使用MVC controller输出excel的例子,自不待言,例子满天飞。
由于本项目使用的是Asp.net MVC API,因此在本项目使用API,实现了文件下载功能。代码的原理很简单,基本上是老外的代码。只是修改了一部分,以使其代码能正常工作(原代码输出的excel是空的)。以下是核心代码:
HSSFWorkbook workbook = new HSSFWorkbook(); ISheet sheet = workbook.CreateSheet("sheet1"); IRow row = sheet.CreateRow(0); row.CreateCell(0).SetCellValue("教师姓名"); row.CreateCell(1).SetCellValue("学校"); row.CreateCell(2).SetCellValue("年级平均分"); row.CreateCell(3).SetCellValue("年级最高分"); row.CreateCell(4).SetCellValue("年级最低分"); row.CreateCell(5).SetCellValue("全市所处名次"); sheet.SetColumnWidth(1, 5000); sheet.SetColumnWidth(2, 5000); sheet.SetColumnWidth(3, 5000); sheet.SetColumnWidth(4, 5000); sheet.SetColumnWidth(5, 5000); for (var i = 0; i < list.Count; i++) { IRow row1 = sheet.CreateRow(i + 1); row1.CreateCell(0).SetCellValue(list[i].XM); row1.CreateCell(1).SetCellValue(list[i].XXMC); row1.CreateCell(2).SetCellValue(list[i].AVGScore.ToFloat()); row1.CreateCell(3).SetCellValue(list[i].MaxScore.ToFloat()); row1.CreateCell(4).SetCellValue(list[i].MinScore.ToFloat()); row1.CreateCell(5).SetCellValue(list[i].OrderNumber); } System.IO.MemoryStream ms = new System.IO.MemoryStream(); workbook.Write(ms); ms.Position = 0; var response = new HttpResponseMessage(HttpStatusCode.OK); response.Content = new StreamContent(ms); response.Content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream"); var fileName = "教学排名_" + (Courselist == null || courseID == null ? "全部" : Courselist.Name) + ".xls";
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment") { FileName = System.Web.HttpUtility.UrlEncode(fileName) }; return response;
代码不难理解,自己琢磨下即可。记录下来,以备后用。
