In my first article i have explained "How you can create RSS feed using Asp.net". Here in this article i will explain how one can read or consume RSS Feed from Asp.net website. If you look at google reader then you will get a basic idea how one can Reading or Consuming RSS Feed from a RSS Feed link. I don't want to teach you the necessity of reading RSS in this article. So i want to start straight forward. Since in my first article i have created a RSS Feed so that open this project again and add another page and rename it to RSSFeedReader.aspx. In my local PC the RSS Feed link is: "http://localhost:50537/StudyProject/CreateRSS.aspx". Change it by copying the URL for CreateRSS.aspx page. Ok now everything is prepared to read or consume an RSS Feed from Asp.Net web application.
First add a server side table control in your RSSFeedReader.aspx page. So the complete HTML markup will be now:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="RSSFeedReader.aspx.cs" Inherits="RSSFeedReader" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>RSS Feed Reader</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<table cellpadding="0" cellspacing="0">
<tr>
<td>
<table class="NormalText" runat="server" id="tbl_Feed_Reader" cellpadding="0" cellspacing="0">
</table>
</td>
</tr>
</table>
</div>
</form>
</body>
</html>
The complete server side code is given below for Reading & Consuming RSS feed is like below:using System;
using System.Data;
using System.Configuration;
using System.Web.UI.HtmlControls;
using System.Net;
using System.Xml;
using System.IO;
public partial class RSSFeedReader : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
WebRequest MyRssRequest = WebRequest.Create("http://localhost:50537/StudyProject/CreateRSS.aspx");
WebResponse MyRssResponse = MyRssRequest.GetResponse();
Stream MyRssStream = MyRssResponse.GetResponseStream();
// Load previously created XML Document
XmlDocument MyRssDocument = new XmlDocument();
MyRssDocument.Load(MyRssStream);
XmlNodeList MyRssList = MyRssDocument.SelectNodes("rss/channel/item");
string sTitle = "";
string sLink = "";
string sDescription = "";
// Iterate/Loop through RSS Feed items
for (int i = 0; i < MyRssList.Count; i++)
{
XmlNode MyRssDetail;
MyRssDetail = MyRssList.Item(i).SelectSingleNode("title");
if (MyRssDetail != null)
sTitle = MyRssDetail.InnerText;
else
sTitle = "";
MyRssDetail = MyRssList.Item(i).SelectSingleNode("link");
if (MyRssDetail != null)
sLink = MyRssDetail.InnerText;
else
sLink = "";
MyRssDetail = MyRssList.Item(i).SelectSingleNode("description");
if (MyRssDetail != null)
sDescription = MyRssDetail.InnerText;
else
{
sDescription = "";
}
// Now generating HTML table rows and cells based on Title,Link & Description
HtmlTableCell block = new HtmlTableCell();
block.InnerHtml = "<span style='font-weight:bold'><a href='" + sLink + "' target='new'>"+ sTitle + "</a></span>";
HtmlTableRow row = new HtmlTableRow();
row.Cells.Add(block);
tbl_Feed_Reader.Rows.Add(row);
HtmlTableCell block_description = new HtmlTableCell();
block_description.InnerHtml = "<p align='justify'>" + sDescription + "</p>";
HtmlTableRow row2 = new HtmlTableRow();
row2.Cells.Add(block_description);
tbl_Feed_Reader.Rows.Add(row2);
}
}
}
And the Output will be look like this:
So, I hope now you can Make or Create an RSS Feed as well as can read or consume RSS feed using Asp.net. Happy programming.
