ASP.net MVC 5 C#从IF语句中返回double

如何从IF语句中访问double

 [HttpPost]
    public ActionResult Iflexcst([Optional] float Quan, [Optional] float kammid, [Optional] float kammod, [Optional] float SpacerInnerDim, [Optional] float SpacerOuterDim, [Optional] float WashOuterDim, [Optional]float IsoWashInnerDim, [Optional]float SteelWashInnerDim, [Optional] float SteelWashQuan, [Optional] float IsoWashQuan, FormCollection form)
    {
        //other functions removed
        if (WashOuterDim <= 43.6)
        {

            double washerSerrTime = 0.6;
            double SerrWasherRun = (washerSerrTime * IsoWashQuan) * (1 / 60);
            ViewBag.SerrWasherRun = SerrWasherRun;

            double SerrWasherRunPrice = ((SerrateSetup / Quan) + washerSerrTime) * serrateRate;
            ViewBag.SerrWasherRunPrice = SerrWasherRunPrice;

        }

        if (WashOuterDim > 43.6)
        {


            double washerSerrTime = 0.833;
            double SerrWasherRun = (washerSerrTime * IsoWashQuan) * (1 / 60);
            ViewBag.SerrWasherRun = SerrWasherRun;

            double SerrWasherRunPrice = ((SerrateSetup / Quan) + washerSerrTime) * serrateRate;
            ViewBag.SerrWasherRunPrice = SerrWasherRunPrice;


        }


        // Adds together all costs 
        float Price = (float)SerrWasherRunPrice;

它建议为“SerrWasherRunPrice”创建获取和设置，或将其作为公共变量，但这两种解决方案都会与另一个声明冲突。

如果

        double washerSerrTime = 0.6;
        double SerrWasherRun = (washerSerrTime * IsoWashQuan) * (1 / 60);
        ViewBag.SerrWasherRun = SerrWasherRun;

双倍价格=0；
如果（WashOuterDim，因为您总是将其存储在
ViewBag
上，因此您不必对代码进行太多更改

// Adds together all costs 
float Price = (float)ViewBag.SerrWasherRunPrice;

我正是这样做的，它给了我错误1一个名为“SerrWasherRunPrice”的局部变量不能在这个范围内声明，因为它会给“SerrWasherRunPrice”一个不同的含义，它已经在“父或当前”范围内用于表示其他内容
