We are developing an iOS shopping cart application in c# and Visual Studio 2017 for Xamarin. We are using rest web services, Here I could not call web services. when I call web service I am getting null response with an error[ConnectFailure (Connection refused)]. My question is How to get a value from localhost URL like [http://localhost:56207/api/Users/Raju/Password@123]. When I enter this URL in the browser I am getting true or false depending upon user and password validation.I request you to help me to resolve this issue.I paste the code in below:
 public class RestInterfaceImp : IRestLogin
    {
    HttpClient client;
    private const string WebServiceUrl = "http://localhost:56207/api/Users/Raju/Password@123";
    public async Task<List<User>> RefreshDataAsync()
    {
        try
        {
            var httpClient = new HttpClient();
            var resp = await httpClient.GetAsync(WebServiceUrl);
            if (resp.IsSuccessStatusCode)
            {
                var respStr = await resp.Content.ReadAsStringAsync();
               var listaAtletas = JsonConvert.DeserializeObject<List<User>>(respStr);
            }
        }
        catch (HttpRequestException e)
        {
            Debug.WriteLine(e.InnerException.Message);
        }
        return null;
    }
}
