RestSharp: ItemChoice toujours null

Question

Je suis nouveau à RestSharp et essayant d'accéder à mon serveur subsonique par le subsonic-api. Chaque réponse est enveloppée dans une étiquette de réponse subsonique, par ex.

<subsonic-response xmlns="http://subsonic.org/restapi" 
       status="ok" version="1.10.1"> 
<artists ignoredArticles="The El La Los Las Le Les"> 
    <index name="A"> 
     <artist id="5449" name="A-Ha" coverArt="ar-5449" albumCount="4"/> 
     <artist id="5421" name="ABBA" coverArt="ar-5421" albumCount="6"/> 
     <artist id="5432" name="AC/DC" coverArt="ar-5432" albumCount="15"/> 
     <artist id="6633" name="Aaron Neville" coverArt="ar-6633" albumCount="1"/> 
    </index> 
    <index name="B"> 
     <artist id="5950" name="Bob Marley" coverArt="ar-5950" albumCount="8"/> 
     <artist id="5957" name="Bruce Dickinson" coverArt="ar-5957" albumCount="2"/> 
    </index> 
</artists> 

Xsd généré les classes suivantes pour la sérialisation:

public partial class Response 
{ 

    private object itemField; 

    private ItemChoiceType itemElementNameField; 

    private ResponseStatus statusField; 

    private string versionField; 

    [System.Xml.Serialization.XmlChoiceIdentifierAttribute("ItemElementName")] 
    public object Item 
    { 
     get 
     { 
      return this.itemField; 
     } 
     set 
     { 
      this.itemField = value; 
     } 
    } 

    [System.Xml.Serialization.XmlIgnoreAttribute()] 
    public ItemChoiceType ItemElementName 
    { 
     get 
     { 
      return this.itemElementNameField; 
     } 
     set 
     { 
      this.itemElementNameField = value; 
     } 
    } 

    public ResponseStatus status 
    { 
     get 
     { 
      return this.statusField; 
     } 
     set 
     { 
      this.statusField = value; 
     } 
    } 

    public string version 
    { 
     get 
     { 
      return this.versionField; 
     } 
     set 
     { 
      this.versionField = value; 
     } 
    } 
} 

public partial class ArtistsID3 
{ 

    private List<IndexID3> indexField; 

    public ArtistsID3() 
    { 
     this.indexField = new List<IndexID3>(); 
    } 

    public List<IndexID3> index 
    { 
     get 
     { 
      return this.indexField; 
     } 
     set 
     { 
      this.indexField = value; 
     } 
    } 
} 

public enum ItemChoiceType 
{ 

    /// <remarks/> 
    album, 

    /// <remarks/> 
    albumList, 

--- snip ---- 

Quand je suis en train de désérialiser en réponse-objet l'élément de champ est toujours nul et ItemElementName obtient la première valeur à partir de l'énumération ItemChoiceType mais la version et le statut sont correctement définis. La sortie xml-récupérée ressemble à ce qui est attendu (voir l'exemple). Ce qui fonctionne bien est la désérialisation dans ArtistsID3 mais je perds le statut.

Voici le code:

SubsonicApi api = new SubsonicApi(); 
var request = new RestRequest(); 
request.Resource = "getArtists.view"; 
request.AddParameter("v", "1.10.2"); 
request.AddParameter("c", "no name yet"); 
// Item always null! 
// var response = api.Execute<Response>(request); 
var response = api.Execute<ArtistsID3>(request); 

public T Execute<T>(RestRequest request) 
     where T : new() 
    { 
     var client = new RestClient(); 
     client.BaseUrl = new System.Uri(BaseUrl); 
     client.Authenticator = new HttpBasicAuthenticator(_accountSid, _secretKey); 
     var response = client.Execute<T>(request); 
     Console.WriteLine("RESPONSE-DATA: " + response.Content); 
     return response.Data; 
    } 

Je serais heureux si quelqu'un pouvait me diriger dans la bonne direction que je pense que la bonne façon devrait être en train d'accéder aux données via un objet de réponse. Ne sais vraiment pas comment déboguer ce comportement inattendu.
