NBoilerpipe was a C# port of the java-based Boilerpipe project. I've forked it from Organix/NBoilerpipe and removed the Mono and SharpZipLib dependencies.
This project now builds in Visual Studio 2012 and should be useful as a drop-in library.
NBoilerpipe is a C# port of boilerpipe 1.2 (http://code.google.com/p/boilerpipe/) library. Most of the code is converted with the Sharpen tool (https://github.com/slluis/sharpen). The code uses the Sharpen libary (with modification) from NGit project (https://github.com/slluis/ngit) and HmtlAgilityPack (http://htmlagilitypack.codeplex.com/).
NBoilerpipe is only been tested with Mono.
Usage:
using NBoilerpipe.Extractors;
...
String html = GetHtmlText();
var text = ArticleExtractor.INSTANCE.GetText (html);
//var text = DefaultExtractor.INSTANCE.GetText (html);
