• C# NPOI-Excel导出 (List集合导出)


    1、添加NPOI包,添加引用。

     

    2、前端调用方法

    <button type="button" class="btn btn-primary" onclick="ExportToExcel()">导出Excel</button>

    <script type="text/javascript">

    //导出Excel
    function ExportToExcel() {
    window.location.href = "/Home/DataExport"
    }
    </script>

    3、后端写法

    #region Excel导出
            public FileResult DataExport()
            {
                List<Phone> ExListInfo = new List<Phone>();
                Phone p = new Phone("小米5", "小米", "3500");
                Phone p1 = new Phone("小米2A", "小米", "2500");
                Phone p2 = new Phone("荣耀20Pro", "华为", "3500");
                ExListInfo.Add(p);
                ExListInfo.Add(p1);
                ExListInfo.Add(p2);
    
                //ExportExcel(ExListInfo);
    
                //创建Excel文件的对象
                NPOI.HSSF.UserModel.HSSFWorkbook book = new NPOI.HSSF.UserModel.HSSFWorkbook();
                //添加一个sheet
                ISheet sheet1 = book.CreateSheet("Sheet1");
    
                //貌似这里可以设置各种样式字体颜色背景等,但是不是很方便,这里就不设置了
    
                //给sheet1添加第一行的头部标题
                IRow row1 = sheet1.CreateRow(0);
                row1.CreateCell(0).SetCellValue("手机名称");
                row1.CreateCell(1).SetCellValue("手机型号");
                row1.CreateCell(2).SetCellValue("手机价格");
                //....N行
    
                //将数据逐步写入sheet1各个行
                for (int i = 0; i < ExListInfo.Count; i++)
                {
                    IRow rowtemp = sheet1.CreateRow(i + 1);
                    rowtemp.CreateCell(0).SetCellValue(ExListInfo[i].PhoneName);
                    rowtemp.CreateCell(1).SetCellValue(ExListInfo[i].PhoneType);
                    rowtemp.CreateCell(2).SetCellValue(ExListInfo[i].PhonePrice);
                    //....N行
                }
                // 写入到客户端 
                MemoryStream ms = new MemoryStream();
                book.Write(ms);
                ms.Seek(0, SeekOrigin.Begin);
                DateTime dt = DateTime.Now;
                string dateTime = dt.ToString("yyMMddHHmmssfff");
                string fileName = "手清价格一览表" + dateTime + ".xls";
    
                return File(ms, "application/vnd.ms-excel", fileName);
    
    
    
            }
    
            #endregion
