如何使用NPOI读取文件

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。:)
