winform导入excel

winfrom导入excel内容，要求能够excel中多个工作簿的内容。代码如下：

 

#region 导入excel数据

        private void button2_Click(object sender, EventArgs e)

        {

            OpenFileDialog openFileDialog = new OpenFileDialog();

             openFileDialog.Filter = "表格文件 (*.xls)|*.xls";

             openFileDialog.RestoreDirectory = true;

             openFileDialog.FilterIndex = 1;

             if (openFileDialog.ShowDialog() == DialogResult.OK)

             {

                 Import(openFileDialog.FileName);

             }

        }

                //Excel就好比一个数据源一般使用

                //这里可以根据判断excel文件是03的还是07的，然后写相应的连接字符串

                string strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + filePath + ";" + "Extended Properties=Excel 8.0;";

                OleDbConnection con = new OleDbConnection(strConn);

                string[] names = GetExcelSheetNames(con);

                if (names.Length > 0)
