C#关于获取网页Activex控件中的代码

小菜最近想做一个页面解析的软件，但是我发现有的网页中如果夹杂了Activex控件的话，这部分的内容就无法获得。用的C#的代码：先用做了一个WebBrowser浏览器，当跳到了想要解析的浏览器时，点击解析，然后获得浏览器里面的源代码，这样就解决了需要Ssesion验证的问题，可以获得需要用户登录后的界面的信息，但是现在，小菜发现获得的源代码里面没有Activex控件中的内容，小菜就是想获得。现在求教。代码如下

private void Analyze_Click(object sender, EventArgs e)

        {

            #region 获得网页的html

            string html = "";

            try

            {

                

                /*string url = WebBrowser.Url.ToString();

                aWebClient.Encoding = System.Text.Encoding.Default;

                html = aWebClient.DownloadString("file:///E:/学习/大三课程/Test.htm");*/

                StreamReader sr = new StreamReader(WebBrowser.DocumentStream, Encoding.Default);

                html = sr.ReadToEnd();

                //html = WebBrowser.DocumentText;

                FileInfo fi = new FileInfo("E:\\test.txt");

                FileStream fs;

                if (fi.Exists)

                {

                    fs = fi.Open(FileMode.CreateNew);

                } 

                else

                {

                    fs = fi.Create();

                }

                StreamWriter bw = new StreamWriter(fs);

                bw.Write(html);

                bw.WriteLine("测试");

                bw.Close();

            }

            {
