By default ArrayList ToArray copies the list to object[]. There is an
override that allows the specification of a type:
ArrayList.ToArray(System.Type)... however, I have been unable to correctly
specify the system type or to figure out how to easily convert the object[]
to an int[].
Any ideas??

Thanks in advance.
Chuck

If the ArrayList contains all boxed ints you can do

int[] arr = (int[])yourArrayList.ToArray(typeof(int));
