2.代碼

using NPOI.HSSF.UserModel;
using NPOI.SS.UserModel;
       
　　　　 public FileResult ExportExcel()
        {
            List<DispatchViewModel> list = DispatchDAL.GetDispatchPagedList(m => true, 1, 999999999);            
            HSSFWorkbook hssfWorkbook = OutputSearchResult(list);
            byte[] data = null;
            using (MemoryStream ms = new MemoryStream())
            {
                hssfWorkbook.Write(ms);
                ms.Flush();
                ms.Position = 0;
                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("維修報表");
            IRow rowHeader = sheet.CreateRow(0);
            rowHeader.CreateCell(0, CellType.String).SetCellValue("維修編號");
            rowHeader.CreateCell(1, CellType.String).SetCellValue("姓名");
            rowHeader.CreateCell(2, CellType.String).SetCellValue("手機號碼");

            rowHeader.CreateCell(5, CellType.String).SetCellValue("區");
            rowHeader.CreateCell(6, CellType.String).SetCellValue("詳細地址");for (int i = 0; i < list.Count; i++)
            {
                IRow dataRow = sheet.CreateRow(i + 1);
                dataRow.CreateCell(0, CellType.String).SetCellValue(list[i].ID);
                dataRow.CreateCell(1, CellType.String).SetCellValue(list[i].ContactsName);
                dataRow.CreateCell(2, CellType.String).SetCellValue(list[i].Phone);
                dataRow.CreateCell(3, CellType.String).SetCellValue(list[i].ProvinceName);
                dataRow.CreateCell(4, CellType.String).SetCellValue(list[i].CityName);
                dataRow.CreateCell(5, CellType.String).SetCellValue(list[i].AreaName);
                dataRow.CreateCell(6, CellType.String).SetCellValue(list[i].Address);
            }
