Estoy sacando el XML de Twitter a través de OAuth.
Estoy haciendo una solicitud a http://twitter.com/account/verify_credentials.xml , que devuelve el siguiente XML:

Estoy usando el siguiente código para deserializar:
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);
}
Y tengo lo siguiente para mi User
clase:
[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; }
}
Pero cuando se deserializa el XML anterior, la aplicación arroja lo siguiente:
$ excepcion {"Hay un error en el documento XML (2, 2)."} System.Exception {System.InvalidOperationException}
InnerException {"<user xmlns = ''> no se esperaba."} System.Exception {System.InvalidOperationException}
Ahora he buscado y la mejor solución que puedo encontrar es agregar espacios de nombres en blanco al serializador cuando serializas el contenido, pero no lo estoy serializando, así que no puedo.
También tengo un código para recibir estados, que funciona bien.
Entonces, ¿alguien puede explicarme por qué está ocurriendo el error? ¿Y una posible solución?
Gracias por adelantado.
XmlSerializer
. Así que revisa eso también.
