Sto inserendo l'XML da Twitter tramite OAuth.
Sto facendo una richiesta a http://twitter.com/account/verify_credentials.xml , che restituisce il seguente XML:

Sto usando il seguente codice per deserializzare:
public User VerifyCredentials()
{
string url = "http://twitter.com/account/verify_credentials.xml";
string xml = _oauth.oAuthWebRequestAsString(oAuthTwitter.Method.GET, url, null);
XmlSerializer xs = new XmlSerializer(typeof(User),"");
MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(xml));
return (User)xs.Deserialize(ms);
}
E ho il seguente per la mia User
classe:
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
public partial class User
{
[XmlElement(ElementName = "id")]
public long Id { get; set; }
[XmlElement(ElementName = "name")]
public string Name { get; set; }
[XmlElement(ElementName = "screen_name")]
public string ScreenName { get; set; }
[XmlElement(ElementName = "location")]
public string Location { get; set; }
[XmlElement(ElementName = "description")]
public string Description { get; set; }
[XmlElement(ElementName = "profile_image_url")]
public string ProfileImageUrl { get; set; }
[XmlElement(ElementName = "url")]
public string Url { get; set; }
[XmlElement(ElementName = "protected")]
public bool Protected { get; set; }
[XmlElement(ElementName = "followers_count")]
public int FollowerCount { get; set; }
[XmlElement(ElementName = "profile_background_color")]
public string ProfileBackgroundColor { get; set; }
[XmlElement(ElementName = "profile_text_color")]
public string ProfileTextColor { get; set; }
[XmlElement(ElementName = "profile_link_color")]
public string ProfileLinkColor { get; set; }
[XmlElement(ElementName = "profile_sidebar_fill_color")]
public string ProfileSidebarFillColor { get; set; }
[XmlElement(ElementName = "profile_sidebar_border_color")]
public string ProfileSidebarBorderColor { get; set; }
[XmlElement(ElementName = "friends_count")]
public int FriendsCount { get; set; }
[XmlElement(ElementName = "created_at")]
public string CreatedAt { get; set; }
[XmlElement(ElementName = "favourties_count")]
public int FavouritesCount { get; set; }
[XmlElement(ElementName = "utc_offset")]
public int UtcOffset { get; set; }
[XmlElement(ElementName = "time_zone")]
public string Timezone { get; set; }
[XmlElement(ElementName = "profile_background_image_url")]
public string ProfileBackgroundImageUrl { get; set; }
[XmlElement(ElementName = "profile_background_tile")]
public bool ProfileBackgroundTile { get; set; }
[XmlElement(ElementName = "statuese_count")]
public int StatusesCount { get; set; }
[XmlElement(ElementName = "notifications")]
public string Notifications { get; set; }
[XmlElement(ElementName = "geo_enabled")]
public bool GeoEnabled { get; set; }
[XmlElement(ElementName = "Verified")]
public bool Verified { get; set; }
[XmlElement(ElementName = "following")]
public string Following { get; set; }
[XmlElement(ElementName = "status", IsNullable=true)]
public Status CurrentStatus { get; set; }
}
Ma quando sta deserializzando l'XML sopra, l'applicazione genera quanto segue:
$ exception {"Errore nel documento XML (2, 2)."} System.Exception {System.InvalidOperationException}
InnerException {"<user xmlns = ''> non previsto."} System.Exception {System.InvalidOperationException}
Ora ho cercato e la soluzione migliore che posso trovare è quella di aggiungere spazi vuoti al serializzatore quando si serializza il contenuto, ma non lo sto serializzando, quindi non posso.
Ho anche del codice per ricevere gli stati, che funziona bene.
Qualcuno può spiegarmi perché si sta verificando l'errore? Oltre a una possibile soluzione?
Grazie in anticipo.
XmlSerializer
. Quindi controlla anche quello.
