Deserialization Json apres requete API Rest
Bonjour
J'essaye sans success de deserializer le résultat d'une requête sur une API rest
Ma compréhension a certainement dérapé qq part et je n'ai pas encore trouvé la bonne explication
Voici ma requête
Code:

| client.BaseAddress = new Uri(UR);
// Add an Accept header for JSON format.
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// List data response.
HttpResponseMessage response = client.GetAsync(urlParameters).Result;
if (response.IsSuccessStatusCode)
{
var json = response.Content.ReadAsStringAsync().Result;
JsonConvert.DeserializeObject<C_Record16>(json); // Ne fonctionne pas ???
} |
La desérialisation me donne l'erreur suivante :
Citation:
Envoyé par JsonConvert.DeserializeObject<C_Record16>(json)
An unhandled exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll
Additional information: Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'TestGPS4NetRest.C_Record16' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.
To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.
Path '', line 1, position 1.
Pourtant ma chaine Json resultat me semble correcte
Code:
[{\"ALT\":\"17.70\",\"COG\":\"320.90\",\"DLOG\":\"1.00\",\"ENGINESTAT\":\"0\",\"ERROR\":0,\"FAVNETSTAT\":\"0\",\"GPRSSTAT\":\"1\",\"GSMLVL\":\"73.33\",\"GSMREGSTAT\":\"1\",\"GUS\":\"9\",\"IBAUTHSTAT\":\"0\",\"LAT\":\"50.901020\",\"LON\":\"3.407278\",\"NAVST\":\"1\",\"NST\":1,\"PANICBUTTONSTAT\":\"0\",\"PDOP\":\"2.4\",\"PRIVATESTAT\":\"0\",\"RELAYSTAT\":\"0\",\"ROAMINGSTAT\":\"1\",\"SBN\":\"08\",\"SEQ\":null,\"SOG\":\"0.00\",\"SWV\":\"22\",\"TIMESTAMP\":\"2016-11-13 07:00:09\",\"TRIGGER_SOURCE\":null,\"WARN\":0,\"gps_id\":\"2270\",\"id\":\"485\",\"msg_source\":\"2\"}]
Et j'ai aussi très patiemment construit ma classe destination en vérifiant plusieurs fois (ci dessous)
Quelle est mon erreur ?
Merci de votre aide
