C# 使用Aspose.Cells 导出Excel

本文主要是介绍C# 使用Aspose.Cells 导出Excel，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

今天在工作中碰到同事用了一种新型的方式导入excel，在此做个学习记录。

插件：Aspose.Cells

第一步:准备好导出的模板，例子：

C#代码：

#region 验证数据

            if (model == null)
            {
                throw new FriendlyException("无该月结单！");
            }
            var templatePath = @"Template\trade\Cecsc2bHN\分包分供月度结算审批表.xlsx"; ;
            var resFileName = string.Empty;
            var bigTitle = string.Empty;
            var barCodeStr = string.Empty;


            if (string.IsNullOrEmpty(templatePath) || !File.Exists(templatePath))
            {
                throw new FriendlyException("未找到模板文件！");
            }

            #endregion

            #region 初始化模板文件

            var wk = new Workbook(templatePath);
            var designer = new WorkbookDesigner(wk);

            #endregion

            #region 数据重构造

            // 工程形象进度

            #endregion

            #region 构造头部信息
            var topInfo = new Dictionary<string, object>
            {

                { "Code", barCodeStr }
            };
            #endregion

            MonthSettlementInfo monthInfo = new MonthSettlementInfo()
            {

                CurrentInContractSafeAmount = 2.32M,
                TerminalInContractSafeAmount = 1.32M,
                CurrentOutContractSafeAmount = 6.32M,
                TerminalOutContractSafeAmount = 8.32M,
                CurrentDeductionSafeAmount = 4.32M,
                TerminalDeductionSafeAmount = 3.32M, 
            };

 

            //形象进度描述
            List<TradeSettleReportProjectProgressItemModel> ProjectProgressList = new List<TradeSettleReportProjectProgressItemModel>();

            for (int i = 0; i < 3; i++)
            {

                    ConstractSite = "场地" + i
                };
                ProjectProgressList.Add(Progressmodel);
            }

            #region 工程名称
  
            //绑定数据到excel中
            //designer.SetDataSource("绑定的到excle的变量名"，"对应的值")
            designer.SetDataSource("ProgressItem", ProjectProgressList);    //list可以循环绑定  绑定的例子在下面。

            #endregion

            #region 重新计算行高
            var startRow = 9;
            var endRow = startRow;

            #endregion

            #region 导出文件

            var fileName = $"{model.SettlementMonth.ToString("yyyy年MM月")}{resFileName}.xlsx";
            using (var file = new MemoryStream())
            {
                wk.Save(file, SaveFormat.Xlsx);
                wk.Dispose();
                return new KeyValuePair<string, byte[]>(fileName, file.ToArray());
            }
            #endregion

此种当时的重点是Excel模板的数据绑定：

第一种：单个值的绑定

第二种：列表值的循环绑定
