How to programmatically create RSS feed using C# and XmlTextWriter

Recently I was trying to submit our technology website www.Techulator.com to Google News. I learnt that Google need a separate RSS Feed that provide the feeds of all posts that can be classified as "News". Since our regular RSS feed does not provide just the News posts, I decided to create a separate feed that include only the News items. Since this is a custom C# implementation in our ASP.NET project, I explored a bit and ended up writing a few lines of code.

Here is the code I used to generate RSS feed from our site:

Response.Clear();
Response.ContentType = "text/xml";

System.Xml.XmlTextWriter rssWriter = new 
      System.Xml.XmlTextWriter(Response.OutputStream, System.Text.Encoding.UTF8);

rssWriter.WriteStartDocument();

rssWriter.WriteStartElement("rss");
rssWriter.WriteAttributeString("version", "2.0");

rssWriter.WriteStartElement("channel");
rssWriter.WriteElementString("title", "Technology News");
rssWriter.WriteElementString("link", "http://www.dotnetspider.com");
rssWriter.WriteElementString("description", "Latest Technology News from dotnetspider.com");
rssWriter.WriteElementString("copyright", "Copyright 2012 dotnetspider.com.");

// Write all Posts from table to the rss feed
foreach (DataRow row in rssTable.Rows)
{
    rssWriter.WriteStartElement("item");
    rssWriter.WriteElementString("title", (string)row["Title"]);
    rssWriter.WriteElementString("link", 
      "http://www.dotnetspider.com/resources/ViewResource.aspx?Id=" +
      (int)row["Id"]);
    rssWriter.WriteElementString("description", (string)row["Description"]);
    rssWriter.WriteElementString("author", (string)row["Name"]);
    rssWriter.WriteElementString("pubDate", 
                ((DateTime)row["PostedDate"]).ToString("r"));
    rssWriter.WriteEndElement();
}

// Close xml elements
rssWriter.WriteEndElement();
rssWriter.WriteEndElement();
rssWriter.WriteEndDocument();
rssWriter.Flush();
rssWriter.Close();

Response.End();
