How to parse JSON data in System.Net.Webrequest reponse

Question

I am trying to call an API which returns the data in JSON format which i need to parse. How to do that in System.Net.Webrequest.. Below is my code

ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback(AcceptAllCertifications);

            request = WebRequest.Create("https://IPAaddress/api/admin/configuration/v1/conference/1/");

            request.Credentials = new NetworkCredential("username", "password");
            // Create POST data and convert it to a byte array.
            request.Method = "GET";          

                    // Set the ContentType property of the WebRequest.
            request.ContentType = "application/json; charset=utf-8";          


            WebResponse response = request.GetResponse();
            // Display the status.
            Console.WriteLine(((HttpWebResponse)response).StatusDescription);
            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream();
            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);
            // Read the content.
            string responseFromServer = reader.ReadToEnd();

            // Display the content.
            Console.WriteLine(responseFromServer);
            // Clean up the streams.
            reader.Close();
            dataStream.Close();
            response.Close();

Webrequest just returns a response from a remote resource. You need to parse the JSON yourself, like using the DataContractJsonSerializer, or Json.Net (http://www.newtonsoft.com/json)

Do i need to create a data contract class? – RackM Sep 08 '16 at 07:27
The easiest way is to include the Newtonsoft package in your project: in Package Manager Console, select the project, then run `Install-Package Newtonsoft.Json`. Using the data contract types is appropriate when you want to enforce contracts, which may not be what you want. – DvS Sep 08 '16 at 10:34
