急，如何获取HtmlElement.InvokeMember之后的HTML数据

kensouterry 2009-12-28 02:47:08

一个网页程序（界面上有1个TextBox和1个Button）
主体代码：



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



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();

        }



    }

}
