Question

I am (trying) to develop a WPF (C#) app that just gets (or at least is supposed to get) my saved bookmarks at Diigo.com profile. The only helpful page i found is this . It says i have to use HTTP Basic authetication to get my self authenticated and make requests then. But don’t understand how C# handles it!. The only solution i came up with below just prints entire HTML source to console window.

string url = "http://www.diigo.com/sign-in";

WebRequest myReq = WebRequest.Create(url);
string usernamePassword = "<username>:<password>";
CedentialCache mycache = new CredentialCache();
mycache.Add(new Uri(url), "Basic", new NetworkCredential("username", "password"));
myReq.Credentials = mycache;
myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new     ASCIIEncoding().GetBytes(usernamePassword)));
 //Send and receive the response
WebResponse wr = myReq.GetResponse();
Stream receiveStream = wr.GetResponseStream();
StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
string content = reader.ReadToEnd();
Console.Write(content);

Here username and password are hardcoded but of course they’ll come from some txtUsername.Text thing. And after that how am i going to read the JSON response and parse it?
What is that i need to do to get my app or myself HTTP basic authenticated?
Any help or suggestion is welcome!

Ok i solved the problem after some (not really some) effort. Code below gets the JSON response from server which can then be parsed using any preferred method.

 string key = "diigo api key";
 string username = "username";
 string pass = "password";
 string url = "https://secure.diigo.com/api/v2/";     
 string requestUrl = url + "bookmarks?key=" + key + "&user=" + username + "&count=5";
 HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(requestUrl);
 string usernamePassword = username + ":" + pass;
 myReq.Timeout = 20000;
 myReq.UserAgent = "Sample VS2010";
 //Use the CredentialCache so we can attach the authentication to the request
 CredentialCache mycache = new CredentialCache();
 //this perform Basic auth
 mycache.Add(new Uri(requestUrl), "Basic", new NetworkCredential(username, pass));
 myReq.Credentials = mycache;
 myReq.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(new ASCIIEncoding().GetBytes(usernamePassword)));
  //Send and receive the response
  WebResponse wr = myReq.GetResponse();
  Stream receiveStream = wr.GetResponseStream();
  StreamReader reader = new StreamReader(receiveStream, Encoding.UTF8);
  string content = reader.ReadToEnd();
  Console.Write(content);

content is the JSON response returned from server
Also this link is useful for getting started with api.
