您需要的是网页抓取:

http://msdn.microsoft.com/en-us/library/system.net. httpwebrequest.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.net. webresponse.aspx [ ^ ].

有关简单的代码示例，请参见:

What you need is called web scraping:
http://en.wikipedia.org/wiki/Web_scraping[^].

You need to use either System.Net.WebClient (for simplest cases) or System.Net.HttpWebRequest with System.Net.WebResponse, in a general case. Please see:
http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.webresponse.aspx[^].

For a simple code sample, please see:
