增加命名空间: using NPOI.HSSF.UserModel; using System.IO; 实现代码: //文件名称 string fileName = "D:\\test.xls"; FileStream fs = new FileStream(fileName, FileMode.Open, FileAccess.ReadWrite); //读取文件 HSSFWorkbook book = new HSSFWorkbook(fs); fs.Close(); FileStream fs1 = new FileStream(fileName, FileMode.Open, FileAccess.ReadWrite); //写入文件 book.Write(fs1); fs1.Close();
