Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];
Cell cellA1 = worksheet[0, 0]; // Cell A1
Cell cellB2 = worksheet.Cells["B2"]; // Cell B2
Cell cellC3 = worksheet.Cells[2, 2]; // Cell C3
Cell cellD4 = worksheet.Rows[3][3]; // Cell D4
Cell cellE5 = worksheet.Rows[4]["E"]; // Cell E5
Cell cellF6 = worksheet.Rows["6"][5]; // Cell F6
Cell cellG7 = worksheet.Columns[6][6]; // Cell G7
Cell cellH8 = worksheet.Columns["H"][7]; // Cell H8
Cell cellI9 = worksheet.Columns["I"]["9"]; // Cell I9
// Access a cell from the range of cells.
Cell cellB5 = worksheet.Range["B3:D8"][6]; // Cell B5
Cell cellD6 = worksheet.Range["B3:D8"][3, 2]; // Cell D6

访问一系列Cell(Range)

using DevExpress.Spreadsheet;
// ...
Workbook workbook = new Workbook();
Worksheet worksheet = workbook.Worksheets[0];
// A range that includes cells from the top left cell (A1) to the bottom right cell (B5).
Range rangeA1B5 = worksheet["A1:B5"];
// A rectangular range that includes cells from the top left cell (C4) to the bottom right cell (E7).

// The C4:E7 cell range located in the "Sheet3" worksheet.
Range rangeSheet3C4E7 = workbook.Range["Sheet3!C4:E7"];
// A range that contains a single cell (E7).
Range rangeE7 = worksheet.Range["E7"];
// A range that includes the entire column A.
Range rangeColumnA = worksheet.Range["A:A"];
// A range that includes the entire row 5.

Range rangeC6D9E7 = worksheet.Range.Parse("C6:D9:E7");
// A rectangular range whose left column index is 0, top row index is 0,
// right column index is 3 and bottom row index is 2. This is the A1:D3 cell range.
Range rangeA1D3 = worksheet.Range.FromLTRB(0, 0, 3, 2);
// A range that includes the intersection of two ranges: C5:E10 and E9:G13.
