ASP.NET MVC对URL匹配操作

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

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

            // 1、使用parameter做模糊匹配
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

// 2、使用字面量做精确匹配
routes.MapRoute(
       name: "Default2",
       url: "admin/{controller}/{action}/{id}",
       defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

// 3、不允许连续的URL参数
routes.MapRoute(
       name: "Default3",
       url: "{language}-{country}/{controller}/{action}/{id}",
       defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

routes.MapRoute(
       name: "Default4",
       url: "{controller}/{action}/{id}/{*plus}",
       defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

public ActionResult Index(string plus)
{
       string value = string.Format("plus={0}", plus);
       ViewData["msg"] = value;
       return View();
}

routes.MapRoute(
        name: "Default5",
        url: "{controller}/{action}/{id}/{filename}.{ext}",
        defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
