show your code:
- public ActionResult OutPutExcel()
- {
- //在内存中构建一个excel
- HSSFWorkbook workbook = new HSSFWorkbook();
-
- //在创建一个excel的表
- HSSFSheet sheet = workbook.CreateSheet("学生信息表") as HSSFSheet;
-
- //创建行
- HSSFRow row = sheet.CreateRow(0) as HSSFRow;
-
- //创建列(填充数据)
- row.CreateCell(0).SetCellValue("用户名");
-
- HSSFCell cell = row.CreateCell(1) as HSSFCell;
- cell.SetCellValue("学号");
- row.CreateCell(2).SetCellValue("年龄");
- row.CreateCell(3).SetCellValue("班级");
-
- //合并单元格(合并第一行的第1列到第3列)
- sheet.AddMergedRegion(new NPOI.SS.Util.CellRangeAddress(0, 0, 1, 3));
- //合并单元格(合并行,合并第一行的第2到4列)
- sheet.AddMergedRegion(new NPOI.SS.Util.CellRangeAddress(2, 4, 0, 0));
-
- //创建一个样式类
- HSSFCellStyle cellstyle = workbook.CreateCellStyle() as HSSFCellStyle;
- //水平居中
- cellstyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.CENTER;
- //垂直居中
- cellstyle.VerticalAlignment = NPOI.SS.UserModel.VerticalAlignment.CENTER;
-
- cell.CellStyle = cellstyle;
-
-
- //把内存流做为文件下载中转
- MemoryStream memoryStream = new MemoryStream();
- workbook.Write(memoryStream);
-
- Response.AddHeader("Content-Disposition", "attachment; filename=学生信息表.xls");
-
- Response.BinaryWrite(memoryStream.ToArray());
-
- return View();
- }
根据模板导出,还有添加样式等
- public ActionResult OutPutExcel()
- {
- //在内存中构建一个excel
- HSSFWorkbook workbook = new HSSFWorkbook();
-
- //在创建一个excel的表
- HSSFSheet sheet = workbook.CreateSheet("学生信息表") as HSSFSheet;
-
-
- //创建行
- HSSFRow headerrow = sheet.CreateRow(0) as HSSFRow;
- //设置行高
- headerrow.Height = 1200;
-
-
- for (int i = 0; i < 3; i++)
- {
- sheet.SetColumnWidth(i, 220 * 25);
- }
-
- HSSFCell headcell = headerrow.CreateCell(0) as HSSFCell;
- headcell.SetCellValue("重庆优质学生信息公示\nQQ:48672901");
-
- //头部样式
- HSSFCellStyle headCellStyle = workbook.CreateCellStyle() as HSSFCellStyle;
- headCellStyle.VerticalAlignment = NPOI.SS.UserModel.VerticalAlignment.CENTER;
- headCellStyle.Alignment = NPOI.SS.UserModel.HorizontalAlignment.CENTER;
- headCellStyle.WrapText = true;
-
- //设置字体样式
- HSSFFont font = workbook.CreateFont() as HSSFFont;
- font.Boldweight = 800;
- font.FontHeight = 350;
- font.Color = HSSFColor.RED.index;
- font.FontName = "微软雅黑";
-
- headCellStyle.SetFont(font);
- headcell.CellStyle = headCellStyle;
-
- //创建行
- HSSFRow row = sheet.CreateRow(1) as HSSFRow;
-
- //创建列(填充数据)
- row.CreateCell(0).SetCellValue("用户名");
-
- HSSFCell cell = row.CreateCell(1) as HSSFCell;
- cell.SetCellValue("学号");

- sheet.AddMergedRegion(new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 3));
- //合并单元格(合并行,合并第一行的第2到4列)
- //sheet.AddMergedRegion(new NPOI.SS.Util.CellRangeAddress(2, 4, 0, 0));
-
- //创建一个样式类
- HSSFCellStyle cellstyle = workbook.CreateCellStyle() as HSSFCellStyle;

- workbook.Write(memoryStream);
-
- Response.AddHeader("Content-Disposition", "attachment; filename=学生信息表.xls");
-
- Response.BinaryWrite(memoryStream.ToArray());
-
- return View();
- }
-
- /// <summary>

- public void OutPutExcelByTemp()
- {
- string url = Server.MapPath("~/excel/temp.xls");
-
- FileStream filestream = new FileStream(url, FileMode.Open);
-
- //根据文件流加载excel
- HSSFWorkbook workbook = new HSSFWorkbook(filestream);
-
- //获取表
- HSSFSheet sheet = workbook.GetSheet("2021年度财务报表") as HSSFSheet;
-
-
- for (int i = 3; i < 10; i++)
- {
- HSSFRow row = sheet.CreateRow(i) as HSSFRow;
- row.Height = 700;
-
- for (int j = 0; j < 8; j++)

-
- cell.SetCellValue("富婆" + i * j);
-
- cell.CellStyle = cellstyle;
- }
- }
-

- //把内存流做为文件下载中转
- MemoryStream memoryStream = new MemoryStream();
- workbook.Write(memoryStream);

- Response.BinaryWrite(memoryStream.ToArray());
- }
