具有任意数量的键值对的ASP.NET路由 – 是否可能？

public class MyRoute : Route
{
    public MyRoute()
        : base(
            "{controller}/{action}/id/{*parameters}",new MvcRouteHandler()
        )
    {
    }

    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        var rd = base.GetRouteData(httpContext);
        if (rd == null)
        {
            return null;
        }

        string parameters = rd.GetRequiredString("parameters");
        IDictionary<string,string> parsedParameters = YourExtensionMethodThatYouAlreadyWrote(parameters);
        rd.Values["parameters"] = parsedParameters;
        return rd;
    }

    public override VirtualPathData GetVirtualPath(RequestContext requestContext,RouteValueDictionary values)
    {
        object parameters;
        if (values.TryGetValue("parameters",out parameters))
        {
            var routeParameters = parameters as IDictionary<string,object>;
            if (routeParameters != null)
            {
                string result = string.Join(
                    "/",routeParameters.Select(x => string.Concat(x.Key,"/",x.Value))
                );
                values["parameters"] = result;
            }
        }
        return base.GetVirtualPath(requestContext,values);
    }
}

可以这样注册：

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

    routes.Add("my-route",new MyRoute());

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

现在您的控制器操作可以采用以下参数：

public ActionResult SomeAction(IDictionary<string,string> parameters)
{
    ...
}

就产生这种模式的链接而言,它很简单：

@Html.RouteLink(
    "Go","my-route",new {
        controller = "Foo",action = "Bar",parameters = new RouteValueDictionary(new { 
            key1 = "value1",key2 = "value2",}) 
    }
)

或者如果你想要< form>：

@using (Html.BeginRouteForm("my-route",new { controller = "Foo",parameters = new RouteValueDictionary(new { key1 = "value1",key2 = "value2" }) }))
{
    ...    
}
