推荐答案

WebClient和DownloadString只会将页面内容下载为字符串，为了能够在此页面上运行JavaScript代码，您将需要一个了解以下内容的对象:DOM并可以运行JavaScript，这将是一个浏览器.

WebClient and DownloadString will just download the content of the page as string, to be able to run the JavaScript code on this page, you will need an object which understand DOM and can run JavaScript, this will be a browser.
