2.代码

using NPOI.HSSF.UserModel;
using NPOI.SS.UserModel;

　　　　 public FileResult ExportExcel()
        {
            List<DispatchViewModel> list = DispatchDAL.GetDispatchPagedList(m => true, , );
            HSSFWorkbook hssfWorkbook = OutputSearchResult(list);
            byte[] data = null;
            using (MemoryStream ms = new MemoryStream())
            {
                hssfWorkbook.Write(ms);
                ms.Flush();
                ms.Position = ;
                data = ms.GetBuffer();
            }
            return File(data, "application/vnd.ms-excel", DateTime.Now.Ticks + ".xls");
        }

        public HSSFWorkbook OutputSearchResult(List<DispatchViewModel> list)
        {

            HSSFWorkbook hssfWorkbook = new HSSFWorkbook();
            ISheet sheet = hssfWorkbook.CreateSheet("维修报表");
            IRow rowHeader = sheet.CreateRow();
            rowHeader.CreateCell(, CellType.String).SetCellValue("维修编号");
            rowHeader.CreateCell(, CellType.String).SetCellValue("姓名");
            rowHeader.CreateCell(, CellType.String).SetCellValue("手机号码");
            rowHeader.CreateCell(, CellType.String).SetCellValue("省");
            rowHeader.CreateCell(, CellType.String).SetCellValue("市");
            rowHeader.CreateCell(, CellType.String).SetCellValue("区");
            rowHeader.CreateCell(, CellType.String).SetCellValue("详细地址");for (int i = ; i < list.Count; i++)
            {
                IRow dataRow = sheet.CreateRow(i + );
                dataRow.CreateCell(, CellType.String).SetCellValue(list[i].ID);
                dataRow.CreateCell(, CellType.String).SetCellValue(list[i].ContactsName);

                dataRow.CreateCell(, CellType.String).SetCellValue(list[i].AreaName);
                dataRow.CreateCell(, CellType.String).SetCellValue(list[i].Address);
            }
            return hssfWorkbook;
        }
