Exemples

L’exemple de code ci-dessous illustre l’utilisation d’informations GetParameters sur les paramètres passés à une méthode générée dynamiquement.


TypeBuilder myType1 = myModBuilder.DefineType("MyMathFunctions",
                TypeAttributes.Public);

MethodBuilder myMthdBuilder = myType1.DefineMethod("AddToRefValue",

                typeof(void),
                new Type[] { Type.GetType("System.Int32&"),
                         typeof(int) });
ParameterBuilder myParam1 = myMthdBuilder.DefineParameter(1,
                ParameterAttributes.Out,
