How To Read A JSON String From A Webpage?

I am trying to download the contents of this webpage into my program. I have tried using WeblClient.DownloadString, WebClient.DownloadFile, then save it to a file and read it from a local file, but none of this is working. When I use breakpoints in Visual Studio, I see the string is correctly saved, but when I try to print it to a file, or print it to the console, nothing is displayed.

What I am aiming to do is download this webpage's content into a String then parse it with JSON.NET.

Here is my attempt to save it to a file:

         WebClient webpage = new WebClient();


         var html = webpage.DownloadString("http://ift.tt/21FV4CG");
         String k = html;


          File.WriteAllText(@"C:\Users\JCena\Desktop\Hell1o.txt", k);
