[C#]Parseur de fichier .reg

:salut:

Vu qu'une fois de plus j'ai du le faire moi même ... (:aie:)
Voici donc un parseur de fichier .reg. Il prend en entrée un StreamReader (tout en sachant que normalement un fichier reg c'est de l'unicode pas de l'ascii, du moins de puis Windows 2000/XP) et en sortit donne une arborescence de clefs/valeurs sous formes de classes. Normalement ça gère bien toutes les valeurs hexa en les convertissant en string pour les MULTI_SZ entre autre et il reconnais certains caractères d'échappements.

Normalement c'est du C# 3.0, mais c'est juste la manière d'écrire les propriétés qui poserai problème à une utilisation à partir de VS 2005 (vu que ça marche en C# 2.0 avec VS 2008). Donc si ça pose problème, il suffit de compléter les propriétés avec les champs correspondants.

Le code donc :

Bien, ça a le mérite d'exister maintenant. Un code à garder sous la main.

J'ai fait un petit test rapide, premier essai, premier plantage. Une valeur de type DWORD codé ainsi ne passe pas :

Code:

---

"ProcessImageColumnWidth"=dword:000000c8

---

C'est pas bien méchant, je pense, une histoire d'hexa à gérer. En VB je saurais faire, mais en C# je suis pas encore assez à l'aise.

Alala ... il était tard j'ai pas fait suffisamment de tests. Je corrige et je reviens.

Voilà, j'ai modifié le premier message avec le nouveau code, et je l'ai testé sur

Code:

Et ça a marché nikel, donc ça devrais aller.

Sinon pour la conversion en VB ça donne ça (pas testé):

Excellent !
Peut être faudrait il préparer un bibliothèque C# made in developpez.com ?

Il n'y a pas de tel projet actuellement dans la section.
Mais on peut s'en sortir avec ça : http://dotnet.developpez.com/sources/ :roll:

Oui mais ça pourrait être un bon projet !

ça veux dire que tu te proposes pour la créer ? :mrgreen::aie:

Y participer dans tous les cas je pense.
La créer, je ne sais pas si j'aurais assez de temps mais ça pourrait être intéressant non ?
