ASP.NET WebAPI路由参数

Question

I'm trying to make an action with 2 parameters, 1 is optional I'm trying with

 [HttpGet, Route("movies/date/{dateMin}&{dateMax}")]

But it's not working. 'dateMax' is optional parameter, and when it's not given it should be the same value as dateMin Already tried with

 [HttpGet, Route("movies/date/{dateMin}&{dateMax?}")]

But it's not working either. I dont want to have something like

{dateMin}/{dateMax}

Is there other possibility to do that?

Answer 1

You should be doing that in your RouteConfig.cs

 routes.MapRoute(
        name: "Movies",
        url: "{controller}/{action}/{dateMin}/{dateMax}",
        defaults: new { controller = "movies", action = "date", dateMax= UrlParameter.Optional }
        );

Your Route should be like this

"{controller}/{action}/{dateMin}/{dateMax}"

Answer 2

You need to segregate the route parameters in your route using a slash and not using the query string notation ( & ).

[HttpGet, Route("movies/date/{dateMin}/{dateMax?}")]
public IHttpActionResult MoviesDate(DateTime dateMin, DateTime? dateMax){
}

There is no need to change the route config if you use RoutAttribute
