如何将DateTime参数从View传递到ASP.net MVC5中的Controller？

Question

I am trying to pass 3 parameters, one int, and 2 datetime to a controller with no luck. I have created custom Routes, but no matter what I do it never connects. In My View I have

@Html.ActionLink("Check Availability", "Check", new { id = item.RoomID, AD = ArrivalDate.Date.ToString("dd-MM-yyyy"), DD = DepartureDate.Date.ToString("dd-MM-yyyy") }, null)

In my Controller I have

   [RoutePrefix("RoomInfoes")]
   [Route("Check/{ID},{AD},{DD}")]
    [HttpPost]
    public ActionResult Check(int? id, string AD, string DD) {

I have tried numerous arrangements of routes and views, but never can connect.

The code above returns a 404 with

Requested URL: /RoomInfoes/Check/1,06-11-2014,06-11-2014

Thanks

Answer 1

Do also have the Check Action method for serving HttpGet requests? If not, you will get 404 error.

Have you also done the routes.MapRoute in the RouteConfig.cs ? This is required to render the correct URL with @Html.ActionLink helper method.

Try adding below code in RouteConfig.cs , if not already exists.

routes.MapRoute(
            name: "RoomInfoes",
            url: "Check/{ID},{AD},{DD}",
            defaults: new
            {
                controller = "RoomInfoes",
                action = "Check",
                ID = UrlParameter.Optional,
                AD = UrlParameter.Optional,
                DD = UrlParameter.Optional
            }
            );

You don't Need Route and the RoutePrefix attribute on the Action method.

Before you use attribute routing make sure you have it enabled:

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

        routes.MapMvcAttributeRoutes(); // add this line in your route config

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

then decorate your action like this:

[Route("RoomInfoes/Check/{ID},{AD},{DD}")]
public ActionResult Test(int? id, string AD, string DD)

The RoutePrefix has been removed because it can be used only on class declaration (the code will even doesn't compile). I removed the HttpPost attribute because I assumed that you want make a GET instead of POST.

then to generate a link pointing to this action you can simply write:

@Html.ActionLink("test", "Test", "Home", new { id = 5, AD="58", DD = "58" }, null)

the result will be:

<a href="/RoomInfoes/Check/5%2c58%2c58">test</a> (the commas in your url will be url encoded)
