[ASP.NET C# - XML] - Ajout
Bonsoir tout le monde,
J'ai suit un tutorial pour créer une page ASP .NET qui sert à écrire dans un fichier XML,
Je n'ai aucune erreur lors de l'éxécution mais rien n'est écrit sur ma page XML!!!
En tout cas il me semble que le problème est au niveau de l'entete de la page .aspx
Merci pour l'aide,
