急，如何获取HtmlElement.InvokeMember之后的HTML数据
一个网页程序（界面上有1个TextBox和1个Button）
主体代码：

C# code

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class _Default : System.Web.UI.Page {    protected void Page_Load(object sender, EventArgs e)    {        this.TextBox1.Text="Hello,World";        Button1.Click += new EventHandler(Button1_Click);    }    void Button1_Click(object sender, EventArgs e)    {        //throw new NotImplementedException();        this.TextBox1.Text = "Hello World,Change!";    }}

现在我要在一个控制台程序里面调用此Web程序中Button控件的Click方法

C# code

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Forms;using System.Threading;using System.Net;using System.IO;using System.Security.Permissions;namespace 模拟点击操作_Console{    class Program    {        WebBrowser wb;        //返回网页内容字符串        StringBuilder allInfo = new StringBuilder();        //Html 文档对象        HtmlDocument doc;        /// <summary>        /// 截取某网页中的所有数据--测试函数        /// </summary>        /// <returns></returns>        public string TestObtainWebpageContent()        {            string address = @"http://localhost:1106/TestSite";            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);            HttpWebResponse response = (HttpWebResponse)request.GetResponse();            //response.ContentType = "text/xml";            char[] buf = new char[256];            StreamReader resStream = new StreamReader(response.GetResponseStream(),Encoding.GetEncoding("big5"));                        int count = resStream.Read(buf, 0, buf.Length);            while (count > 0)            {                // Dumps the 256 characters on a string and displays the string to the console.                String str = new String(buf, 0, count);                allInfo.Append(str);                count = resStream.Read(buf, 0, count);            }            resStream.Close();            return allInfo.ToString();        }        /// <summary>        /// 主调函数        /// </summary>        private void ExecuteSearch()        {            wb = new WebBrowser();            wb.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(wb_DocumentCompleted);            wb.ScriptErrorsSuppressed = true;            //导航到指定的URL地址中HTML源码---？？此时给定某URL            TestObtainWebpageContent();            wb.Navigate("D:\\12-28\\模拟点击操作_Console\\test.html");            //初始化HtmlDocument对象            doc=wb.Document.OpenNew(true);            doc.Write(allInfo.ToString());            wb_DocumentCompleted(null, null);            wb.Dispose();        }        /// <summary>        /// 文档加载完成事件        /// </summary>        /// <param name="sender"></param>        /// <param name="e"></param>        void wb_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)        {            //throw new NotImplementedException();            TestObtainElement();        }        /// <summary>        /// 读取下一页的内容并进行显示--测试函数        /// </summary>        private void TestObtainElement()        {            string s = wb.DocumentText;            HtmlElement elem = wb.Document.Body.All["Button1"];            elem.InvokeMember("Click");            //IHTMLElement element = (IHTMLElement)input.DomElement;            //element.Click();            string s1 = wb.DocumentText;            Console.WriteLine(wb.DocumentText);        }        [STAThread]        //[PermissionSet(SecurityAction.Demand, Name = "FullTrust ")]         [System.Runtime.InteropServices.ComVisibleAttribute(true)]         static void Main(string[] args)        {            Program p1 = new Program();            p1.ExecuteSearch();                        Console.ReadLine();        }    }} 
 

问题在TestObtainElement()函数中，调用了Button1控件的Click事件后，从WebBrowser中得到的DocumentText数据与调用之前的WebBrowser.DocumentText一样，我想应该是调用Click事件出了错。
希望各位兄弟姐妹能帮我解决一下！
