How to return a DataTable in json and xml format in response to a Get request?

Question

ASP.NET

I receive the table from a DB.
How to format it as a response in the form of json and xml?
Will these lines be enough if the $format variable is specified in the GET request?:

GlobalConfiguration.Configuration.Formatters.JsonFormatter.AddQueryStringMapping("$format", "json", "application/json");
GlobalConfiguration.Configuration.Formatters.XmlFormatter.AddQueryStringMapping("$format", "xml", "application/xml");

Answer 1

I would prefer json. Recently, the majority is inclined to use it, after all, it is more familiar to JS. Even Microsoft, in some of their products, are switching from xml to json.
