关键代码:

 public  static ArrayList read(string url, HttpWebRequest request, bool isFirst)
        {
            Stream stream = null;
            Uri uri = new Uri(url);
            switch (uri.Scheme)
            {
                case "file":
                    break;
                case "https":
                    goto case "http";
                case "http":
                    if (request == null)
                        request = (HttpWebRequest)WebRequest.Create(uri);
                    try
                    {
                        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
                        try
                        {
                            if (response.ContentEncoding != "")
                        Encoding.GetEncoding(response.ContentEncoding);
                        }
                        catch { }
                        stream = response.GetResponseStream();
                    }
                    catch (WebException we)
                    {
                    }
                    break;
            }
            ArrayList list = null;
            if (stream != null)
            {
                RssSina rssSina = new RssSina(stream);

                list= rssSina.Read(isFirst);
                rssSina.Close();
                                      }
            return list;
           
        }






分析 新浪的RSS  就是用的这个方法了。

        /// <returns></returns>
