Comment créer un Swiss QR Code V2.3 ?

L'exemple de code suivant en C# .NET montre comment créer le format de données pour le Swiss QR Code selon les directives de mise en œuvre du Swiss QR-bill version 2.3.

La version 2.3 exige des adresses structurées. La rue, le numéro de bâtiment, le code postal et la ville doivent donc être fournis dans des champs séparés. Le type d'adresse doit être réglé sur S.
