Basically there is a lot of stuff in the .Net 3.5 framework that does the grunt-work of parsing and representing feeds; it's not hard to write a 30-line app that takes in a feed URL and downloads the feed and prints the title and author of all the items, for example. (Works for RSS 2.0 (not others!) or Atom.)

blocks|key|1620929|text|正如另一个帖子所推荐的那样，SyndicationFeed类和Argotic是最好的选择。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1620930|如果性能是个问题，那么SyndicationFeed类会更好。我的基准测试是在我的硬件上比Argotic快9倍。|1620931|我在SyndicationFeed类中遇到的问题是它能够成功地解析来自网络的任何随机提要，它经常会因为XmlException而失败。|1620932|对于我的用途，我坚持使用Argotic。毕竟，它是开源的，所以如果需要，我可以随时进行更改。|1620933|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

As another poster recommended, the SyndicationFeed class and Argotic are the best alternatives. 

If performance is an issue, the SyndicationFeed class will be much better. I benchmarked it as being about 9 times faster than Argotic on my hardware. 

The problem I've had with the SyndicationFeed class has been its ability to successfully parse any random feed from the 'net. It fails with an XmlException surprisingly often.

For my uses, I'm sticking with Argotic. After all, it is open source, so I can always make changes if I need to.

blocks|key|1620763|text|如果在不使用任何库的情况下编写功能齐全的阅读器，还需要考虑ATOM提要。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1620764|entityMap|0|LINK|mutability|MUTABLE|url|http://www.atomenabled.org/developers/syndication/atom-format-spec.php^0|T|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

blocks|key|1620835|text|RSS本身非常简单。只有一个频道的XML描述，以及该频道上的项目列表(可能有附加到每个项目的文件)。跟踪更新有点棘手，管理编码和发布时间/日期也很棘手。真正的噩梦是不同网站对RSS格式的不同“解释”。如果您真的在编写一个提要阅读器，您可能希望从解析Atom开始，因为它是一种更标准化的格式，并且可能会使您更快，因为有了一个可以分支到RSS的良好设计。但实际上，您应该只使用RSS解析库--最好是最兼容的解析库(但不要花钱购买RSS库；它们已经足够常见了)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1620836|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

RSS itself is really simple. Just an XML description of a channel, and a list of items on that channel (possibly with files attached to each item). Keeping track of updates is a little tricky, and managing encodings and post times/dates is tricky too though. The real nightmare is all the different "interpretations" of the RSS format that different sites use. If you're really writing a feed reader, you might want to start with parsing Atom, as it's a more standardised format, and might get you further faster, with a good design to branch off into RSS from. But really, you should just use an RSS parsing library -- preferably the most compatible one available (but don't pay for an RSS library; they're common enough).

blocks|key|1406085|text|RSS是一种XML方言，所以如果您了解XML，就解决了部分问题。如果你想开始你的项目，考虑看看已经存在的开源项目：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1406086|http://www.codeplex.com/site/search?projectSearchText=RSS%2520Reader|offset|length|1406087|CodePlex+(上图)是一个很好的起点，因为大多数项目都将在C#中。|1406088|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeplex.com/site/search?projectSearchText=RSS%2520Reader^0|0|0|1U|0|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@$D|R|E|S|1|T]]|A|$]]|$1|F|3|G|5|6|7|U|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|I|$J|$5|K|L|M|A|$N|O]]]]

RSS is an XML dialect, so if you know XML, you have part of the problem solved. If you want a start on your project, consider looking at the open source projects already out there:

<a href="http://www.codeplex.com/site/search?projectSearchText=RSS%20Reader" rel="nofollow noreferrer">http://www.codeplex.com/site/search?projectSearchText=RSS%20Reader</a>

CodePlex (above) is a good place to start, as the majority of the projects will be in C#.

Consider reading the source code for <a href="http://rssbandit.org/" rel="nofollow noreferrer">RSS Bandit</a>, which is a C# Winforms (possibly soon WPF) RSS Reader.

You should get some good ideas by just stepping through the application.

blocks|key|1621023|text|我一直在使用RSS，我发现使用RssSyndication类通常更容易解析ATOM提要。对于RSS2.0规范，如果提要实际上是有效的，那么从URI加载XDocument并根据需要解析数据也同样容易。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1621024|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I've been working with RSS quite a bit and have found that ATOM feeds are typically easier to parse using the RssSyndication class. For RSS 2.0 specifications, if the feed is in fact valid, then it's just as easy to load an XDocument from the URI, and parse the data as needed.

blocks|key|1406288|text|如果您不能使用System.ServiceModel.Syndication.Syndicationfeed，例如，因为您正在使用PCL+(可移植类库)。我写了一个：FeedParserPCL。你可以在NuGet上找到它。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1406289|entityMap|0|LINK|mutability|MUTABLE|url|https://github.com/aloisdg/FeedParserPCL|1|https://www.nuget.org/packages/FeedParserPCL/^0|7|1B|2B|D|0|2T|5|1|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]]|D|@$9|S|A|T|1|U]|$9|V|A|W|1|X]]|E|$]]|$1|F|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]|N|$5|I|J|K|E|$L|O]]]]

If you cant use <code>System.ServiceModel.Syndication.Syndicationfeed</code>, for example because you are using a PCL (Portable Class Library).

You can find it on <a href="https://www.nuget.org/packages/FeedParserPCL/" rel="nofollow">NuGet</a>.

I have been wanting to make a RSS reader for a while now (just for fun), but I don't have the slightest idea of where to start. I don't understand anything about RSS. Are there any good tutorials on RSS and how to implement it in an application (not a tutorial on how to make a RSS reader, that would be too easy).

How can I get started making a C# RSS Reader?

我想做一个RSS阅读器已经有一段时间了(只是为了好玩)，但我一点也不知道从哪里开始。我对RSS一无所知。有没有关于RSS的好教程，以及如何在应用程序中实现它(不是关于如何制作RSS阅读器的教程，那太简单了)。
