推荐答案

在这里使用Web浏览器几乎无济于事.您需要直接使用HTTP.您只需要使用类System.Net.HttpWebRequest发送HTTP请求，获取HTTP响应(System.Net.HttpWebResponse)并分析结果，对其进行解析，等等.请参见:
http://msdn.microsoft.com/en-us/library/system.net. httpwebrequest.aspx [ ^ ](在此处找到代码示例)，
http://msdn.microsoft.com/en-us/library/system.net. httpwebresponse.aspx [ ^ ].

基本上，您将需要使用 Web抓取技术的一些元素:

从网页中获取特定数据 [

Using a Web browser here will hardly help you much. You need to work with HTTP directly. All you need is to use the class System.Net.HttpWebRequest to send HTTP request, get HTTP response (System.Net.HttpWebResponse) and analyze the result, parse it, etc. Please see:
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^] (find a code sample here),
http://msdn.microsoft.com/en-us/library/system.net.httpwebresponse.aspx[^].

Basically, you will need to use some elements of Web scraping techniques:

For some more detail, please see my past answers:

get specific data from web page[^].
