下面简单阅读示例：
using NPOI.HSSF.UserModel;using NPOI.SS.UserModel;//.....private void button1_Click(object sender, EventArgs e){ HSSFWorkbook hssfwb; using (FileStream file = new FileStream(@"c:test.xls", FileMode.Open, FileAccess.Read)) { hssfwb= new HSSFWorkbook(file); } ISheet sheet = hssfwb.GetSheet("Arkusz1"); for (int row = 0; row <= sheet.LastRowNum; row++) { if (sheet.GetRow(row) != null) //null is when the row only contains empty cells { MessageBox.Show(string.Format("Row {0} = {1}", row, sheet.GetRow(row).GetCell(0).StringCellValue)); } }}顺便说一句：在NPOI网站这里在下载部分有例子包-
的C＃示例一包。如果尚未尝试，请尝试一下。:)
