Answers

Question

J'ai l'application xamarin.forms pour laquelle j'essaye de relier localhost du PC au simulateur d'Iphone dans mac, IAM utilisant l'adresse d'Ip pour la connexion,

private string Uri = "http://192.168.0.16:62271/";//Windows Ip address:localhost port number    
private string GetDishesUrl = "api/DishDetails/GetDishDetails?id=5"; 

try{ 
    var httpClient = new HttpClient();
    httpClient.BaseAddress = new Uri(Uri);

    var response = await httpClient.GetAsync(new Uri(Uri + GetDishesUrl));
    var stringAsync = await response.Content.ReadAsStringAsync();

    if (response.IsSuccessStatusCode)
    {
        var responseJson = stringAsync;
        return JsonConvert.DeserializeObject<List<DishDetails>>(responseJson);
    }
}
catch(Exception ex)
{
}

Voici iam obtenir l'exception suivante:

en cours d'exécution web dans Windows il fonctionne comme prévu. Lorsque vous essayez de vous connecter à mac donnant une erreur.J'ai suivi différentes approches de l'Internet, mais pas d'entre eux ont travaillé.

EDIT: J'ai désactivé le pare-feu et connecté mac et pc sous le même Wifi alors la réponse est nulle et l'exception est également nulle.
