porting this php code to c#

Question

I'm having trouble porting this code below to c#. my main trouble is with the $fb_activity_array.

            $fb_activity_message = '{*actor*} played this game';
            $fb_activity_array = json_encode(array('message' => $fb_activity_message, 'action_link' => array('text' => 'Play Now','href' => 'http://yoururltoplaygamegere')));

Answer 1

Is this by any chance a Facebook app? It looks like you're trying to create a Stream post. If so, I recommend using the .NET Facebook API, which contains functions to do what you want, as well as some JSON formatting utilities if you need to do something manually.

This isn't a perfect example, but this might put you on the right path. First create an object to hold your data.

public class activity
{
    public activity(string message, object action_link)
    {
        Message = message;
        Action_Link = action_link;
    }

    public string Message { get; set; }
    public object Action_Link { get; set; }

}

public class action_link
{
    public string Text { get; set; }
    public string Href { get; set; }

    public action_link(string text, string href)
    {
        Text = text;
        Href = href;
    }
}

Then you want to make a class like this to serialize it:

using System;
using System.Web;
using System.Web.Script.Serialzation;
     public class activityHandler : IHttpHandler
        {
        public void ProcessRequest (HttpContext context) {
                string message = "{*actor*} played this game";
                string text = "Play Now";
                string href = "http://yoururltoplaygamegere";

                action_link link = new action_link(text, href);
                activity act = new activity(message, link);

                JavaScriptSerializer serializer = new JavaScriptSerializer();
                context.Response.Write(serializer.Serialize(act));
                context.Response.ContentType = "application/json";

        }
        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

}

This will most likely give you the JSON structure you are looking for when serializing. You could turn the action_link object into a collection if that conforms to the standard you are looking to achieve so that you could have multiple action_link objects per activity object and so on and so forth. You can learn more about the serialization used in this example here:

Hope this helps.
