通过实现IRouteConstraint接口，实现对某个控制名进行限制。本篇把重点放在自定义约束，其余部分参考：
自定义约束前
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}"); //默认routes.MapRoute(
name: "Default", url: "{controller}/{action}/{id}",defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}
}
效果
自定义约束后
□ 实现IRouteConstraint接口
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值与约束设定的值相等，就返回falsereturn !string.Equals(values["controller"].ToString(), _controller, StringComparison.OrdinalIgnoreCase);
}
}
}
□ 路由添加约束
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}"); //默认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
可见，加上自定义约束后，带RentalProperties名称的控制器将被限制。
