PhantomJS wrapper for .NET (C#)

Scraping webpage generated by javascript with C#

Easier Method

It appears there is a nuget package for the phantomjs, such that you don't need the hub:

Install web driver:

Install-Package Selenium.WebDriver

Install embedded exe:

Install-Package phantomjs.exe

The code:

var driver = new PhantomJSDriver();
driver.Url = http://www.yoursite.co.uk/;
driver.Navigate();
//the driver can now provide you with what you need (it will execute the script)
//get the source of the page
var source = driver.PageSource;
//fully navigate the dom
var pathElement = driver.FindElementById("some-id");
