1. 通過new建立 AxWebBrowser 

AxSHDocVw.AxWebBrowser webBrowser = new AxSHDocVw.AxWebBrowser();

2 新增載後的完成事件DocumentComplete

    webBrowser.DocumentComplete += WebBrowser_DocumentComplete; 

     3 .加入當前頁面的Controls

           
            this.toolStripContainer.ContentPanel.Controls.Add(webBrowser);
 

      4獲取HTMLDocument元素，通過axWebBrowser1.Document元素直接獲取再轉換

      5 通過execScript的方法新增js指令碼

 /// <summary>
        /// WebBrowser 載入完成後事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        void axWebBrowser1_DocumentComplete(object sender, AxSHDocVw.DWebBrowserEvents2_DocumentCompleteEvent e)
        {
            this.axWebBrowser1.DocumentComplete -= axWebBrowser1_DocumentComplete;
            string jsString = @"function T(){
                                        var ele = window.document.getElementById('kw');
                                        if (ele != null && ele != undefined) {
                                            ele.setAttribute('value', '測試JS指令碼注入AxWebBrowser');
                                        }
                         }   T()";
            mshtml.IHTMLWindow2 win = ((mshtml.HTMLDocumentClass)this.axWebBrowser1.Document).parentWindow;
            win.execScript(jsString, "Javascript");
