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。
Aspose.Cells简介：Aspose.Cells是一款功能强大的Excel文档处理和转换控件，开发人员和客户电脑无需安装Microsoft Excel也能在应用程序中实现类似Excel的强大数据管理功能，支持所有Excel格式类型的操作，在没有Microsoft Excel的环境下，用户也可为其应用程序嵌入类似Excel的强大数据管理功能。
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);
#region 数据重构造
// 工程形象进度
#region 构造头部信息
var topInfo = new Dictionary<string, object>
{ "Title", bigTitle },
{ "ProjectName", model.ProjectName },
{ "Code", barCodeStr }
};
MonthSettlementInfo monthInfo = new MonthSettlementInfo()
CurrentInContractSettlementAmount = 56.32M,
TerminalInContractSettlementAmount = 123.32M,
CurrentOutContractSettlementAmount = 6.32M,
TerminalOutContractSettlementAmount = 5.32M,
CurrentDeductionSettlementAmount = 12.32M,
TerminalDeductionSettlementAmount = 26.32M,
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++)
TradeSettleReportProjectProgressItemModel Progressmodel = new TradeSettleReportProjectProgressItemModel()
{
ConstractArea = "测试水水水水水水" + i,
Remark = "测试模拟的备注" + i,
ProgressDesc = "测试撒子怕发送所属" + 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。
designer.SetDataSource("ProjectName", model.ProjectName);
designer.SetDataSource("ContractName", model.ContractName);
designer.SetDataSource("ContractCode", model.ContractCode);
designer.SetDataSource("MonthSettlementNo", model.MonthSettlementNo);
designer.SetDataSource("ContractingUnit", model.ContractingUnit);
designer.SetDataSource("SettlementCode", model.SettlementCode);
designer.SetDataSource("EnterpriseName", model.EnterpriseName);
designer.SetDataSource("ThirdPartyName", model.ThirdPartyName);
designer.SetDataSource("SettlementMonth", model.SettlementMonth);
designer.SetDataSource("TotalContractAmount", model.TotalContractAmount);
designer.SetDataSource("SettlementAmountCapitalize", model.SettlementAmountCapitalize);
#region 尾部
#endregion
designer.Process();
wk.CalculateFormula();
#region 重新计算行高
var startRow = 9;
var endRow = startRow;
#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());
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
