Question

我试图把这个从我的控制器传到我的视野(7Captail ):

ViewBag.Chapter7Total = calc.CalculatePrice(quoteData, Chapter7);

但正在获取 VS 中的“ 在当前上下文错误中存在 ” 。

基本上,我正试图通过第二个参数,该参数确定2章第7章或第13章之间的定价结构,选择后确定第二个参数来进行计算。

以下是我的方法:

class Chapter
{
    public decimal PaymentPlan { get; set; }
    public decimal Price { get; set; }
}

public decimal decPaymentPlan(QuoteData quoteData, Chapter chapter)
{
    if (quoteData.StepFilingInformation.PaymentPlanRadioButton 
        == StepFilingInformation.PaymentPlan.No)
        return PriceQuote.priceNoPaymentPlan;
    else
        return chapter.PaymentPlan;
}

public decimal Calculate(QuoteData quoteData, Chapter chapter)
{
    decimal total = chapter.Price;
    total += this.decPaymentPlan(quoteData, chapter);

    return total;
}

static Chapter Chapter7 = new Chapter() { Price = 799.00m, PaymentPlan = 100.00m };

最后,这是我的控制器:

public ActionResult EMailQuote()
{
    Calculations calc = new Calculations();
    Chapter chap = new Chapter();

    QuoteData quoteData = new QuoteData
    {
        StepFilingInformation = new Models.StepFilingInformation
        {
            //just moking user input here temporarily to test out the UI
            PaymentPlanRadioButton = Models.StepFilingInformation.PaymentPlan.Yes,
        }
     };

     var total = calc.CalculatePrice(quoteData);
     ViewBag.Chapter7Total = calc.CalculatePrice(quoteData, Chapter7);
     return View(quoteData);
}

我不知道该怎么过7章有什么想法吗?

<强 > UPATE 1:

这是我的视图模式 ():

public class QuoteData
{
    public PriceQuote priceQuote;
    public Calculations calculations;
    public StepFilingInformation stepFilingInformation { get; set; }
    public QuoteData()
    {
        PriceQuote = new PriceQuote();
        Calculations = new Calculations();
    }
}

我试图弄清楚你在这里做什么,但我看到,最重要的是,你正在发送 qoteData 到您的视图中。我在这里猜测,但我发现 ooteData 是您的定制实体类型,而不是 ViewModel 。

首先,我要在您的模型中创建一个 ,该模型具有您需要的所有特性 ,包括

public class QuoteDataViewModel {
   ... all of your quoteData properties here
   public Chapter Chapter7 { get; set; }
}

在您 email iuote 动作中,类似此动作

public ActionResult EMailQuote() {
    ...
    var model = new QuoteDataViewModel();
    var quoteData = new QuoteData();
    ... // map your quoteData to your model with Automapper or manually like
    ... // model.SomeProperty = quoteData.SomeProperty;
    ... // repeat for all properties
    model.Chapter7 = Chapter7;
    return View(model);
}

如果您正在将此数据上传回, 您需要您的 Post 动作来接受新的。



public ActionResult EmailQuote(QuoteDataViewModel model) {
    if(ModelState.IsValid) {
        ....//save data that was entered?
    }
    return View(model);
}


您的视图将使用引号DateView 模式

@model QuoteDataViewModel


我完全不明白你到底在说什么, 比如说,这条线:

var total = calc.CalculatePrice(quoteData);

我看不出在您创建后曾经使用过 commed community 。

总之, 仅此样板, 我如何做它, 创建一个特定视图的模型, 包括任何和所有我需要的属性, 在控制器中填入模型, 并将其发送到视图中。

Update

根据OP的评论,引用Data是视图模式,然后和上文一样,添加新属性以持有额外数据很简单,因为添加...

public decimal QuoteTotal { get; set; }
public Chapter Chapter7 { get; set; }

... 查看模式

控制器弹出

var total = calc.CalculatePrice(quoteData);
model.QuoteTotal = total;
model.Chapter7 = new Chapter();
model.Chapter7 = Chapter7;

在“视图”中,可以访问以下值:

@Html.DisplayFor(model => model.QuoteTotal)
@Html.DisplayFor(model => model.Chapter7.PaymentPlan)
@Html.DisplayFor(model => model.Chapter7.Price)
