Json.Net deserialize JSON objects with index as name
c#, json, json.net, xamarin
Solution
You don't need `FeaturedArticles` class, you can deserialize the JSON into a `Dictionary<string, Articles>` like this:
private void fetchFeaturedArticles()
{
var client = new RestClient (_featuredArticlesJsonUrl);
var request = new RestRequest (Method.GET);
var response = client.Execute (request);
Dictionary<string, Articles> _featuredArticles = JsonConvert.DeserializeObject<Dictionary<string, Articles>>(response.Content);
foreach (string key in _featuredArticles.Keys)
{
Console.WriteLine(_featuredArticles[key].Title);
}
}

Problem
I am attempting to parse JSON from a web service using Json.NET, the web service returns data in the following format: ``` { "0": { "ID": 193, "Title": "Title 193", "Description": "Description 193", "Order": 5, "Hyperlink": "http://someurl.com" }, "1": { "ID": 228, "Title": "Title 228", "Description": "Description 228", "Order": 4, "Hyperlink": "http://someurl.com" }, "2": { "ID": 234, "Title": "Title 234", "Description": "Description 234", "Order": 3, "Hyperlink": "http://someurl.com" } } ``` I used json2sharp to generate a class from the JSON: ``` public class __invalid_type__0 { public int ID { get; set; } public string Title { get; set; } public string Description { get; set; } public int Order { get; set; } public string Hyperlink { get; set; } } public class __invalid_type__1 { public int ID { get; set; } public string Title { get; set; } public string Description { get; set; } public int Order { get; set; } public string Hyperlink { get; set; } } public class __invalid_type__2 { public int ID { get; set; } public string Title { get; set; } public string Description { get; set; } public int Order { get; set; } public string Hyperlink { get; set; } } public class RootObject { public __invalid_type__0 __invalid_name__0 { get; set; } public __invalid_type__1 __invalid_name__1 { get; set; } public __invalid_type__2 __invalid_name__2 { get; set; } } ``` I then cleaned up the class and was left with the following: ``` public class Articles { public int ID { get; set; } public string Title { get; set; } public string Description { get; set; } public int Order { get; set; } public string Hyperlink { get; set; } } public class FeaturedArticles { public List<Articles> articles { get; set; } } ``` When I attempt to load the data into my singleton for use in the app: ``` private void fetchFeaturedArticles() { var client = new RestClient (_featuredArticlesJsonUrl); var request = new RestRequest (Method.GET); var response = client.Execute (request); _featuredArticles = JsonConvert.DeserializeObject<FeaturedArticles> (response.Content); foreach (Articles a in _featuredArticles.Articles) Console.WriteLine (a.Title); } ``` I find that the Articles do not get deserialized. I've verified that the JSON data is returned from the web service. I believe the issue exists in the structure of my JSON feed, where each item returned from the feed is given a name which equals the index the item is being returned as. I am new to using Json.NET so I'm not sure how I should proceed; I cannot change the structure of the JSON feed but need to consume it's data. Anyone have any recommendations?
