      private void Form1_Load(object sender, EventArgs e)        {            webBrowser1.Navigate(Application.StartupPath + @"\i.html");            txtInfo.Text = webBrowser1.DocumentText;        }
private void button2_Click(object sender, EventArgs e)        {                        webBrowser1.Document.InvokeScript("GetCode", new object[] { "1567613","228267824","頂一個","D7D796981B62D318"});            if (webBrowser1.Document.GetElementById("msg") != null)            {                HtmlElement element = webBrowser1.Document.GetElementById("msg");                txtInfo.Text = element.GetAttribute("value");            }               }
 function GetCode(lBdId, lDocId, text, sessionID) {     document.getElementById("msg").value = H2(lBdId + ‘-‘ + lDocId + ‘-‘ + P(text), 16, sessionID);}
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"><html>    <head>        <title></title><script  type="text/javascript" src="i.js"></script>    </head>    <body>    <input type=text id=msg />    </body></html>

以html頁面作為媒介,將返回的值傳遞到html中的控制項,然後在webBrowser中用

 HtmlElement element = webBrowser1.Document.GetElementById("msg");                txtInfo.Text = element.GetAttribute("value")
獲得值
