数据写入到Excel，模板样式复杂

先整理好Excel模板，如：

接下来在程序获取上面整理好的Excel模板并替换关键字就可以了public ActionResult SummaryStatistics()

public ActionResult SummaryStatistics()
{
　　　　　　　　Workbook workbook;
            using (var stream = System.IO.File.OpenRead(Server.MapPath("/Templates/Statistics/汇总表.xlsx")))
            {
                workbook = new Workbook(stream);
            }
            //上半部分统计
            workbook.Replace(string.Format("${0}$", "TrainOrgCount"), summaryLastMonth.TrainOrgCount);
            workbook.Replace(string.Format("${0}$", "TrainOrgThanLastMonth"), summaryLastMonth.TrainOrgThanLastMonth);
            workbook.Replace(string.Format("${0}$", "TrainCount"), summaryLastMonth.TrainCount);
            workbook.Replace(string.Format("${0}$", "TrainThanLastMonth"), summaryLastMonth.TrainThanLastMonth);
            workbook.Replace(string.Format("${0}$", "ExamCount"), summaryLastMonth.ExamCount);
            workbook.Replace(string.Format("${0}$", "PassRate"), summaryLastMonth.PassRate);
            workbook.Replace(string.Format("${0}$", "CertCount"), summaryLastMonth.CertCount);
            workbook.Replace(string.Format("${0}$", "CertThanLastMonth"), summaryLastMonth.CertThanLastMonth);
            workbook.Replace(string.Format("${0}$", "ContinueEduCount"), summaryLastMonth.ContinueEduCount);
            workbook.Replace(string.Format("${0}$", "ChangeCertCount"), summaryLastMonth.ChangeCertCount);
　　　　　　　//省略N个处理......，处理方式与上面一样
if (!System.IO.Directory.Exists(Server.MapPath("/UploadFileXLS")))
            {
                System.IO.Directory.CreateDirectory(Server.MapPath("/UploadFileXLS"));
            }
            var filePath = "/UploadXLS/" + time.AddMonths(-1).Year + "年" + time.AddMonths(-1).Month + "月份汇总表.xlsx";
            var address = Server.MapPath(filePath);
            if (System.IO.File.Exists(address))
            {
                System.IO.File.Delete(address);
            }
            workbook.Save(address);
　　　　　　　　return View();
}

 这样就处理好了
