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 did like David Brown said but I got the following exception.

$exception {"There are multiple root elements. Line , position ."} System.Xml.XmlException

One solution would be to modify the XML file with a root element but that is not always necessary and for an XML stream it might not be possible either. My solution below:

var path = Path.GetFullPath(Path.Combine(Environment.CurrentDirectory, @"..\..\App_Data"));
var directoryInfo = new DirectoryInfo(path);
var fileInfos = directoryInfo.GetFiles("*.xml");

foreach (var fileInfo in fileInfos)
{
    XmlDocument doc = new XmlDocument();
    XmlReaderSettings settings = new XmlReaderSettings();
    settings.ConformanceLevel = ConformanceLevel.Fragment;

    using (XmlReader reader = XmlReader.Create(fileInfo.FullName, settings))
    {
        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {
                var node = doc.ReadNode(reader);
                string json = JsonConvert.SerializeXmlNode(node);
            }
        }
    }
}

Example XML that generates the error:

    
        Text
    


    
        
            Text
        
        
            Text
        
    
    
        Text
