How do you create an indented XML string from an XDocument in c#?

Question

I have an XDocument object and the ToString() method returns XML without any indentation. How do I create a string from this containing indented XML?

edit: I\'m aski

Answer 1

To create a string using an XDocument (rather than an XmlDocument), you can use:

        XDocument doc = new XDocument(
            new XComment("This is a comment"),
            new XElement("Root",
                new XElement("Child1", "data1"),
                new XElement("Child2", "data2")
            )
        );

        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Indent = true;
        StringBuilder sb = new StringBuilder();
        using (XmlWriter writer = XmlTextWriter.Create(sb, settings)) {
            doc.WriteTo(writer);
            writer.Flush();
        }
        string outputXml = sb.ToString();

Edit: Updated to use XmlWriter.Create and a StringBuilder and good form (using).
