推荐答案

您需要编写屏幕抓取工具，即使用.NET类之一读取HTML并允许访问DOM树的程序.您所阅读页面的大小.尝试在Google上搜索屏幕抓取器"以获取构想.

You need to write a screen scraper, i.e. a program that uses one of the .NET classes to read HTML and gives access to the DOM tree of the page that you read. Try a Google search for "screen scraper" for ideas.

如果您确实需要从网站(而非Web服务或其他网站)获取数据，则确实需要使用Web抓取技术，正如理查德已经指出的那样.我在过去的答案中解释了它们是如何工作的:

如何从另一个站点获取数据 [ ^ ]，
从网页中获取特定数据 [

If you really need to get data from Web sites, not Web services or something else, you really need to use Web scraping techniques, as Richard already pointed out. I explained how they work in my past answers:

How to get the data from another site[^],
get specific data from web page[^].
