EXCEL--VSTO项目搭建

程序集引用 ： Microsoft.Office.Interop.Excel

1、选择.net framework4.6 框架新建VSTO项目

2、添加可视化Ribbon

3、设置Ribbon菜单的ControlIdType=Custom（使菜单作为独立的选项卡显示）

4、获取属性  public Excel.Application ExcelApp= Globals.ThisAddIn.Application;

        private void button1_Click(object sender, RibbonControlEventArgs e)
        {

            ExcelApp = Globals.ThisAddIn.Application;
            int TempInt = Globals.ThisAddIn.Application.Hwnd;
            RefreshRightPane(TempInt);
            //设置面板可见性
            RightPane.Visible = true;
        }        
//窗体句柄字典
        private Dictionary<int, CustomTaskPane> HwndPaneDic = new Dictionary<int, CustomTaskPane> { };
        private CustomTaskPane RightPane { get; set; } //侧边面板
  /// <summary>
        /// 重新绑定右侧面板
        /// </summary>
        /// <param name="HwndInt">当前窗体的句柄</param>
        private void RefreshRightPane(int HwndInt)
        {
            if (HwndPaneDic.ContainsKey(HwndInt))
            {
                RightPane = HwndPaneDic[HwndInt];
            }
            else
