我试图将这个从我的控制器传递到我的视图(@ViewBag.Chapter7Total
):
ViewBag.Chapter7Total = calc.CalculatePrice(quoteData, Chapter7);
但是在VS.
中得到“当前上下文错误中不存在”基本上,我试图传递第二个参数,该参数确定在2. Chapter7或Chapter13之间使用哪个定价结构,选择确定第二个参数来执行计算。
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);
}
我不知道如何通过第7章。有什么想法吗?
更新1:
这是我的ViewModel(QuoteData
):
public class QuoteData
{
public PriceQuote priceQuote;
public Calculations calculations;
public StepFilingInformation stepFilingInformation { get; set; }
public QuoteData()
{
PriceQuote = new PriceQuote();
Calculations = new Calculations();
}
}
答案 0 :(得分:1)
我正在试图弄清楚你在这里做了什么,但我发现最重要的是,你正在向你的视图发送quoteData
。我在这里猜测,但我认为QuoteData
是您的自定义实体类型,而不是ViewModel
。
首先,我会在您的模型中创建一个QuoteDataViewModel
,其中包含您需要的所有QuoteData
属性,包括
public class QuoteDataViewModel {
... all of your quoteData properties here
public Chapter Chapter7 { get; set; }
}
在EMailQuote
行动中,类似于此
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);
}
如果您要发回此数据,则需要Post
行动才能接受新的QuoteDataViewModel
public ActionResult EmailQuote(QuoteDataViewModel model) {
if(ModelState.IsValid) {
....//save data that was entered?
}
return View(model);
}
您的视图将采用QuoteDateViewModel
@model QuoteDataViewModel
这就是我个人的表现,我不太了解你的情况,例如,这一行:
var total = calc.CalculatePrice(quoteData);
创建后我没有看到total
被使用过。
无论如何,这只是我如何做的一个示例,创建一个特定于视图的模型,包括我需要的任何和所有属性,在控制器中填充模型并将其发送到视图
根据OP注释,quoteData是一个ViewModel,如上所述,通过添加...来添加新属性以保存额外数据很简单...
public decimal QuoteTotal { get; set; }
public Chapter Chapter7 { get; set; }
...到ViewModel
控制器填充
var total = calc.CalculatePrice(quoteData);
model.QuoteTotal = total;
model.Chapter7 = new Chapter();
model.Chapter7 = Chapter7;
在视图中,可以访问值:
@Html.DisplayFor(model => model.QuoteTotal)
@Html.DisplayFor(model => model.Chapter7.PaymentPlan)
@Html.DisplayFor(model => model.Chapter7.Price)
