C# 在ASP.MVC中创建通用NotFound视图

我在创建表示未找到页面的通用视图时遇到问题

视图已创建，一切正常。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”

下面是一些代码：

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;
    }

    }

//未找到视图

<%@ 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>

我不知道如何重定向到一个完全不同的页面。有人能给我指点吗

谢谢你的意见。在这里仔细思考，我成功地创建了一个NotFound视图和模型，如下所示：

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;
    }

    }

我的看法

<%@ 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>

不知何故，ASP.MVC也搜索了共享文件夹中所有未找到的视图，因此它是唯一的一个视图，它使用指向适当“转到模型索引”链接的链接呈现此视图

感谢所有的帮助。

非常简单，这就是我使用的，并且没有太多依赖性

在控制器中创建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();
        }
    }
}

然后只需在MVC应用程序Web.config中的

标记中：

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

如果使用标准的“全部捕获”路线，也不需要自定义路线。希望有帮助

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();
        }
    }
}

<%@ 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>

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