最近开发 Winform 应用程序，涉及到 嵌入Excel 文件。技术验证也快结束，需要整理一下帮助文档了。。

用webBrowser控件 打开Excel 。

       /// </summary>
       public static Microsoft.Office.Interop.Excel.Range range = null;
       /// <summary>
       ///
       /// </summary>
       public static Microsoft.Office.Interop.Excel.Workbook wbb = null;

         /// <summary>
        /// 打开Excel文件
        /// </summary>
        /// <param name="filePath">Excel文件路径</param>
        public void OpenExcel(string filePath)
        {
            strFilePathAndFileName = filePath;

            //Object refmissing = System.Reflection.Missing.Value;

            this.webBrowser1.Navigate(strFilePathAndFileName);

            //object axWebBrowser = this.webBrowser1.ActiveXInstance;
        }

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    Object refmissing = System.Reflection.Missing.Value;

    object[] args = new object[4];

    args[0] = SHDocVw.OLECMDID.OLECMDID_HIDETOOLBARS;

    args[1] = SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER;

    args[2] = refmissing;

    args[3] = refmissing;

    object axWebBrowser = this.webBrowser1.ActiveXInstance;

    axWebBrowser.GetType().InvokeMember("ExecWB", BindingFlags.InvokeMethod, null, axWebBrowser, args);

    object oApplication = axWebBrowser.GetType().InvokeMember("Document", BindingFlags.GetProperty, null, axWebBrowser, null);

    wbb = (Microsoft.Office.Interop.Excel.Workbook)oApplication;

}
