    <p>I'm trying to deserialize some JSON data into objects for an application. Up until now it's been fine because the properties on the JSON data was static (key with a value). Now I've got a result where the key is a dynamic piece of data.</p> <p>Here's an example JSON url:</p> <p><a href="http://en.wikipedia.org/w/api.php?action=query&amp;format=json&amp;pageids=6695&amp;prop=info">http://en.wikipedia.org/w/api.php?action=query&amp;format=json&amp;pageids=6695&amp;prop=info</a></p> <p>The resulting JSON for this is:</p> <pre><code>{ "query" : { "pages" : { "6695" : { "counter" : "", "lastrevid" : 468683764, "length" : 8899, "ns" : 0, "pageid" : 6695, "title" : "Citadel", "touched" : "2012-01-03T19:16:16Z" } } } } </code></pre> <p>Okay, that's great except I can't deserialize the "pages" data into an object. If I were to define a class for the pages it would have to look like this:</p> <pre><code>public class 6695 { public string counter { get; set; } public int lastrevid { get; set; } public int length { get; set; } public int ns { get; set; } public int pageid { get; set; } public string title { get; set; } public string touched { get; set; } } </code></pre> <p>In order to deserialze the contents (using JsonConvert.Deserialize(jsondata)) and we all know we can't have a class called 6695. Not only that, the name of the class would have to be different (for example pageid=7145 would have to be the 7145 class).</p> <p>I can seem to pluck some values out if I use something like JObject.Parse(content) and then access items as JArrays but it's pretty ugly and I'm still stuck on trying to get out the data from the pages array.</p> <p>Looking for someone to help with this. I don't think it's uncommon, it's just not JSON data I've come across before and not sure how to handle it.</p> <p>Thanks!</p> <p>PS forgot to mention this is on Windows Phone 7 so "dynamic" isn't available!</p>

    1. COWouldn't the 6695, just be property name, rather than a class name? Still a problem, but maybe you can do search and replace of the numeric property into some fixed name. I'm not sure how Json.NET handles this but maybe you can try deserialize it as a dictionary of a specific object type?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
