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>
{
{ "Title", bigTitle },
{ "ProjectName", model.ProjectName },
{ "Code", barCodeStr }
};
#endregion 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);
#endregion #endregion #region 尾部 #endregion
designer.Process();
wk.CalculateFormula(); #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
