But open the page is still all over the rss,xml and other eye-catching icons, open the page Mathon browser is also a hint of a new RSS connection, a previous item

The eye needs to write one himself. NET generates the following classes of RSS information, as follows:

1using System;

3using System.Collections;
4using System.Globalization;
5using system.web;

Depending on your specific needs, you can read the data to the list, then iterate through the list, call the above method, and generate an XML string.

This string is the XML string used by Rs. You can also enter the ASPX file, and then use the <link type= "Application/rss+xml" rel= "alternate" href= "rssfeed.aspx" > Call the RSS file, The toilet software will automatically prompt for RRs information.
