How to print <?xml version="1.0"?> using XDocument

Question

Is there any way to have an XDocument print the xml version when using the ToString method? Have it output something like this:

<?xml version="1.0"?> <!DOCTYPE ELMResponse [ ]> <Response> <Error> ...

I have the following:

var xdoc = new XDocument(new XDocumentType("Response", null, null, "\n"), ...

which will print this which is fine, but it is missing the "<?xml version" as stated above.

<!DOCTYPE ELMResponse [ ]> <Response> <Error> ...

I know that you can do this by outputting it manually my self. Just wanted to know if it was possible by using XDocument.

Answer 1

By using XDeclaration. This will add the declaration.

But with ToString() you will not get the desired output.

You need to use XDocument.Save() with one of his methods.

Full sample:

var doc = new XDocument(         new XDeclaration("1.0", "utf-16", "yes"),          new XElement("blah", "blih"));  var wr = new StringWriter(); doc.Save(wr); Console.Write(wr.ToString());
