        // Create a new empty workbook set.
        SpreadsheetGear.IWorkbookSet workbookSet = SpreadsheetGear.Factory.GetWorkbookSet();
        // Create a new empty workbook in the workbook set.
        SpreadsheetGear.IWorkbook workbook = workbookSet.Workbooks.Add();
        // Set Sheet1!A1 to "Hello World!".
        workbook.Worksheets["Sheet1"].Cells["A1"].Value = "Hello World!";
        // Save to memory as an Excel file.
        byte[] buffer = workbook.SaveToMemory(SpreadsheetGear.FileFormat.Excel8);
        // Close the workbook, removing it from the workbook set.
        workbook.Close();
        // Open the saved workbook from memory.
        workbook = workbookSet.Workbooks.OpenFromMemory(buffer);
        // Output Sheet1!A1.
