                        {
                            using (OleDbCommand cmdExcel = new OleDbCommand())

                                    DataTable dtExcelSchema;
                                    dtExcelSchema = connExcel.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
                                    connExcel.Close();
