How to read Google AJAX Feed API results from C# code?

c#, google-ajax-api, json.net

Solution

I've just looked at the examples, and here is how I'd go about it.

- Construct the feed Url (read the documentation)

- Use the WebClient to Download the URL as a String.

- Use Json.NET to reads the string.

- Use a for-loop to read each entries

For example, a quick untested hack:

// 1.
var url = "'http://ajax.googleapis.com/ajax/services/feed/load?q=http%3A%2F%2Fwww.digg.com%2Frss%2Findex.xml&v=1.0";

// 2.
var wc = new WebClient();
var rawFeedData = wc.DownloadString(url);

// 3.
var feedContent = JObject.Parse(rawFeedData);

// ...
var entries = feedContent["entries"];

for (int i = 0; i < entries.Length; i++) {
    var entry = entries[i];

    // insert entry into your desired collection
}

If however, you want strongly-typed class, you must first make a class that "looks like" the data that is returned from the feed api first, i.e.

public class FeedApiResult {
    public FeedApiFeedObj responseData { get; set; }
    // snip ...
}

public class FeedApiFeedObj {
    public string title { get; set; }
    public string link { get; set; }
    // snip ...
}

Then in step #3, you can use the deserializing method like this:

var apiResult = JsonConvert.DeserializeObject<FeedApiResult>(feedContent)

...

Hope this helps!

Problem

I want to use Goolge AJAX Feed API in my C# console application to save return feeds as C# collection so i can use this .net collcetion in my .net application. I noticed google give a Java Access Code Snippets but I have no idea how to coding it in C#. I know there is a very good .net opensource library Json.NET we can use to read and write JSON formatted data. Can someone give me an exmpale how to use C# and Json.NET play with Google AJAX Feed API? Final Solution: ``` public class FeedApiResult { public ResponseData responseData { get; set; } public string responseDetails { get; set; } public string responseStatus { get; set; } } public class ResponseData { public Feed feed { get; set; } } public class Feed { public string title { get; set; } public string link { get; set; } public string author { get; set; } public string description { get; set; } public string type { get; set; } public List<Entry> entries { get; set; } } public class Entry { public string title { get; set; } public string link { get; set; } public string author { get; set; } public string publishedDate { get; set; } public string contentSnippet { get; set; } public string content { get; set; } } var url = "http://ajax.googleapis.com/ajax/services/feed/load?q=http%3A%2F%2Fwww.digg.com%2Frss%2Findex.xml&v=1.0"; var wc = new WebClient(); var rawFeedData = wc.DownloadString(url); //You can use System.Web.Script.Serialization if you don't want to use Json.NET JavaScriptSerializer ser = new JavaScriptSerializer(); FeedApiResult foo = ser.Deserialize<FeedApiResult>(rawFeedData); //Json.NET also return you the same strong typed object var apiResult = JsonConvert.DeserializeObject<FeedApiResult>(rawFeedData); ```
