  string Rss = ""; 
  if (RssUrl != "") 
  { 
    try 
    { 
      doc.Load(RssUrl); 
      XmlNodeList nodelist = doc.GetElementsByTagName("item"); 
      XmlNodeList objItems1; 
      int i = 1; 
      if (doc.HasChildNodes) 
      { 
        foreach (XmlNode node in nodelist) 
        { 
          string title = ""; // 文章标题

          i += 1; 
          if (node.HasChildNodes) 
          { 
            objItems1 = node.ChildNodes; 
            foreach (XmlNode node1 in objItems1) 
            { 
              switch (node1.Name) 
              { 
                case "title":

                case "description": 
                  content = node1.InnerText; 
                  break;
