这样，你就完成了从一个Feed里获取RSS内容的工作。剩下的工作就是调用这个方法来显示Feed的内容了。以下是一个使用ASP.NET完成的完整的例子：

＜%@ Page Language="C#" %＞


＜!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"＞
＜script runat="server"＞
public void ProcessRSSItem(string rssURL)
{
System.Net.WebRequest myRequest = System.Net.WebRequest.Create(rssURL);
System.Net.WebResponse myResponse = myRequest.GetResponse();
System.IO.Stream rssStream = myResponse.GetResponseStream();
System.Xml.XmlDocument rssDoc = new System.Xml.XmlDocument();
rssDoc.Load(rssStream);
System.Xml.XmlNodeList rssItems = rssDoc.SelectNodes("rss/channel/item");
string title = "";
string link = "";
string description = "";
for (int i = 0; i ＜ rssItems.Count; i++)
{
System.Xml.XmlNode rssDetail;
rssDetail = rssItems.Item(i).SelectSingleNode("title");
if (rssDetail != null)
{
title = rssDetail.InnerText;
}
else
{
title = "";
}
rssDetail = rssItems.Item(i).SelectSingleNode("link");
if (rssDetail != null)
{
link = rssDetail.InnerText;
}
else
{
link = "";
}
rssDetail = rssItems.Item(i).SelectSingleNode("description");
if (rssDetail != null)
{
description = rssDetail.InnerText;
}
else
{
description = "";
}
Response.Write("＜p＞＜b＞＜a href='" + link + "' target='new'＞" + title + "＜/a＞＜/b＞＜br/＞");
Response.Write(description + "＜/p＞");
}
}
＜/script＞
＜html xmlns="http://www.w3.org/1999/xhtml"＞
＜head runat="server"＞
＜title＞Untitled Page＜/title＞
＜/head＞
＜body＞
＜form id="form1" runat="server"＞
＜div＞
＜%
string rssURL = "http://www.codeguru.com/icom_includes/feeds/codeguru/rss-all.xml";
Response.Write("＜font size=5＞＜b＞Site: " + rssURL + "＜/b＞＜/font＞＜Br /＞");
ProcessRSSItem(rssURL);
Response.Write("＜hr /＞");
rssURL = "http://www.developer.com/icom_includes/feeds/special/dev-5.xml";
Response.Write("＜font size=5＞＜b＞Site: " + rssURL + "＜/b＞＜/font＞＜Br /＞");
ProcessRSSItem(rssURL);
%＞
＜/div＞
＜/form＞
＜/body＞

＜/html＞

显示结果如下：
