HowTo: Create RSS Feeds with LINQ to XML (XLinq)
It´s really easy to create XML with LINQ to XML – you can find a HowTo on my german blog.
Now we´ll try to create an RSS Feed with XLINQ
My Projectfiles:
The "Rss.ashx" will create your RSS. At first I want to make sure, that my site-visitors detect my nice RSS Feed automatically:
<head runat="server">
<title>Untitled Page</title>
<link rel="alternate" href="Rss.ashx" type="application/rss+xml" title="" id="rss" />
</head>
This RSS feature is called "RSS Autodiscovery".
The "Rss.ashx":
We create the head (name, declaration and so on) of the RSS XML in the ProcessRequest Method:
public void ProcessRequest(HttpContext context)
{
XDocument document = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XElement("rss",
new XAttribute("version", "2.0"),
new XElement("channel", this.CreateElements())
));
context.Response.ContentType = "text/xml";
document.Save(context.Response.Output);
context.Response.End();
}
At the end of the method the XDocument is saved into the Response.Output. Your RSS items are created in the "CreateElements" Method.
The "CreateElements"-Method:
This method returns IEnumberable<XElement> and the elements will be appended the channel-Element (which is created in the ProcessRequest-Method):
private IEnumerable<XElement> CreateElements()
{
List<XElement> list = new List<XElement>();
for (int i = 1; i < 100; i++)
{
XElement itemElement = new XElement("item",
new XElement("title", i),
new XElement("link", "http://code-inside.de")
);
list.Add(itemElement);
}
return list;
}
That´s it

vLinq is really Great Tool. By using this tool easily create linq query.
I came to know about this tool from
the blog http://www.elevatesoftsolutions.in/post/2008/11/01/LINQ-Query-Builder-Tools.aspx
In this blog one more LINQ Query Builder Tool is mentioned that is LinqPad.
Some demerits are in LinqPad that I came to know after using it. Thus I prefer to use vLinq. Good thing about this that It add-in the VS and query generate can be reused.
Really Great Tool
