[解决办法]
webBrowser控件操作动态html 

哈哈 为了今天，我几年前就特地准备好了代码示例了，今天终于用到了，赶快去我的资源里下载区吧。
[解决办法]
1.抓取页面源码，webbroser,webclient，WebRequest 等等
2.分析源码，利用正则或者DOM对象找到所需数据

 string url = "http://news.sina.com.cn/china/ ";//要获取的页面地址
                WebRequest req = WebRequest.Create(url);
                using (WebResponse res = req.GetResponse())    // GetResponse blocks until the response arrives
                {
                    using (Stream ReceiveStream = res.GetResponseStream())    // Read the stream into a string
                    {
                        StreamReader sr = new StreamReader(ReceiveStream);
                        string resultstring = sr.ReadToEnd();
                        var list = Regex.Matches(resultstring, @"(?i)<a[^>]*?href=(['""]?)(?<Url>[^'""]*?/(\d+?)\.shtml)\1[^>]*?>(?<Text>[^<>]*?)</a>").OfType<Match>().Select(a=>a.Groups["Url"].Value).ToList();
                        /*
