JSON ne peut pas désérialiser le tableau JSON dans le type

Question

Je continue d'avoir des problèmes pour tenter de désérialiser ce fichier JSON, même après avoir essayé plusieurs approches.

Voici le JSON qui est retourné par le service Web:

[

     {

Je sais très laid. Malheureusement, c'est le service web de quelqu'un d'autre, donc je ne peux pas faire grand-chose. J'ai été déconner avec la classe modèle C# et n'arrive pas vraiment à le faire fonctionner.

Appel de la méthode:

Classe Modèle:

[JsonObject(MemberSerialization.OptIn)] 
public class BibleGatewayVerse 
{ 
    [JsonProperty("osis")] 
    public string Reference { get; set; } 
    [JsonProperty("content")] 
    public string Content { get; set; } 
    [JsonProperty("footnotes")] 
    public List<string> Footnotes { get; set; } 
    [JsonProperty("crossrefs")] 
    public List<string> CrossReferences { get; set; } 
} 

[JsonObject(MemberSerialization.OptIn)] 
public class BibleGatewayVerses 
{ 
    [JsonProperty("data")] 
    public List<BibleGatewayVerse> Verses; 
} 

Je l'ai utilisé des outils tels que json2csharp.com et ils génèrent la même chose. J'ai aussi joué avec l'utilisation de tableaux au lieu de List, mais en vain. En outre, j'ai également essayé de remplacer la liste de notes par l'objet type (comme recommandé par json2sharp).

Toute aide serait grandement appréciée.

Answer 1

Vos données JSON est enveloppé dans un tableau, vous devez désérialiser à un tableau de votre type

JsonConvert.DeserializeObject<BibleGatewayVerses[]>(jsonData); 

Hope this helps

Answer 2

Je pense que vous devriez suivre comme ça

public class BibleGatewayVerse 
{ 

    [JsonProperty("data")] 
    public Datum[] Data { get; set; } 
} 


public class Datum 
{ 

    [JsonProperty("osis")] 
    public string Osis { get; set; } 

    [JsonProperty("content")] 
    public string Content { get; set; } 

    [JsonProperty("footnotes")] 
    public object[] Footnotes { get; set; } 

    [JsonProperty("crossrefs")] 
    public string[] Crossrefs { get; set; } 
}
