下面是使用MScript.ocx组件调用腾讯http://qb.qq.com网站的JS登录密码加密方法：

public bool GetPasswd(string verifyCode, string passwd, ref string passwdValue, ref string errMsg)
        {

            try
            {
                MSScriptControl.ScriptControlClass sc = new MSScriptControl.ScriptControlClass();
                sc.Language = "javascript";
                // 得到JS文件内容
                string html = NetWorkHelper.GetHtml(NetWorkHelper.CreateWebRequest("http://qb.qq.com/js/ps.js", new CookieContainer()));

                sc.AddCode(html);

                string key = "aR!@$34GP<S#@Js;";
                verifyCode += sc.Run("hex_hmac_md5", new object[] { key, passwd }).ToString();

                string b = sc.Run("md5", new object[] { verifyCode }).ToString();
                //md5(str + hex_hmac_md5(key, document.loginForm.Passwd.value));

                #region 不使用MScript.ocx组件
                //WebBrowser webBrowser = new WebBrowser();

                //webBrowser.Navigate("http://qb.qq.com/");

                //while (webBrowser.ReadyState != WebBrowserReadyState.Complete)
                //{
                //    System.Windows.Forms.Application.DoEvents();
                //}

                //HtmlElement heScript = webBrowser.Document.CreateElement("script");

                //heScript.SetAttribute("type", "text/javascript");

                //StringBuilder sb = new StringBuilder();
                //sb.AppendLine("function GetPasswd(verifyCode,passwd) {");
                //sb.AppendLine(" return md5(verifyCode + hex_hmac_md5 ('aR!@$34GP<S#@Js;', passwd));");
                //sb.AppendLine(" };");

                //heScript.SetAttribute("text", sb.ToString());
                //webBrowser.Document.Body.AppendChild(heScript);

                //passwdValue = webBrowser.Document.InvokeScript("GetPasswd", new object[] { verifyCode, passwd }).ToString();
                #endregion
                return true;
            }
            catch (Exception ex)
            {
                errMsg = ex.Message;
                return false;
            }
        }
