问：

PDF 数据不会根据插入的数据动态变化

**我有一个应用程序，其中的模型、控制器、接口和管理器类都是 C# 的，也许从您可以理解的代码和图像中我需要更新总公积金第 80C 节的数据** `

 public class EmplyeeSalaryDetails
 {

     public EmplyeeSalaryDetails()
     {
         SectionInvestmentList = new List<KeyValue>();
     }
     public string EmployeeId { get; set; }
     public string EmployeeName { get; set; }
     public decimal Amount { get; set; }
     public decimal PaidAmount { get; set; }
     public decimal EPFAmount { get; set; }
     public decimal EmployeeInvestmentsAmount { get; set; }

     public decimal TotalConveyanceAndHouseRent { get; set; }

     public decimal DeductedConvAndHouseAMtInPaidAmt { get; set; }

 public ActionResult DownloadEmployeeForm16(string Id, string cookieValue = "")
 {
     EmplyeeSalaryDetails empSalaryDetail = new EmplyeeSalaryDetails();

     try
     {
         Guid empId = new Guid(Id);
         empSalaryDetail = _paySalaryManager.GetEmployeeSalary(empId);
         if (empSalaryDetail.PaidAmount > 0)
         {
             return FileAsPDF(empSalaryDetail, "Partials/_EmployeeForm16", "Form16_" + DateTime.Now.ToShortDateString(), cookieValue);
         }
     }
     catch (Exception ex)
     {
         Elmah.ErrorSignal.FromCurrentContext().Raise(ex);
         TempData["Success"] = "Something went wrong";
     }

     return RedirectToAction("EmployeeInvestmentDetailList");
     //return FileAsPDF(empSalaryDetail, "Partials/_EmployeeForm16", "Form16_" + DateTime.Now.ToShortDateString(), cookieValue); 
 }

 var empInvestmentData = context.EmployeeInvestmentDetails.Where(x => !x.IsDeleted && x.EmployeeId == Id);
 empSalaryDetail.PaidAmount = entity.Sum(x => x.PaidValue);
 empSalaryDetail.EPFAmount = entity.Sum(x => x.PaidValue );

查看 80C SEE 金额

我尝试了empSalaryDetail.EPFAmount = entity。Sum（x => x.PaidValue - x.EPF.toDecimal（） ）; 但是在此之后，它的投掷错误出了点问题 我期待总支付金额 - 我插入的 UI 中的总金额
