How to convert JSON to XML or XML to JSON?

Question

I started to use Json.NET to convert a string in JSON format to object or viceversa. I am not sure in the Json.NET framework, is it possible to convert a string in JSON to X

Answer 1

I searched for a long time to find alternative code to the accepted solution in the hopes of not using an external assembly/project. I came up with the following thanks to the source code of the DynamicJson project:

public XmlDocument JsonToXML(string json)
{
    XmlDocument doc = new XmlDocument();

    using (var reader = JsonReaderWriterFactory.CreateJsonReader(Encoding.UTF8.GetBytes(json), XmlDictionaryReaderQuotas.Max))
    {
        XElement xml = XElement.Load(reader);
        doc.LoadXml(xml.ToString());
    }

    return doc;
}

Note: I wanted an XmlDocument rather than an XElement for xPath purposes. Also, this code obviously only goes from JSON to XML, there are various ways to do the opposite.
