ASP.NET读取RSS的

主要功能代码如下：

/// <summary> 
/// 加载RSS 
/// </summary> 
/// <param name="RssUrl">RSS地址</param> 
/// <param name="RssCount">要提取的文章数量</param> 
/// <returns></returns> 
public string LoadRSS(string RssUrl, int RssCount) 
{ 
  XmlDocument doc = new XmlDocument(); 
  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 
          string link = ""; // 链接 
          string content = ""; // 内容 
          string createDate = ""; // 发表时间 
          i  = 1; 
          if (node.HasChildNodes) 
          { 
            objItems1 = node.ChildNodes; 
            foreach (XmlNode node1 in objItems1) 
            { 
              switch (node1.Name) 
              { 
                case "title": 
                  title = node1.InnerText; 
                  break; 
                case "link": 
                  link = node1.InnerText; 
                  break; 
                case "description": 
                  content = node1.InnerText; 
                  break; 
                case "pubDate": 
                  createDate = node1.InnerText; 
                  break; 
              } 
              if (title != "" && link != "") 
                break; 
            } 
            Rss  = "<a href='https://www.swvq.com/xml_rss-360944.html"   link   "' target='_blank'>"   title   "</a> 发表于 " createDate "<hr/>"; 
            Rss  = content; 
 
          } 
          if (i > RssCount) 
            break; 
        } 
      } 
    } 
    catch (Exception) 
    { 
      Rss = "RSS Feed 源数据出错！"; 
    } 
  } 
  else 
  { 
    Rss = "未找到信息源，您可刷新重试或联系管理员！"; 
  } 
  return Rss;
