        string result = "";
    WebRequest req = WebRequest.Create("Url here");
        //i'm getting error from the following line
    WebResponse webresponse = req.GetResponse();
    Stream ReceiveStream = webresponse.GetResponseStream();

    Byte[] read = new Byte[512];
    int bytes = ReceiveStream.Read(read, 0, 512);
    while (bytes > 0)
    {
        Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
        result = result + encode.GetString(read, 0, bytes);
        bytes = ReceiveStream.Read(read, 0, 512);

        // the response contains name value pairs separated by commas
    string[] response = result.Split(',');
    string key;
    string valuePart;
    NameValueCollection nr = new NameValueCollection();
    int i = 0;
    foreach (string xx in response)
    {
        i = xx.IndexOf("=");
        key = xx.Substring(0,i);
        valuePart = xx.Substring(i + 1);
        nr.Add(key,valuePart);
