NPOI 获取行数、获取列数

一、NPOI获取行数

可以使用NPOI库中的ISheet类中的LastRowNum属性获取Excel文件中行数

using (FileStream fs =new FileStream(filePath, FileMode.Open, FileAccess.Read))
{
    IWorkbook workbook = new HSSFWorkbook(fs);
    ISheet sheet = workbook.GetSheetAt(0);
    int rowCount = sheet.LastRowNum;
}

二、NPOI获取列数

1.row获取列数，表头数量 

row.Cells.Capacity

       //读取行
                IRow row = sheet.GetRow(i);
                if (row.Cells[0] == null)
                    continue;
                var value = row.Cells[0].ToString();
row.Cells.Capacity

2.row获取每行单元格数量，去掉null的单元格数量

row.Cells.Count
