使用NPOI导出Excel文件,本实例使用了ASP.NET MVC。
1、使用NPOI导出Excel文件
实例:导出商品列表。
要求:1、通过NPOI导出导出商品列表信息;
2、使用Excel函数计算商品总金额;
在Controllers控制器目录中创建ExportController.cs控制器
- using System.IO;
- using NPOI;
- using NPOI.POIFS;
- using NPOI.HSSF;
- using NPOI.Util;
- using NPOI.HSSF.UserModel;
- using NPOI.HPSF;
- using NPOI.SS.UserModel;
- using NPOI.SS.Util;
- using NPOI.HSSF.Util;
- /// <summary>
- /// 导出商品列表
- /// </summary>
- public FileResult ExportProduct()
- {
- //创建一个新的xls文件
- HSSFWorkbook workbook = new HSSFWorkbook();
- //创建DocumentSummaryInformation(选填)
- DocumentSummaryInformation dsi = PropertySetFactory.CreateDocumentSummaryInformation();
- dsi.Company = "深圳市电子商务有限公司";
- dsi.Category = "报表";
- //创建SummaryInformation(选填)
- SummaryInformation si = PropertySetFactory.CreateSummaryInformation();
- si.Subject = "商品列表";
- si.Title = "商品列表导出";
- si.Author = "Kevin Pan";
- //把创建好的对象赋给Workbook
- workbook.DocumentSummaryInformation = dsi;
- workbook.SummaryInformation = si;
- //创建一个Sheet
- ISheet sheet = workbook.CreateSheet("Sheet1");
- sheet.DefaultRowHeight = 300;
- //创建标题
- IRow rowTitle = sheet.CreateRow(0);
- rowTitle.Height = 500;
- ICellStyle styleTitle = workbook.CreateCellStyle();
- styleTitle.Alignment = HorizontalAlignment.Center;
- styleTitle.VerticalAlignment = VerticalAlignment.Center;
- IFont fontTitle = workbook.CreateFont();
- fontTitle.FontName = "宋体";
- fontTitle.FontHeightInPoints = 18;
- styleTitle.SetFont(fontTitle);
- ICell cellTitle = rowTitle.CreateCell(0);
- cellTitle.SetCellValue("商品列表");
- cellTitle.CellStyle = styleTitle;
- sheet.AddMergedRegion(new CellRangeAddress(0, 0, 0, 5)); //合并单元格
- //创建表格样式
- IFont font = workbook.CreateFont();
- font.FontName = "宋体";
- font.FontHeightInPoints = 10;
- ICellStyle style = workbook.CreateCellStyle(); ;
- style.BorderBottom = NPOI.SS.UserModel.BorderStyle.Thin;
- style.BottomBorderColor = HSSFColor.Black.Index;
- style.BorderLeft = NPOI.SS.UserModel.BorderStyle.Thin;
- style.LeftBorderColor = HSSFColor.Black.Index;
- style.BorderRight = NPOI.SS.UserModel.BorderStyle.Thin;
- style.RightBorderColor = HSSFColor.Black.Index;
- style.BorderTop = NPOI.SS.UserModel.BorderStyle.Thin;
- style.TopBorderColor = HSSFColor.Black.Index;
- style.Alignment = HorizontalAlignment.Center;
- style.SetFont(font);
- //创建表头
- IRow rowHead = sheet.CreateRow(1);
- rowHead.CreateCell(0).SetCellValue("序号");
- rowHead.GetCell(0).CellStyle = style;
- sheet.SetColumnWidth(0, 256 * 5);
- rowHead.CreateCell(1).SetCellValue("商品名称");
- rowHead.GetCell(1).CellStyle = style;
- sheet.SetColumnWidth(1, 256 * 25);
- rowHead.CreateCell(2).SetCellValue("商品品牌");
- rowHead.GetCell(2).CellStyle = style;
- sheet.SetColumnWidth(2, 256 * 20);
- rowHead.CreateCell(3).SetCellValue("商品价格");
- rowHead.GetCell(3).CellStyle = style;
- sheet.SetColumnWidth(3, 256 * 15);
- rowHead.CreateCell(4).SetCellValue("数量");
- rowHead.GetCell(4).CellStyle = style;
- sheet.SetColumnWidth(3, 256 * 10);
- rowHead.CreateCell(5).SetCellValue("总金额");
- rowHead.GetCell(5).CellStyle = style;
- sheet.SetColumnWidth(3, 256 * 15);
- //获取商品列表数据
- List<ProductModel> dataList = GetProductList();
- //绑定表内容
- int rowindex = 2;
- int xh = 1;
- foreach (var item in dataList)
- {
- IRow rowContent = sheet.CreateRow(rowindex);
- rowContent.CreateCell(0).SetCellValue(xh);
- rowContent.GetCell(0).CellStyle = style;
- rowContent.CreateCell(1).SetCellValue(item.ProductName);
- rowContent.GetCell(1).CellStyle = style;
- rowContent.CreateCell(2).SetCellValue(item.ProductBrand);
- rowContent.GetCell(2).CellStyle = style;
- rowContent.CreateCell(3).SetCellValue(item.ProductPrice.ToString());
- rowContent.GetCell(3).CellStyle = style;
- rowContent.CreateCell(4).SetCellValue(item.Quantity.ToString());
- rowContent.GetCell(4).CellStyle = style;
- //设置函数,计算总金额
- rowContent.CreateCell(5).SetCellFormula(String.Format("$D{0}*$E{0}", rowindex+1));
- rowContent.GetCell(5).CellStyle = style;
- rowindex++;
- xh++;
- }
- //输出
- System.IO.MemoryStream ms = new System.IO.MemoryStream();
- workbook.Write(ms);
- ms.Seek(0, SeekOrigin.Begin);
- return File(ms, "application/vnd.ms-excel", "商品列表.xls");
- }
2、基于.xls模板导出Excel文件
实例:基于.xls模板导出订单信息(如图 1)
要求:1、使用基于.xls模板导出订单信息;
2、使用Excel函数计算订单和商品的总金额;
图 1 基于.xls模板导出订单信息
- /// <summary>
- /// 导出订单信息
- /// </summary>
- public FileResult ExportOrder()
- {
- //获取订单信息
- OrderModel order = GetOrderInfo();
- //获取Excel模板
- string fileName = AppDomain.CurrentDomain.SetupInformation.ApplicationBase + @"/Template/order.xls";
- FileStream file = new FileStream(fileName, FileMode.Open, FileAccess.Read);
- //通过模板创建一个xls文件
- HSSFWorkbook workbook = new HSSFWorkbook(file);
- //获取Sheet
- ISheet sheet = workbook.GetSheet("Sheet1");
- //导出订单信息
- sheet.GetRow(1).CreateCell(1).SetCellValue(order.OrderNo);
- sheet.GetRow(1).CreateCell(3).SetCellValue(order.OrderTime.ToString("yyyy-MM-dd HH:mm:ss"));
- sheet.GetRow(1).CreateCell(5).SetCellFormula("SUM(F6:F100)"); //设置函数,计算订单总金额
- sheet.GetRow(2).CreateCell(1).SetCellValue(order.CustomName);
- sheet.GetRow(2).CreateCell(3).SetCellValue(order.CustomAddress);
- //导出产品列表
- if (order.ProductList != null && order.ProductList.Count > 0)
- {
- //创建表头
- IRow rowHead = sheet.CreateRow(4);
- rowHead.CreateCell(0).SetCellValue("序号");
- sheet.SetColumnWidth(0, 256 * 15);
- rowHead.CreateCell(1).SetCellValue("商品名称");
- sheet.SetColumnWidth(1, 256 * 25);
- rowHead.CreateCell(2).SetCellValue("商品品牌");
- sheet.SetColumnWidth(2, 256 * 20);
- rowHead.CreateCell(3).SetCellValue("商品价格");
- sheet.SetColumnWidth(3, 256 * 15);
- rowHead.CreateCell(4).SetCellValue("数量");
- sheet.SetColumnWidth(3, 256 * 10);
- rowHead.CreateCell(5).SetCellValue("总金额");
- sheet.SetColumnWidth(3, 256 * 15);
- //绑定表内容
- int rowindex = 5;
- int xh = 1;
- foreach (var item in order.ProductList)
- {
- IRow rowContent = sheet.CreateRow(rowindex);
- rowContent.CreateCell(0).SetCellValue(xh);
- rowContent.CreateCell(1).SetCellValue(item.ProductName);
- rowContent.CreateCell(2).SetCellValue(item.ProductBrand);
- rowContent.CreateCell(3).SetCellValue(item.ProductPrice.ToString());
- rowContent.CreateCell(4).SetCellValue(item.Quantity.ToString());
- rowContent.CreateCell(5).SetCellFormula(String.Format("$D{0}*$E{0}", rowindex + 1)); //设置函数,计算总金额
- rowindex++;
- xh++;
- }
- }
- //输出
- System.IO.MemoryStream ms = new System.IO.MemoryStream();
- workbook.Write(ms);
- ms.Seek(0, SeekOrigin.Begin);
- return File(ms, "application/vnd.ms-excel", "订单信息.xls");
- }
3、其他代码
3.1 实体类
在Models模型目录中创建ProductModel.cs和OrderModel.cs实体类
- /// <summary>
- /// 商品信息实体类
- /// </summary>
- public class ProductModel
- {
- /// <summary>
- /// 商品名称
- /// </summary>
- public string ProductName { get; set; }
- /// <summary>
- /// 商品品牌
- /// </summary>
- public string ProductBrand { get; set; }
- /// <summary>
- /// 商品价格
- /// </summary>
- public decimal ProductPrice { get; set; }
- /// <summary>
- /// 数量
- /// </summary>
- public int Quantity { get; set; }
- }
- /// <summary>
- /// 订单信息实体类
- /// </summary>
- public class OrderModel
- {
- /// <summary>
- /// 订单编号
- /// </summary>
- public string OrderNo { get; set; }
- /// <summary>
- /// 下单时间
- /// </summary>
- public DateTime OrderTime { get; set; }
- /// <summary>
- /// 总金额
- /// </summary>
- public decimal Amount { get; set; }
- /// <summary>
- /// 客户名称
- /// </summary>
- public string CustomName { get; set; }

- /// <summary>
- /// 商品列表
- /// </summary>
- public List<ProductModel> ProductList { get; set; }
- }
3.2 获取商品和订单数据
- /// <summary>
- /// 获取商品列表
- /// </summary>
- public List<ProductModel> GetProductList()
- {
- List<ProductModel> productList = new List<ProductModel>();
- ProductModel product1 = new ProductModel(){
- ProductName = "苹果IPhone6手机",
- ProductBrand = "苹果",
- ProductPrice = 4999,
- Quantity = 4
- };
- ProductModel product2 = new ProductModel()
- {
- ProductName = "三星智能手机",
- ProductBrand = "三星",
- ProductPrice = 3800,
- Quantity = 3
- };
- ProductModel product3 = new ProductModel()
- {
- ProductName = "松下液晶电视机",
- ProductBrand = "松下",
- ProductPrice = 3800,
- Quantity = 2
- };
- productList.Add(product1);
- productList.Add(product2);
- productList.Add(product3);
- return productList;
- }
- /// <summary>
- /// 获取订单信息
- /// </summary>
- public OrderModel GetOrderInfo()
- {
- OrderModel order = new OrderModel() {
- OrderNo = "P20140929001",
- OrderTime = DateTime.Now,
- CustomName = "张三",
- CustomAddress = "广东省深圳市罗湖区",
- ProductList = GetProductList()
- };
- return order;
- }
3.3 视图
在Views视图目录中创建Index.cshtml
- <h2>使用NPOI生成Excel文件</h2>
- <a href="@Url.Action("ExportProduct","Export")">导出商品</a>
- <a href="@Url.Action("ExportOrder","Export")">导出订单</a>
