I have an Excel Cell Address like A1, A2. How do I access this cell programmatically using NPOI framework in C#?
Some Java POI example code I found:
CellReference cr = new CellReference("A1");
row = mySheet.getRow(cr.getRow());
cell = row.getCell(cr.getCol());
The Java code you found translates 1:1 into C#:
CellReference
Row
and Col
from that CellReference to lookup the actual cell.Here is some sample code
var workbook = new XSSFWorkbook(stream);
var sheet = workbook.GetSheetAt(0);
var cr = new CellReference("D5");
var row = sheet.GetRow(cr.Row);
var cell = row.GetCell(cr.Col);
Console.Write(cell.StringCellValue);
Do note that referencing an empty Cell will result in an exception. Excel doesn't store non-used cells internally, and (N)POI does not attempt to hide that fact from the developer.
