Posted 2020-10-09

 1     NPOI.HSSF.UserModel.HSSFWorkbook book = new NPOI.HSSF.UserModel.HSSFWorkbook();
 2             NPOI.SS.UserModel.ISheet sheet1 = book.CreateSheet("Sheet1");
 3             List<NBAModel> list = new List<NBAModel>();
 4             //创建栏目
 5             NPOI.SS.UserModel.IRow row = sheet1.CreateRow(0);
 6             row.CreateCell(0).SetCellValue("编号");
 7             row.CreateCell(1).SetCellValue("姓名");
 8             for (int i = 0; i < list.Count; i++)
 9             {
10                 NPOI.SS.UserModel.IRow rowtemp = sheet1.CreateRow(i + 1);
11                 rowtemp.CreateCell(0).SetCellValue(list[i].Id.ToString());
12                 rowtemp.CreateCell(1).SetCellValue(list[i].Name.ToString());
13             }
14             // 写入到客户端  
15             System.IO.MemoryStream ms = new System.IO.MemoryStream();
16             book.Write(ms);
17             ms.Seek(0, SeekOrigin.Begin);
18             Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}.xls", "****总表" + DateTime.Now.ToString("yyyyMMddHHmmssfff")));
19             Response.BinaryWrite(ms.ToArray());
20             book = null;
21             ms.Close();
22             ms.Dispose();
