A.创建一个Basic类型的MVC项目.

B.在Content文件目录下创建下载文件资源:cs.rar,cs.doc,cs.txt等,见下图右方:

C.修改RouteConfig.cs文件:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Routing;namespace MvcRouteTest{    public class RouteConfig    {        public static void RegisterRoutes(RouteCollection routes)        {           routes.IgnoreRoute("{resource}.axd/{*pathInfo}");          routes.MapRoute(          name: "ForbidDownloadRar",          url: "Content/Download/a/b/c/{id}.rar",          defaults: new { controller = "Home", action = "ForbidDownloadRar" }      );          routes.MapRoute(          name: "ForgeHtml",          url: "china/htzd/{id}.html",          defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },              ///////////////////路由值得添加约束          constraints: new {id=@"\d+" }      );          routes.MapRoute(           name: "Default",           url: "{controller}/{action}/{id}",           defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }       );                 }    }}

D.创建HomeController.cs文件:

using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;namespace MvcRouteTest.Controllers{    public class HomeController : Controller    {        //        // GET: /Home/        public ActionResult ForbidDownloadRar()        {            return View();        }        public ActionResult Index(int? ID)        {                 if (ID.HasValue)          {               ViewBag.str ="传过来的ID为"+ ID.ToString();          }          else          {               ViewBag.str ="传过来的ID为Null";          }                       return View();        }        public ActionResult GetFile()        {            return File(Server.MapPath("~/Content/download/a/b/c/cs.rar"), "application/x-rar-compressed","cs.rar");        }    }}

E.创建相应的View:

Index.cshtml:

@{    ViewBag.Title = "Index";}<h2>Index</h2><h2>@ViewBag.str</h2><h2><a href="@Url.Content("~/Content/Download/a/b/c/cs.rar")">Rar下载测试1-使用Url帮助函数</a></h2><h2><a href="http://localhost:3310/Content/Download/a/b/c/cs.rar">Rar下载测试2-使用链接地址</a></h2><h2>@Html.ActionLink("Rar下载测试3-使用GetFile.", "GetFile", "Home")</h2><hr /><h2><a href="@Url.Content("~/Content/cs.txt")">下载cs.txt测试--使用Url帮助函数</a></h2><h2><a href="http://localhost:3310/Content/cs.txt")">下载cs.txt测试--使用链接地址</a></h2><hr /><h2><a href="@Url.Content("~/Content/cs.doc")">下载cs.doc测试--使用Url帮助函数</a></h2><h2><a href="http://localhost:3310/Content/cs.doc")">下载cs.doc测试--使用链接地址</a></h2><hr /><h2><a href="@Url.Content("~/china/htzd/8.html")">伪造静态页面--使用Url帮助函数</a></h2><h2><a href="http://localhost:3310/china/htzd/8.html">伪造静态页面--使用链接地址</a></h2>

ForbieDownloadRar.cshtml:

@{    ViewBag.Title = "ForbidDownloadRar";}<h2>禁止下载Rar文件</h2>

F.在Global.asax.cs文件中的Application_Start事件中最前面添加一行代码:

RouteTable.Routes.RouteExistingFiles =true;

(也可参阅上图)

G.通过上述代码true或false的修改,来测试Index主页的各种链接功能.
