MVC5路由改为小写、Route特性自定义Action路由

1.要想使用Route特性自定义Action名称，需要注册Mvc路由特性。

在RouteConfig的RegisterRoutes方法里，调用：routes.MapMvcAttributeRoutes();

这里需要注意的是，如果Controller继承了一个父Controller,且父类Controller中，有泛型方法，就会报错：“您不能调用控制器xxx上的xx方法，因为该方法是一种泛型方法。”

如在父类Controller中定义了：pulbic JsonResult Success(string msg)。

这里需要吧pulbic访问修饰符改成protected就好，

2.路由全改为小写，需要重写路由匹配规则，代码如下：

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

            routes.MapMvcAttributeRoutes();

            routes.MapLowerCaseUrlRoute("Default",
                    "{controller}/{action}/{id}",
                     new { controller = "Home", action = "Index", id = UrlParameter.Optional });

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

    public class LowerCaseUrlRoute : Route
    {
        private static readonly string[] requiredKeys = new[] { "area", "controller", "action" };

        public LowerCaseUrlRoute(string url, IRouteHandler routeHandler)
            : base(url, routeHandler) { }

        public LowerCaseUrlRoute(string url, RouteValueDictionary defaults, IRouteHandler routeHandler)
            : base(url, defaults, routeHandler) { }

        public LowerCaseUrlRoute(string url, RouteValueDictionary defaults, RouteValueDictionary constraints, IRouteHandler routeHandler)
            : base(url, defaults, constraints, routeHandler) { }
        public LowerCaseUrlRoute(string url, RouteValueDictionary defaults, RouteValueDictionary constraints, RouteValueDictionary dataTokens, IRouteHandler routeHandler)
            : base(url, defaults, constraints, dataTokens, routeHandler) { }

        public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
        {
            LowerRouteValues(requestContext.RouteData.Values);
            LowerRouteValues(values);
            LowerRouteValues(Defaults);
            return base.GetVirtualPath(requestContext, values);
        }

        private void LowerRouteValues(RouteValueDictionary values)

            foreach (var key in requiredKeys)

                var value = values[key];
                if (value == null) continue;

                var valueString = Convert.ToString(value, CultureInfo.InvariantCulture);
                if (valueString == null) continue;

                values[key] = valueString.ToLower();
            }
