Je récupère le XML de Twitter via OAuth.
Je fais une demande à http://twitter.com/account/verify_credentials.xml , qui retourne le XML suivant:
<?xml version="1.0" encoding="UTF-8"?>

J'utilise le code suivant pour désérialiser:
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);
}
Et j'ai les éléments suivants pour ma 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; }
}
Mais quand il désérialise le XML ci-dessus, l'application lance ce qui suit:
$ exception {"Il y a une erreur dans le document XML (2, 2)."} System.Exception {System.InvalidOperationException}
InnerException {"<user xmlns = ''> n'était pas attendue."} System.Exception {System.InvalidOperationException}
Maintenant, j'ai cherché et la meilleure solution que je peux trouver est d'ajouter des espaces de noms vides au sérialiseur lorsque vous sérialisez le contenu, mais je ne le sérialise pas, donc je ne peux pas.
J'ai également un code pour recevoir des statuts, ce qui fonctionne bien.
Alors, quelqu'un peut-il m'expliquer pourquoi l'erreur se produit? Ainsi qu'une solution possible?
Merci d'avance.
XmlSerializer
. Alors vérifiez cela aussi.
