Question

考虑我的路线设置：

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "Question",
            url: "{number}",
            defaults: new { controller = "Home", action = "ViewQuestion" }
        );
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
            constraints: new { id = "\\d+" }
        );
    }

我想要的是：

1）如果网址为myserver/123，请拨打Home.ViewQuestion(string number)。

2）否则，使用Home/Index默认操作

搜索控制器和操作

我在申请myserver/123时获得的是：

The view '123' or its master was not found or no view engine supports the searched locations. The following locations were searched:
~/Views/Home/123.aspx
~/Views/Home/123.ascx
~/Views/Shared/123.aspx
~/Views/Shared/123.ascx
~/Views/Home/123.cshtml
~/Views/Home/123.vbhtml
~/Views/Shared/123.cshtml
~/Views/Shared/123.vbhtml

我的行动和观点：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace AdvancedWebApp.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult ViewQuestion(int? number)
        {
            return View(number + "");
        }

        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }
    }
}

ViewQuestion.cshtml：

@model string
@{
    ViewBag.Title = "ViewQuestion";
}

<h2>ViewQuestion: @Model</h2>

Answer 1

而不是网址：“{number}”，请使用网址：“ViewQuestion / {number}”和您的操作代码：

public ActionResult ViewQuestion(int? number)
    {
        //your code
    }

Answer 2

从您的控制器的操作中，您似乎将视图名称作为传递给它的号码返回。因此，当您将视图定义为ViewQuestion.cshtml时，MVC运行时正在寻找 123.html 或 123.aspx 。

public ActionResult ViewQuestion(int? number)
    {
        return View(number + "");
    }

您需要返回正确的视图名称，如下所示

public ActionResult ViewQuestion(int? number)
    {
        return View("ViewQuestion",number);
    }

Answer 3

原来我正在调用控制器辅助方法View(string viewName)，好像它是View(object model) !!!

    public ActionResult ViewQuestion(string questionNumber)
    {
        return View((object)questionNumber);
    }

没有控制器或动作的MVC路由
