stream, you want to also expose the DocType
for the whole xml document, yes?

As for the DOCTYPE, there hasn't buildin XmlSerlization Attributes for
specifying DOCTYPE. In fact, this is because the Xml Serialization is
Class/Element based rather than Document based. As for DOCTYPE, it is
specified for a certain Xml document. Currently I think we can use the
following means to inject the DOCTYPE in our serilization's output document:

When do the serizliation, we use an XmlTextWriter to delegate the
underlying StreamWriter we'll write out the serialized instances. And we
can use the XmlWriter.Write DocType to inject our custom DocType. For
example:

XmlSerializer serializer = new XmlSerializer(t ypeof(Group));

Group group = new Group();
StreamWriter sw = new StreamWriter("g roup.xml");
XmlWriter xw = new XmlTextWriter(s w);

xw.WriteDocType ("Group", null, null, "<!ENTITY h 'hardcover'>");

serializer.Seri alize(xw,group) ;

xw.Close();
sw.Close();

HTH. Thanks,
