Web APi Routing Understanding - asp.net-mvc

Question

I have created a new controller called WebPortalController but when I call it or try to call it via the browser I couldnt access the below method just said resource is not found. Do I need to add a new routing to the RoutesConfig.cs code if so how.?
namespace WebApi.Controllers
{
public class WebPortalController : ApiController
{
// GET api/webportal
private WebPortEnterpriseManagementDa _da = new WebPortEnterpriseManagementDa();
public ManagedType Get(string name)
{
ManagedType items = _da.GetManagedType(name);
return items;
}
// POST api/webportal
public void Post([FromBody]string value)
{
}
// PUT api/webportal/5
public void Put(int id, [FromBody]string value)
{
}
// DELETE api/webportal/5
public void Delete(int id)
{
}
}
}
Routes file
namespace WebApi
{
public class RouteConfig
{
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
}
}

The route config you have shown is for MVC routes and is located in the App_Start/RouteConfig file. Check that you have a default API route set in your App_Start/WebApiConfig:
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
Then you will need to change the parameter name in your Get method to match the routing parameter:
public ManagedType Get(string id)
{
ManagedType items = _da.GetManagedType(name);
return items;
}
This should allow you to call your Get method through a browser using:
localhost:55304/api/WebPortal/Test
In order to test out your Post/Put/Delete methods you will need to use Fiddler or a browser addin such as Postman
