想把別的網站的rss新聞整合到自己的網頁，剛學，一直都不會。今天終于成功了！可能這個方法有點笨！思路是把xml文件下載到本地，然后再讀本地XML，就簡單了！不知道是否有更簡單的方法，希望高手賜教！

核心代碼如下：
（用webRequest得到指定頁的內容，然后用FileStream寫到本地文件中）
核心部份（下載RSS鏈接的XML文件到本地！）
 
       PRivate void download_Click(object sender, System.EventArgs e)
                {
                        Encoding sjis = Encoding.GetEncoding("utf-8");
                        FileStream fs = new FileStream(Server.MapPath(".")+"//sina.xml",FileMode.Create,Fileaccess.Write);
                        //建立StreamWriter為寫做準備
                        StreamWriter rw = new StreamWriter(fs,sjis);
                       
                        string rl;
                                //創建WebRequest對象
                                WebRequest myReq = WebRequest.Create("讀取遠程文件(新浪新聞)，然后用FileStream將文件保存到本地！
                                //創建WebResponse對象
                                WebResponse myRes = myReq.GetResponse();
                                //獲取Stream
                                Stream resStream = myRes.GetResponseStream();
                                //以下操作為讀取Stream對象中的內容
                                StreamReader sr = new StreamReader(resStream,sjis);
                                StringBuilder sb = new StringBuilder();
                                while((rl=sr.ReadLine())!=null)
                                {
                                        rw.WriteLine(rl);                                       
                                }                               
                        myRes.Close();       
                        rw.Flush();
                        //關閉rw對象
                        rw.Close();
                        fs.Close();
                        msg.Text="下載成功！";

                        }

可以在程序中加入判斷，幾個小時下一次，或者一天下一次！
