Bonjour,
Je cherche à sérialiser en XML un objet qui est crée par des classes qui dépendent les unes des autres, mais j’obtiens l'erreur :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

InvalidCastException*: Impossible d'effectuer un cast d'un objet de type 'Asc_to_GMA3.GMA3' en type 'System.Collections.Generic.List`1[Asc_to_GMA3.GMA3]'.

voici les classes:

 Dim gma3bis As New GMA3
 
 Dim serializer As New XmlSerializer(GetType(List(Of GMA3)))
 ' Dim writer As New XmlTextWriter("C:\Users\hp-bureau\Desktop\test-premier-export.xml", Encoding.UTF8)
 
 Using writer As New StreamWriter("C:\Users\hp-bureau\Desktop\test-premier-export.xml")
     serializer.Serialize(writer, gma3bis)
 End Using

pouvez-vous m'aider je ne sais pas ce qui ce passe.
Merci d'avance.

Pour résumer, l'erreur dit qu'il ne peut pas convertir un GMA3 en liste de GMA3
gma3bis est de type de GMA3
Tu créés un xmlserializer en lui indiquant de gérer une liste de GMA3
et tu sérialises gma3bis, qui n'est pas une liste, donc expliqué ainsi, je crois que tu peux deviner où se situe le problème, non?

Merci de m'avoir répondu.
Effectivement c'était tout simple.
