Web-Scraping Framework C#/.Net/Mono
Iron Webscraper makes C# development of screen scraping and data-mining applications possible by providing a C#/VB interface for developers to write web scraping workflows that mimic human browsing behavior. Available as a .Net DLL & Nuget package.
The C# web-scraper framework is a sophisticated set of C# screen scraping classes (also available on Nuget) which make extracting data form web applications and turning it into .Net objects, JSON, CSVs and Spreadsheets enjoyable. The Iron WebScraper DLL to your project brings in behind the scenes management of threading, document parsing, proxies, headers and cookies so that you can focus on linear scraping logic which is easy to code and debug.
