XDocument.Save() without header

Question

I am editing csproj files with Linq-to-XML and need to save the XML without the <?XML?> header.

As XDocument.Save() is missing the necessary option, what's the best way to do this?

Answer 1

You can do this with XmlWriterSettings, and saving the document to an XmlWriter:

        XDocument doc = new XDocument(new XElement("foo",
            new XAttribute("hello","world")));

        XmlWriterSettings settings = new XmlWriterSettings();
        settings.OmitXmlDeclaration = true;
        StringWriter sw = new StringWriter();
        using (XmlWriter xw = XmlWriter.Create(sw, settings))
        // or to write to a file...
        //using (XmlWriter xw = XmlWriter.Create(filePath, settings))
        {
            doc.Save(xw);
        }
        string s = sw.ToString();
