Deserializing JSON using JSon.NET with dynamic data

The simplest method. In this particular case would probably be to go dynamic.

dynamic data = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(json);
var lastRevId = data.query.pages["6695"].lastrevid;

You can reference any element by it's [] name so you can do something like data["query"]["pages"]["6695"]["lastrevid"]. This will get by all those little objects where the name isn't valid in c#.

Here is how you do using https://github.com/facebook-csharp-sdk/simple-json ( https://nuget.org/packages/SimpleJson ).

var text = "{\"query\":{\"pages\":{\"6695\":{\"pageid\":6695,\"ns\":0,\"title\":\"Citadel\",\"touched\":\"2012-01-03T19:16:16Z\",\"lastrevid\":468683764,\"counter\":\"\",\"length\":8899}}}}";

(Using dynamic)

dynamic json = SimpleJson.DeserializeObject(text);
string title = json.query.pages["6695"].title;

foreach (KeyValuePair<string, dynamic> page in json.query.pages)
{
    var id = page.Key;
    var pageId = page.Value.pageid;
    var ns = page.Value.ns;
}

(Using strongly typed classes)

class result
{
    public query query { get; set; }
}
class query
{
    public IDictionary<string, page> pages { get; set; }
}
class page
{
    public long pageid { get; set; }
    public string title { get; set; }
}

var result = SimpleJson.DeserializeObject<result>(text);

[Update]

on windows phone where dynamic is not supported and you don't want to use strongly typed classes.

var json = (IDictionary<string, object>)SimpleJson.DeserializeObject(text);
var query = (IDictionary<string, object>)json["query"];
var pages = (IDictionary<string, object>)query["pages"];
var pageKeys = pages.Keys;
var page = (IDictionary<string, object>)pages["6695"];
var title = (string)page["title"];
