5 在HomeController中添加NPOI的引用，再添加一个Export方法，构造一个list数据，并使用NPOI组件将数据导出到excel，详细代码参见截图 6 在Index页面添加一个【导出Excel】按钮，并将导出按钮包含在form标签中，form标签指向HomeController中的export方法 7 在VS中按F5调试模式运行页面，效果如下 ...
NPOI List导入Excel publicstaticboolExportE<T>(stringoutput,stringfileName, List<T> datalist, Dictionary<string,string> name)whereT :class{try{if(datalist.Count <=0) {returnfalse; }//HSSFWorkbook => xls//XSSFWorkbook => xlsxIWorkbook workbook;stringfileExt = Path.GetExtension(fileName).ToLowe...

首先NuGet引入NPOI和Npoi.Mapper 增加一个ExcelHelper public class ExcelHelper { /// /// List转Excel /// /// <typeparam name="T"></typeparam> /// 数据 /// 表名 /// true,覆盖单元格,false追加内容(list和创建的excel或excel模板) /// true-xlsx,false-xls /// <returns>返回文件</retu...
();for(inti=1;i<=10;i++){Useruser=newUser(){UserId=i,UserName="用户"+i,Phone="13800000000",Email=$"user{i}@qq.com"};usrs.Add(user);}//List转为Excel文件varfileStream=ExcelHelper.ParseListToExcel(usrs);returnFile(fileStream.ToArray(),"application/vnd.ms-excel","用户信息.xlsx")...
publicstaticMemoryStreamDataTableToExcel(List<OffLineOrderListModel>offLineOrderListModelList,stringstrHeaderText) { HSSFWorkbookworkbook=newHSSFWorkbook(); HSSFSheetsheet=(HSSFSheet)workbook.CreateSheet(); //excel总共有11列 string[]columnarr=newstring[] ...
DataSet result= ConvertToDataSet<UnitPrn>(list);vart = result.Tables[0];//生成ExcelStatus.Text ="导出文件中...";if(DataTableToExcel(t,"Bldg",true, foldPath)) Status.Text="成功导出文件!";else{return; } 1. 2. 3. 4. 5. 6
组成数据集合(List或DataTable) 创建sheet 设置相关样式等等 遍历赋值row 导出文件流 了解完,我们就继续来搞吧。 /// /// 导出Excel文件/// /// <typeparam name="T">数据类型</typeparam>/// 数据实体/// 列对应关系,如Name->姓名/// 标题/// <returns></returns>publicstaticbyte[]ExportExcel<T>(...
PageList<FairBatchOrderNo> list = orderBll.GetFairServiceOrderNoListToExcel(pageIndex, pageSize, batchID, postersState, companyID, companyName, creator, auditor, beginDate, endDate, beginCreateDate, endCreateDate, beginAuditDate, endAuditDate, needProcess, fairServiceBatchState, needPrint); try ...
