Can Web API convert XML into Json?

Question

I've got a legacy web service which I'd like to wrap with a new MVC Web API, question is can I get the ASP.NET Web API to convert my xml into json?

A thought that I had was to use XDocument to create a dynamic object and return that, but when I tried it with an ExpandoObject unfortunately it returned a json object with Key/Value pairs.

Answer 1

Using json.NET you can do it easily:

string result = Newtonsoft.Json.JsonConvert.SerializeXmlNode(xmldocument);

Download Newtonsoft.Json at http://james.newtonking.com/pages/json-net.aspx

Answer 2

You could. One way to do it would be to deserialize the XML into objects and then serialize them again into JSON.

A more efficient (though harder to code up approach) would be to write your own xml-to-json "transcriber" that reads in the XML and spits out JSON.

Just note that not all XML can be represented easily as JSON.
