Question

我在创建通用视图以表示NotFound页面时遇到问题。

视图已创建且没问题。我需要知道如何将用户引导到控制器中的NotFound视图以及如何在每个控制器中呈现特定的“返回索引”。

以下是一些代码：

public class NotFoundModel
{
    private string _contentName;
    private string _notFoundTitle;
    private string _apologiesMessage;

    public string ContentName { get; private set; }
    public string NotFoundTitle { get; private set; }
    public string ApologiesMessage { get; private set; }

    public NotFoundModel(string contentName, string notFoundTitle, string apologiesMessage)
    {
        this._contentName = contentName;
        this._notFoundTitle = notFoundTitle;
        this._apologiesMessage = apologiesMessage;
    }

    }

// NotFound View

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Geographika.Models.NotFoundModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    <%= Html.Encode(Model.ContentName) %>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2><%= Html.Encode(Model.NotFoundTitle) %></h2>

    <p><%= Html.Encode(Model.ApologiesMessage) %></p>

    <!-- How can i render here a specific "BackToIndexView", but that it's not bound to
    my NotFoundModel? -->

</asp:Content>

//控制器代码

    //
    // GET: /Term/Details/2
    public ActionResult Details(int id)
    {
        Term term = termRepository.SingleOrDefault(t => t.TermId == id);

        if (term == null)
            return View("NotFound"); // how can i return the specific view that its not bound to Term Model?

            // the idea here would be something like:
            // return View("NotFound",new NotFoundModel("a","b","c"));

        else
            return View("Details", term);
    }

我不确定如何重定向到整个不同的页面。任何人都可以给我任何指示吗？

很简单，这是我使用的，并且几乎没有依赖。

在控制器中创建一个ErrorController.cs：

public class ErrorController : Controller
    {
        public ErrorController()
        {
            //_logger = logger; // log here if you had a logger!
        }

        /// <summary>
        /// This is fired when the site gets a bad URL
        /// </summary>
        /// <returns></returns>
        public ActionResult NotFound()
        {
            // log here, perhaps you want to know when a user reaches a 404?
            return View();
        }
    }
}

然后只需创建一个包含以下内容的Views\Error\NotFound.aspx，根据您的需要进行调整（包括“返回主页”链接，我将为您提供默认选项）：

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Oops - No content here!
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>404 Error - Can't find that page</h2>

    <p>Sorry, we cannot find the page you are looking for</p>

</asp:Content>

然后只需在<system.web>标签中的MVC应用Web.config中：

<customErrors mode="Off" defaultRedirect="/error/problem">
    <error statusCode="404" redirect="/error/notfound"/>
</customErrors>

如果您使用标准的全能路线，则无需自定义路线。希望有所帮助。

感谢您的投入。在这里努力思考，我设法创建了一个单一的NotFound视图和这样的模型：

public class NotFoundModel
{
    private string _contentName;
    private string _notFoundTitle;
    private string _apologiesMessage;
    private string _linkText;
    private string _action;
    private string _controller;

    // properties omitted for brevity;

    public NotFoundModel(string contentName, string notFoundTitle, string apologiesMessage,
        string linkText, string action, string controller)
    {
        this._contentName = contentName;
        this._notFoundTitle = notFoundTitle;
        this._apologiesMessage = apologiesMessage;
        this._linkText = linkText;
        this._action = action;
        this._controller = controller;
    }

    }

我的观点

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Geographika.Models.NotFoundModel>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    <%= Html.Encode(Model.ContentName) %>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2><%= Html.Encode(Model.NotFoundTitle) %></h2>

    <p><%= Html.Encode(Model.ApologiesMessage) %></p>

    <%= Html.ActionLink(Model.LinkText,Model.Action,Model.Controller) %>

</asp:Content>

这是我如何使用它的一个例子：

    public ActionResult Delete(int id)
    {
        Term term = termRepository.SingleOrDefault(t => t.TermId == id);

        if (term == null)
            return View("NotFound", new NotFoundModel("Termo não encontrado", "Termo não encontrado",
            "Nos desculpe, mas não conseguimos encontrar o termo solicitado.", "Indíce de Termos", "Index", "Term"));
        else
            return View("Delete");
    }

不知何故，ASP.MVC也搜索共享文件夹中的所有NotFound视图，因此作为唯一的视图，它会使用指向相应“转到模型索引”链接的链接呈现此视图。

感谢您的帮助。
