How do you fill a List<Request>() for a BatchUpdateSpreadsheetRequest to update multiple rows/columns/cells in a google spreadsheet in C#

Question

BatchUpdateSpreadsheetRequest requestBody = new BatchUpdateSpreadsheetRequest();
            requestBody.Requests = new List<Request>();
            Request r = new Request();
            requestBody.Requests.Add(r);
            r.UpdateCells = new UpdateCellsRequest();

            var gc = new GridCoordinate();
            gc.ColumnIndex = 0;
            gc.RowIndex = 0;
            gc.SheetId = 0;

            r.UpdateCells.Start = gc;
            r.UpdateCells.Fields = "*";
            r.UpdateCells.Rows = new List<RowData>();

            //TODO:: loop through record set to update cell data (cd) with values to insert
            SqlDataReader reader = default(SqlDataReader);
            reader = o_cSQL.RunSPReturnDataReader("Shippments", 40997, sNow, sNow);
            while (reader.Read())
            {

                var rd = new RowData();
                r.UpdateCells.Rows.Add(rd);
                rd.Values = new List<CellData>();
                var cd = new CellData();
                cd.UserEnteredValue = new ExtendedValue();
                // the next line is only updating the first cell (first row/first column) 
                //how to you get multiple CellData created for a single row ?
                cd.UserEnteredValue.StringValue = reader["new_attn"].ToString();
                rd.Values.Add(cd);
            }
            SpreadsheetsResource.BatchUpdateRequest batchRequest = service.Spreadsheets.BatchUpdate(requestBody, spreadsheetId);
            batchRequest.Execute();

Can someone please help with how you get multiple cells updated per row? I know I'm only showing one value from my 'reader' from the database, that's where I got stuck in that I don't know how to specifically pinpoint each cell of my spreadsheet. I'm pulling an unknown recordset size from a database and need to enter it on a google spreadsheet. I know how many columns.

Answer 1

since I know my columns, I just kept making new CellData(); items for each RowData item in my reader.Read() while loop. Worked first time!
