Exemples
L’exemple de code suivant crée un module dynamique, un type abstrait nommé Sampleet une méthode abstraite nommée TestMethod.
TestMethod prend un paramètre ref (ByRef dans Visual Basic) de type Sample, un pointeur vers le type Sample et un tableau de type Sample. Elle retourne un tableau à deux dimensions de type Sample. L’exemple de code enregistre le module dynamique sur le disque, afin de pouvoir l’examiner avec le Ildasm.exe (désassembleur IL).
