看的数据中提取SDK ，它允许通过Htm​​lProcessor类发布的数据。您还可以添加如果是在图书馆错过了你的工作​​项目这里。

I need to write standalone application which will "browse" external resource. Is there lib in C# which automatically handles cookies and supports JavaScript (through JS is not required I believe)? The main goal is to keep session alive and submitting forms so I could pass multistep registration process or "browse" web site after login. I reviewed Html Agility Pack but it looks like it doesn't contain functionality I need - form submitting or cookie support.

Thanks, Artem.

Look at Data Extracting SDK, which allows to post data via HtmlProcessor class. Also you can add your work item here if it is missed in the library.
