Xml Serialization ne crée pas les objets que je veux

Bonjour à tous,

J'essaie de récupérer des données à partir d'un fichier xml.

Selon le code plus bas, il semble que ça ne réussissent pas à créer des objets...

J'ai selon les tests que je fais quelques erreurs différentes.

Dans le code actuel suivant, les objets à l'intérieur de TEST2 reste à undefined value... ce qui est embetant.

Sinon, si j'utilise par exemple un fichier que j'ai créer moi même à partir d'un xsd, ça me renvoie une erreur de node....


J'ai joint mes fichiers Xml, xsd et cpp. Le fichier CdbMapping.xml à été créér à la main et créer les erreurs de nodes...

Application de TEST

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

CdbMappingList^ test = gcnew CdbMappingList; CdbMappingList^ test2 = gcnew CdbMappingList; test->CdbGroup = gcnew CdbGroup; test->CdbGroup->name = "ADO"; test->CdbGroup->CdbItem = gcnew CdbItem; test->CdbGroup->CdbItem->AccessRight = AccessType::Read; test->CdbGroup->CdbItem->AccessRightSpecified = true; test->CdbGroup->CdbItem->CdbLabelName = "LABEL 1"; test->CdbGroup->CdbItem->DefaultValue = "4"; test->CdbGroup->CdbItem->Type = LabelType::INT4; test->CdbGroup->CdbItem->Index = 0; test->CdbGroup->CdbItem->IndexSpecified = true; Serializer<CdbMappingList>::create(".\\Xml\\cdbMapping2.xml", test); Serializer<CdbMappingList>::start(".\\Xml\\cdbMapping2.xml", test2);

Je suis un peu nouveau avec la CLI et je me demandais, est-ce normal qu'il n'y ait pas de constructeur pour la classe définit un peu plus bas??? c'est peut etre pour ça que je ne peux affecter de CdbItem dans mon CdbGroup.

Il faut aussi dire que la classe a été généré par l'outil xsd.exe (pour moi tout dans un .h, c'est assez étrange)

Code:

1 2 3 4 5 6 7 8 9 10 11

public ref class CdbGroup { private: cdbTest::CdbItem^ cdbItemField; private: System::String^ nameField; /// <remarks/> public: property cdbTest::CdbItem^ CdbItem { cdbTest::CdbItem^ get(); System::Void set(cdbTest::CdbItem^ value); }

et aussi, le Caret ( ^ ) est-ce que ça sert de pointeur --> j'avais jamais vu ça avant. J'ai lu un peu, mais je suis pas certain de comprendre le principe d'emboitage.. (peut-etre un lien pourrait m'éclairer, parce que ce que j'ai trouvé est très mince)
