Asp.net mvc 3 MVC3-不是控制器中方法的渲染视图

我不知道如何最好地描述我的需求，但我还是这样说。我正在尝试从应用程序中的以下控制器/模型渲染视图：

CustomerController.cs代码段：

[NonAction]
protected CustomerNavigationModel GetCustomerNavigationModel(Customer customer)
{
   var model = new CustomerNavigationModel();
   model.HideAvatar = !_customerSettings.AllowCustomersToUploadAvatars;
   model.HideRewardPoints = !_rewardPointsSettings.Enabled;
   model.HideForumSubscriptions = !_forumSettings.ForumsEnabled || !_forumSettings.AllowCustomersToManageSubscriptions;
   model.HideReturnRequests = !_orderSettings.ReturnRequestsEnabled || _orderService.SearchReturnRequests(customer.Id, 0, null).Count == 0;
   model.HideDownloadableProducts = _customerSettings.HideDownloadableProductsTab;
   model.HideBackInStockSubscriptions = _customerSettings.HideBackInStockSubscriptionsTab;
   return model;
}

CustomerNavigationModel.cs：

public partial class CustomerNavigationModel : BaseNopModel
{
    public bool HideInfo { get; set; }
    public bool HideAddresses { get; set; }
    public bool HideOrders { get; set; }
    public bool HideBackInStockSubscriptions { get; set; }
    public bool HideReturnRequests { get; set; }
    public bool HideDownloadableProducts { get; set; }
    public bool HideRewardPoints { get; set; }
    public bool HideChangePassword { get; set; }
    public bool HideAvatar { get; set; }
    public bool HideForumSubscriptions { get; set; }

    public CustomerNavigationEnum SelectedTab { get; set; }
 }

public enum CustomerNavigationEnum
{
    Info,
    Addresses,
    Orders,
    BackInStockSubscriptions,
    ReturnRequests,
    DownloadableProducts,
    RewardPoints,
    ChangePassword,
    Avatar,
    ForumSubscriptions
}

MyAccountNavigation.cshtml代码段：

 @model CustomerNavigationModel
 @using Nop.Web.Models.Customer;
 @if (!Model.HideInfo)
 {
      <li><a href="@Url.RouteUrl("CustomerInfo")" class="@if (Model.SelectedTab == CustomerNavigationEnum.Info)
          {<text>active</text>}
          else
          {<text>inactive</text>}">@T("Account.CustomerInfo")</a></li>}

@model CustomerNavigationModel
@使用Nop.Web.Models.Customer；
@如果（！Model.HideInfo）
{
}

观点： @Html.Partial（“MyAccountNavigation”，Model.NavigationModel，new ViewDataDictionary（））

我知道它无法呈现MyAccountNavigation，因为它在控制器中不存在。但是，取决于语法所在的页面，它可以工作。那么，有没有一种方法可以在不改变控制器代码的情况下实现这一点？提前感谢。

我从您的问题中了解到，您需要从多个页面执行“MyAccountNavigation”部分视图，为此，您可以将此部分视图放在共享文件夹中

如果我错了，请纠正我

基本控制器：

例外核心法

您可以将菜单或该型号存储在ViewBag中，如

var customerNavigationModel = assigned your value;
ViewBag.MenuData = customerNavigationModel;

从视野

@{Html.RenderPartial("MyAccountNavigation", ViewBag.MenuData);}

---

MVC按特定顺序查找局部视图。要使部分视图正常工作，您需要将

MyAccountNavigation.cshtml'放入

~/Views/Shared中/`

我查看了来源，结果如下：

 public RazorViewEngine(IViewPageActivator viewPageActivator)
            : base(viewPageActivator)
        {
            AreaViewLocationFormats = new[]
            {
                "~/Areas/{2}/Views/{1}/{0}.cshtml",
                "~/Areas/{2}/Views/{1}/{0}.vbhtml",
                "~/Areas/{2}/Views/Shared/{0}.cshtml",
                "~/Areas/{2}/Views/Shared/{0}.vbhtml"
            };
            AreaMasterLocationFormats = new[]
            {
                "~/Areas/{2}/Views/{1}/{0}.cshtml",
                "~/Areas/{2}/Views/{1}/{0}.vbhtml",
                "~/Areas/{2}/Views/Shared/{0}.cshtml",
                "~/Areas/{2}/Views/Shared/{0}.vbhtml"
            };
            AreaPartialViewLocationFormats = new[]
            {
                "~/Areas/{2}/Views/{1}/{0}.cshtml",
                "~/Areas/{2}/Views/{1}/{0}.vbhtml",
                "~/Areas/{2}/Views/Shared/{0}.cshtml",
                "~/Areas/{2}/Views/Shared/{0}.vbhtml"
            };

            ViewLocationFormats = new[]
            {
                "~/Views/{1}/{0}.cshtml",
                "~/Views/{1}/{0}.vbhtml",
                "~/Views/Shared/{0}.cshtml",
                "~/Views/Shared/{0}.vbhtml"
            };
            MasterLocationFormats = new[]
            {
                "~/Views/{1}/{0}.cshtml",
                "~/Views/{1}/{0}.vbhtml",
                "~/Views/Shared/{0}.cshtml",
                "~/Views/Shared/{0}.vbhtml"
            };
            PartialViewLocationFormats = new[]
            {
                "~/Views/{1}/{0}.cshtml",
                "~/Views/{1}/{0}.vbhtml",
                "~/Views/Shared/{0}.cshtml",
                "~/Views/Shared/{0}.vbhtml"
            };

            FileExtensions = new[]
            {
                "cshtml",
                "vbhtml",
            };
        }

我们对

AreaPartialViewLocationFormats

和

PartialViewLocationFormats

感兴趣

这解释了为什么当您尝试在与客户相关的视图中使用视图时，会发现该视图，而在其他任何地方都不起作用。

您的局部视图位于何处？有效的视图，它们位于何处？不起作用的视图，它们位于哪里？部分视图文件是~/Views/Customer/MyAccountNavigation.cshtml，起作用的视图位于~/Views/Customer/文件夹中。如果我在~/Views/Shared/中的任何文件中插入“@Html.Partial（“MyAccountNavigation”，Model.NavigationModel，new ViewDataDictionary（）”），它将不起作用。我已将MyAccountNavigation.cshtml移动到共享文件夹中，并将语法更改为：@Html.Partial（“MyAccountNavigation”，new ViewDataDictionary（this.ViewData）），但返回错误：对象引用未设置为对象的实例。第18行：@if（！Model.HideInfo）。这是由于模型为空而产生的错误。您需要先检查模型！=空，然后检查HideInfo的值。如何从“受保护的CustomerNavigationModel GetCustomerNavigationModel（Customer）”查看模型？我尝试了“@Html.Partial（“~/Views/Customer/MyAccountNavigation.cshtml”，new Nop.Web.Models.Customer.CustomerNavigationModel（）”），但属性没有传递到模型中。我只想在可能的情况下更改视图中的语法。@scoo-b。我可以说，您希望在该部分视图中传递CustomerNavigationModel。为此，您需要将CustomerNavigationModel存储在控制器的ViewBag中，并从视图中获取相同的值。检查我编辑的代码。
