winfrom的webbrowser在IE6和IE7中正常，但在IE8中不行

[bbb332]

在一个form中的webbrowser传递用户名和密码

        private void Fopenoa_Load(object sender, EventArgs e)
        {
            //取得用户名密码
            string filetext = "";
            string filepath = path + "//config.txt";
            string username = "";
            string pwd = "";
            FileStream fs1 = new FileStream(filepath, FileMode.Open, FileAccess.Read);
            StreamReader sr = new StreamReader(fs1, System.Text.Encoding.GetEncoding("GB2312"));
            string line = sr.ReadLine();
            int i = 1;
            while (line != null)
            {
                filetext += line + " ";
                line = sr.ReadLine();
                if (i == 1)
                {
                    username = filetext;
                }
                else
                {
                    pwd = filetext;
                }
                filetext = "";
                i = i + 1;
            }
            sr.Close();
            fs1.Close();
            webBrowser1.Navigate("http://127.0.0.1/mainfram_oa.aspx?tusername=" + username + "&" + "tpwd=" + pwd + "");
        }

在mainfram_oa.aspx中的代码是

protected void Page_Load(object sender, EventArgs e)
    {
            Session.Clear();
            string username = Request.QueryString["tusername"].ToString();
            string pwd = Request.QueryString["tpwd"].ToString();
            if (username.ToString().Trim() == "")
            {
                Response.Write("<script>function window.onload(){mainfram.location.href='login.aspx';}</script>");
                return;
            }
            if (username.ToString().Trim() == "姓名")
            {
                Response.Write("<script>function window.onload(){mainfram.location.href='login.aspx';}</script>");
                return;
            }
            DateTime ndate = DateTime.Now;
            //密码使用md5加密
            iSunHash my_iSunHash_class = new iSunHash();
            pwd = my_iSunHash_class.strHashMd5(pwd, Encoding.ASCII);
            string strSQL = "SELECT * FROM dbo.tb_user INNER JOIN dbo.tb_department ON dbo.tb_user.departmentcode = dbo.tb_department.departmentcode INNER JOIN dbo.Tb_role ON dbo.tb_user.Tu_roleid = dbo.Tb_role.Tr_roleid INNER JOIN dbo.Tb_position ON dbo.tb_user.Tu_position = dbo.Tb_position.Tp_zhiweiid WHERE (dbo.tb_user.username = @username) and (dbo.tb_user.password = @pwd)";
            Session["susername"] = "";
            SqlCommand cmd = new SqlCommand(strSQL, connection);
            cmd.Parameters.AddWithValue("@username", username); 
            cmd.Parameters.AddWithValue("@pwd", pwd);
            connection.Open();
            SqlDataReader myReader = cmd.ExecuteReader();
            if (myReader.Read())
            {
                Session["suserid"] = myReader["userid"].ToString();
                Session["struename"] = myReader["truename"].ToString();
                Session["szhiweiname"] = myReader["Tp_zhiweiname"].ToString();
                Session["spositionid"] = myReader["Tp_zhiweiid"].ToString();
                Session["srolename"] = myReader["Tr_rolename"].ToString();
                Session["sdepname"] = myReader["departmentname"].ToString();
                Session["sdepcode"] = myReader["departmentcode"].ToString();
                Session["spagename"] = "回到首页";
                Session["susername"] = username;

            }
            myReader.Close();
            cmd.Dispose();
            connection.Close();
        if (Session["susername"].ToString() != "")
        {
            Response.Write("<script>function window.onload(){mainfram.location.href='default.aspx';}</script>");
        }
        else
        {
            Response.Write("<script>function window.onload(){mainfram.location.href='login.aspx';}</script>");

        }

    }

，在ie6和ie7中是可以取得用户名和密码进入default.aspx页面的，而在ie8中运行winfrom程序，第一次是可以进入的，但是第一次之后就不能进入'default.aspx'了，而是进入'login.aspx'页面。有谁知道为什么呀，谢谢了。。。

在aspx的前台页面上head中加入

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

把ie8渲染成ie7

解决了webBrowser1.Navigate("http://127.0.0.1/mainfram_oa.aspx?tusername=" + username + "&" + "tpwd=" + pwd + "&t="+Datetime.Now.Tostring());
