RSS Feeds

News right at your fingertips!

This feature provides a set of functions that allow you to get a list of articles from an RSS feed from a single site.

---

Usage

If you want to get all RSS feeds from a single site, you can use the RSSTools class from the Nettify.Rss namespace. Just follow the below steps:

1

Creating a new instance

Create a new instance of the RSSFeed class that contains the necessary constructor.

public RSSFeed(string FeedUrl, RSSFeedType FeedType)

2

Refresh the instance to get articles

Call either Refresh() or RefreshAsync() to get the latest information about your feed, depending on the scenario.

If you're either doing web development, or you're developing in an asynchronous program, call the RefreshAsync() function where appropriate.

Structure

The RSS feed class contains a structure that is explained when you expand one of the following items.

The constructor

The constructor provides the following required arguments:

Argument	Description
FeedUrl	Specifies the URL to the RSS feed, for example, https://www.techrepublic.com/rssfeeds/articles/
FeedType	Specifies the feed type to parse

Feed types

FeedType can be one of the following:

Feed type	Description
RSS2	Assumes that the RSS feed in the given URL is an RSS 2 feed
RSS1	Assumes that the RSS feed in the given URL is an RSS 1 feed
Atom	Assumes that the RSS feed in the given URL is an Atom feed
Infer	Automatically detects the RSS feed type

RSS feed instance

For the RSS feed info, RSSFeed contains the following properties:

Property	Description
FeedUrl	URL to the feed
FeedType	Feed type as described above
FeedTitle	Feed title provided by the host
FeedDescription	Feed description provided by the host
FeedArticles	List of feed articles

Feed article list

In the RSS feed instance, FeedArticles is a list of feed articles, RSSArticle, that you can enumerate within the for loop, for example:

var feed = new RSSFeed("feedurl", RSSFeedType.Infer);
foreach (RSSArticle article in feed.FeedArticles)
{
    // Your code here
}

This class contains the following properties:

Property	Description
ArticleTitle	Title of the article

Searching RSS feeds

When it comes to searching RSS feeds, Nettify uses Feedly to give you a functionality that allows you to search Feedly for all the RSS feeds. For instance, if you're searching for Linux using this feature, it'll return all feeds that have to do with Linux. Check out Feedly's website if you don't know what it is yet:

Feedly: Track the topics and trends that matter to youfeedly.com

To get articles from the RSS feeds that are found within a search term, follow these steps:

1

Get a list of RSS feed sites

Use one of the following functions:

• GetRssFeeds()

• GetRssFeedsAsync()

Once you call one of these functions, you can use this array of SearcherInstance to get information about the resultant feeds.

If you're either doing web development, or you're developing in an asynchronous program, call the GetRssFeedsAsync() function where appropriate.

2

Obtain an RSS feed instance from the searcher

Use one of the following functions:

• GetFeedFromSearcher()

• GetFeedFromSearcherAsync()

Once you call one of these functions, you can get an instance of RSSFeed that you can use to get articles.

If you're either doing web development, or you're developing in an asynchronous program, call the GetFeedFromSearcherAsync() function where appropriate.

If you don't want to obtain an RSS feed from the searcher, you can use it for something else.

Searcher instance properties

A SearcherInstance class contains the following properties:

Property	Description
Description	Gets the first line of the description
FullDescription	Gets the whole feed description
