[twitter-dev] The remote server returned an error: (401) Unauthorized. + asp.net

[Mansi]

I have to post text on Twitter through my web site.
For that I've created one application on Twitter. And have done all
the related changes in site source code.

I am using .net Framework 2.0.

But having issue while redirecting to Twitter
(oAuth.AuthorizationLinkGet()).
It throws bug The remote server returned an error: (401) Unauthorized
in below code. (oAuthTwitter.cs file)
  public string WebResponseGet(HttpWebRequest webRequest)
        {
            StreamReader responseReader = null;
            string responseData = "";

            try
            {
                responseReader = new
StreamReader(webRequest.GetResponse().GetResponseStream()); //HERE IT
THROWS EXCEPTION.
                responseData = responseReader.ReadToEnd();
            }
            catch
            {
                throw;
            }
            finally
            {
                webRequest.GetResponse().GetResponseStream().Close();
                responseReader.Close();
                responseReader = null;
            }

            return responseData;
        }



What causes this bug? And what is the solution?
