I have no idea what you mean about your reference file but if you need to output as an array you might want to look a little deeper are the generics in dotnet. Any object which implements the IList interface has the ToArray method. This means you can convert a collection to an array with a single method call and you will be returned an array of objects with the type of your generic collection. So if the type was a Person you would get an array of Person objects.

To be honest, arrays are rather archaic in their behavior. Once the generic collection came into existence the classic array has been a dying breed.
