winform导入excel到access数据库中

        项目中用到了此功能。把大概做法跟大家共享下，希望对大家有所帮助。也给自己总结一下，激励自己再接再厉。下面中部分代码被汉字替换了，主要考虑到公司的产品权，希望谅解。
        /// <summary>
        /// 点击打开按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnOpen_Click(object sender, EventArgs e)
        {
            try
            {
                OpenFileDialog ofd = new OpenFileDialog();
                ofd.Filter = "Excel文件(*.xls)|*.xls";
                //标题
                ofd.Title = "打开";
                //多选
                ofd.Multiselect = false;
                //默认值
                ofd.FilterIndex = 1;
                ofd.InitialDirectory = System.AppDomain.CurrentDomain.BaseDirectory;
