Simple RSS

Introduction

Easy to use library to create simple rss feeds and read foreign rss feeds.

All processes are based on XmlSerializer and can be used as an example of how to use XmlSerializer :)

Usage example

To create rss feed you need to fill necessary fields in Rss object and call RSSHelper.WriteRSS to any Stream you wish.

MemoryStream ms = new MemoryStream();
Rss rss = GetFullRSS();
RSSHelper.WriteRSS(rss, ms);
var result = Encoding.UTF8.GetString(ms.GetBuffer()).Trim('\0');
Assert.AreEqual(GetFullRSSText(), result);

To read foreign rss feed you need to get stream with rss data and call RSSHelper.ReadRSS

var request = WebRequest.Create("http://example.org/rss/");
var response = request.GetResponse();
var stream = response.GetResponseStream();
Rss rss = RSSHelper.ReadRSS(stream);
Assert.AreEqual("Example", rss.Channel.Title);

RSS object creating example

Complete rss object will looks like this:

return new Rss
        {
            Channel =
                new RssChannel
                {
                    AtomLink = new RssLink { Href = new RssUrl("http://atomlink.com"), Rel = Rel.self, Type = "text/plain" },

                    Cloud =
                        new RssCloud
