            //create connection
            OleDbConnection oleDBConnection = new OleDbConnection(connectionString);
            oleDBConnection.Open();

            //create the adapter with the select to get 
            OleDbDataAdapter adapter = new OleDbDataAdapter("select * from [Sheet1$]", oleDBConnection);

            // Create the dataset and fill it by using the adapter.
