ASP.NET MVC自訂路由 - 實現IRouteConstraint限制控制器名（轉載）

標籤：

自訂約束前

namespace MvcApplication2{    public class RouteConfig    {        public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");             //預設            routes.MapRoute(                name: "Default",                url: "{controller}/{action}/{id}",                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }            );        }    }}

實現IRouteConstraint介面

using System;using System.Web.Routing; namespace MvcApplication2.Extension{    public class ExcludeController : IRouteConstraint    {        private readonly string _controller;         public ExcludeController(string controller)        {            _controller = controller;        }        public bool Match(System.Web.HttpContextBase httpContext, Route route, string parameterName, RouteValueDictionary values,
 RouteDirection routeDirection)        {            //如果路由中拿到的controller值與約束設定的值相等，就返回false            return !string.Equals(values["controller"].ToString(), _controller, StringComparison.OrdinalIgnoreCase);        }    }}

 

路由添加約束

using System.Web.Mvc;using System.Web.Routing;using MvcApplication2.Extension; namespace MvcApplication2{    public class RouteConfig    {        public static void RegisterRoutes(RouteCollection routes)        {            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");             //預設            routes.MapRoute(                name: "Default",                url: "{controller}/{action}/{id}",                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },                constraints: new { controller = new ExcludeController("RentalProperties") }            );        }    }} 

 

效果

可見，加上自訂約束後，帶RentalProperties名稱的控制器將被限制。
