How to implement multiple Get methods in WebApi

Question

Here I'm Trying to implement multiple Get methods but the browser througs an error Multiple actions were found that match the request. Why does this happen?

In the Api Controller I added two methods: 1. GetEmployee 2. HelloDept If I comment out one of them it's working fine.

    public class TrailController : ApiController
    {
        private IProduct Repo = new Product();

        [HttpGet]
        public IEnumerable<Employee> GetEmployee()

        {
            var x = Repo.GetEmp();
            return x;

        }
        [HttpGet]
        public IEnumerable<Department> HelloDept()

        {
            var x = Repo.GetDept();
            return x;

          }

RouteConfig.cs

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

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


            );

Change your code in RouteConfig.cs.

From:

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


        );

To:

routes.MapHttpRoute(
name: "API Default",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional });

Also, refer this- Difference between "MapHttpRoute" and "MapRoute"?

In Your WebApiConfig.cs change

`api/{controller}/{id}`

with

`api/{controller}/{action}/{id}`.

Then call the actions like -

http://localhost:port/api/controller/HelloDept
http://localhost:port/api/controller/GetEmployee


public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }
}

Multiple actions were found that match the request: GetEmployee on type Application.Api.Controllers.TrailController GetById on type Application.Api.Controllers.TrailController HelloDept on type Application.Api.Controllers.TrailController – Jan 05 '17 at 07:43
i make changes in Edit – Jan 05 '17 at 07:49
it should be `api` and not `{api}`. one more thing, you're using `ApiController`, but what you posted is a `route` for `mvc`.You sure you looking at right place? It should be an `HttpRoute` in the `WebAPiConfig.cs`. – Amit Kumar Ghosh Jan 05 '17 at 07:52
i did change also Even no Result...Wil u come on my Teamviewr – Jan 05 '17 at 07:54
I don't have teamviewer, dude sorrry. But as you can see both the actions are being called, I believe that you are putting your code in a wrong place. – Amit Kumar Ghosh Jan 05 '17 at 08:12
