ASP.NET MVC4找不到路徑“ / enquiry /”的控制器或未實現IController。 下拉列表返回錯誤

Question

當我導航到“查詢區域”時，我的應用程序將返回此值，當前我必須進入“工作區域”，“小冊子和查詢”，然后再進行第三個操作（付款），當我導航至“小冊子區域”時，不會顯示錯誤。

我試圖在引發錯誤的視圖中添加一個area參數，將字符串保留為空，並使用Inquiry，如下所示：

@Html.Action("DropDownList", "Enquiry Base", new { type = "titles", areas = ""})

@Html.Action("DropDownList", "Enquiry Base", new { type = "titles", areas = "Enquiry"})

這些都不解決了錯誤。

目前，為了顯示下拉列表，我在根目錄中有一個viewmodel，局部視圖和unity bootstrapper：

ItemsViewModel

public class DropDownListItem
{
    public string Text { get; set; }
    public string Value { get; set; }
}

public class ItemsViewModel
{
    private readonly List<DropDownListItem> _items;

    public string SelectedItem { get; set; }

    public IEnumerable<SelectListItem> Items
    {
        get
        {
            var allItems = _items.Select(i => new SelectListItem
                {
                    Value = i.Value,
                    Text = i.Text
                });
            return DefaultItem.Concat(allItems);
        }
    }

    public IEnumerable<SelectListItem> DefaultItem
    {
        get
        {
            return Enumerable.Repeat(new SelectListItem
                {
                    Value = "",
                    Text = Mui.please_select
                }, count: 1);
        }
    }

    public ItemsViewModel()
    {

    }

    public ItemsViewModel(List<DropDownListItem> items, string selected)
    {
        _items = items;
        SelectedItem = selected;
    }

DropDownPartial

@using MBS.Exec.Mvc.ViewModels
@model ItemsViewModel

@Html.DropDownListFor(m => m.SelectedItem, Model.Items)

引導程序

public static class Bootstrapper
{
    public static void Initialise()
    {
        var container = BuildUnityContainer();

        DependencyResolver.SetResolver(new UnityDependencyResolver(container));

        GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container);
    }

    private static IUnityContainer BuildUnityContainer()
    {
        var container = new UnityContainer();

        container.RegisterType<IBrochureModel, MilitaryBrochureViewModel>();
        container.RegisterType<IBrochureModel, GeneralBrochureViewModel>();
        container.RegisterType<IBrochureModel, StandardBrochureViewModel>();
        container.RegisterType<IBrochureModel, StudentBrochureViewModel>();

        container.RegisterType<IEnquiryModel, MilitaryEnquiryViewModel>();
        container.RegisterType<IEnquiryModel, GeneralEnquiryViewModel>();
        container.RegisterType<IEnquiryModel, StandardEnquiryViewModel>();
        container.RegisterType<IEnquiryModel, StudentEnquiryViewModel>();

        container.RegisterType<IFormData, FormData>();
        container.RegisterType<IRESTExecutiveService, RESTExecutiveService>();

        return container;
    }

為了使用該區域中的下拉菜單，我在EnquiryBaseController中創建了一個DropDownList ActionResult：

[ChildActionOnly]
    public ActionResult DropDownList(string type, string selected)
    {
        if (type == "titles")
        {
            var items = new ItemsViewModel(
                (from g in _service.GetTitles() select new DropDownListItem { Text = g.Value, Value = g.Value }).ToList(),
                selected);

            return PartialView("DropDownPartial", items);
        }
        else if (type == "leadSources")
        {
            var items = new ItemsViewModel(
                (from g in _service.GetLeadSources() select new DropDownListItem { Text = g.Value, Value = g.Value }).ToList(),
                selected);

            return PartialView("DropDownPartial", items);
        }

        return null;
    }

然后，我使用上面的@ Html.Action代碼在視圖上呈現下拉列表。

有誰知道為什么會引發此錯誤？

Answer 1

你打電話時

@Html.Action("DropDownList", "Enquiry Base", new { type = "titles", areas = ""}) 

控制器名稱字符串中有一個空格。

嘗試這個：

@Html.Action("DropDownList", "EnquiryBase", new { type = "titles", areas = ""})

我猜想錯誤發生的原因是“ / enquiry /”，因為它只讀取字符串的第一部分。
