当我导航到查询区域时，我的应用程序正在返回这个，我目前必须到工作区域、宣传册和查询以及第三个要遵循（支付），当我导航到宣传册区域时，不会显示错误。

我尝试在抛出错误的视图中添加一个区域参数，将字符串留空并使用查询，如下所示：

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

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

这些都没有解决错误。

目前为了显示下拉列表，我在根目录中有一个视图模型、部分视图和统一引导程序：

项目视图模型

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;
    }

下拉部分

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

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

引导程序

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;
    }

为了使用该区域的下拉菜单，我在 EnquiryBaseController 中创建了 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 代码在视图上呈现下拉菜单。

有谁知道为什么会抛出这个错误？

你打电话时

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

您在控制器名称字符串中有一个空格。

试试这个：

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

我认为错误出现'/enquiry/'的原因是因为它只读取字符串的第一部分。
