Introduction
RssNewsFeed is a free .NET library written in C#, which allows you to access an rss feed without going through the hassle of parsing. It will extract feed information, together with the news items, and return them as a collection of objects.
(RSS is a Web content syndication format and is an acronym for Really SimpleSyndication. RSS is a dialect of XML and so all RSS files must conform to the XML 1.0, as published on the World Wide Web Consortium (W3C) website).
Using the library
The RssNewsFeed consists of three public classes, ContentSyndication, SyndicationChannel, and SyndicationItem. A SyndicationChannel object is returned by the ContentSyndicationclass when the GetContent () method is returned, and contains information about the requested channel. It also contains a collection of SyndicationItem objects which contain information about each news item.
To use the library in your application, insert a referenece to the RssNewsFeed.dllby right-clicking on the Reference tree node in the Visual Studio IDE. Select Add Reference, and then select Browse. After you've located the dll, select Ok.
Insert the namespace Cyberise.RssNewsFeed in your application, and create an instance of the ContentSyndication class. See the sample code for more information.
The RSSNewsFeed has its own exception class NewsFeedException, which is thrown in the event of an error. A descriptive message together with the actual exception which caused the error are passed off to the calling application. These can be accessed via the Message() and InnerExecption() methods respectively.
