Sql server 基于两个表模型的MVC 4计算

使用MVC4，我从数据库中得到了两个相关的表（利率和支出）。 每次我在“PAYCHECK”表中创建一个事务时，我都希望它计算字段的总数：OrdinarySalary、OvertimeSalary、HolidaySalary等

我在PayCheckController中做了一些计算，但它只从表RATE返回一个主键（RateNumber）。它不返回其他字段，而是返回primarykey

这里有一个get方法

    // GET

    public ActionResult Create()
    {
        ViewBag.Employee_No = new SelectList(db.EMPLOYEEs, "Employee_No", "Employee_No");
        ViewBag.RateNumber = new SelectList(db.RATES, "RateNumber", "Description");
        return View();
    }

[HttpPost]
    public ActionResult Create(PAYOUT payout, RATE rate)
    {

        if (ModelState.IsValid)
        {  if (payout.RateNumber == rate.RateNumber)
            {

                payout.OrdinarySalary = Convert.ToInt32(payout.OrdinaryHours) * Convert.ToInt32(rate.Ord_Sal_rate);

                payout.OvertimeSalary = Convert.ToInt32(rate.Over_Sal_rate) * Convert.ToInt32(payout.OvertimeHours);

                payout.HolidaySalary = Convert.ToInt32(rate.Hol_Sal_rate) * Convert.ToInt32(payout.HolidayHours);

                payout.GrossWage = payout.OrdinarySalary+
                                   payout.OvertimeSalary +
                                   payout.HolidaySalary + 
                                   payout.BonusPay + 
                                   payout.ShiftAllowance;

                payout.ShiftAllowance = payout.GrossWage * 78 / 100;
            }
            db.PAYOUTs.Add(payout);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        ViewBag.Employee_No = new SelectList(db.EMPLOYEEs, "Employee_No", "Employee_No", payout.Employee_No);
        ViewBag.RateNumber = new SelectList(db.RATES, "RateNumber", "Description", payout.RateNumber);
        return View(payout);
    }

以下是观点：

我已经添加了这些行。。。而且似乎在工作

public ActionResult Create(PAYOUT payout, RATE ratenum)
    {


        var rate = db.RATES.First(m => m.RateNumber == ratenum.RateNumber);

---

您尚未显示相关代码-显示GET方法和view我已添加GET方法和view StephenYou没有为

Rate

的属性呈现任何表单控件（您也不应该，因为您只是选择了一个速率）。您需要根据所选ID再次从数据库中获取

速率

，并将其用于您的计算我已经让它工作了。。。谢谢：-）
