PowerDesigner - Access BusinessRules of Model

Question

How I can iterate in C# over the BusinessRules of a powerdesigner model? This does not work:

private static void importModelPackages(PdCDM.Model pdModel){
        foreach (PdCDM.ObjectCol curPDBusinessRule in pdModel.BusinessRules){ /*...*/ }
}

Answer 1

foreach (PdCommon.BusinessRule curPDBusinessRule in pdModel.BusinessRules) {
   /*...*/ 
}

Another possibility:

PdPDM.ObjectCol col = pdModel.BusinessRules;
foreach (PdCommon.BusinessRule rul in col) {
   /*...*/ 
}
