How to call the API controller through the client?

Question

API

There is a project with regular controllers, there is a project with api controllers. How to call from a regular api controller through an http client (a class library that is responsible for generating requests to the ip controller), there are links to the project, but the api controller method does not work

Answer 1

Class library, client for making queries

public CountryDTO find(int id)
        {
            try
            {
                HttpClient client = new HttpClient();
                client.BaseAddress = new Uri(Base_URL);
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                HttpResponseMessage response =  client.GetAsync("country/" + id.ToString()).Result;

                if (response.IsSuccessStatusCode)
                    return response.Content.ReadAsAsync<CountryDTO>().Result;
                return null;
            }
            catch
            {
                return null;
            }
        }

The usual controller from which we call the client

CountryClient CC = new CountryClient();
 public ActionResult Details(int id)
        {
            
            CountryDTO a = CC.find(id);
            
            return View(a);

        }

and API controller where the request should go after the client, but for some reason it doesn’t go

[ResponseType(typeof(CountryDTO))]
        public IHttpActionResult GetCountry(int id)
        {
            countryRepository.GetCoById(id);
            return Ok(countryRepository.GetCoById(id));
        }
