Xml Serialization ne cr�e pas les objets que je veux

Bonjour � tous,

J'essaie de r�cup�rer des donn�es � partir d'un fichier xml.

Selon le code plus bas, il semble que �a ne r�ussissent pas � cr�er des objets...

J'ai selon les tests que je fais quelques erreurs diff�rentes.

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

Sinon, si j'utilise par exemple un fichier que j'ai cr�er moi m�me � partir d'un xsd, �a me renvoie une erreur de node....


J'ai joint mes fichiers Xml, xsd et cpp. Le fichier CdbMapping.xml � �t� cr��r � la main et cr�er 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 d�finit un peu plus bas??? c'est peut etre pour �a que je ne peux affecter de CdbItem dans mon CdbGroup.

Il faut aussi dire que la classe a �t� g�n�r� par l'outil xsd.exe (pour moi tout dans un .h, c'est assez �trange)

Code:

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 �a sert de pointeur --> j'avais jamais vu �a avant. J'ai lu un peu, mais je suis pas certain de comprendre le principe d'emboitage.. (peut-etre un lien pourrait m'�clairer, parce que ce que j'ai trouv� est tr�s mince)
