Com Variant Marshalling Question

[Bob]

I have been trying to us an unmanaged dll for a while now with no good
results. Most of the dll methods i can use and have been. I however
have a problem with this one. I am supposed to ref 15 objects as the
following type.

This is one of the 15 variables i am using.

[MarshalAs(Unman agedType.SafeAr ray | UnmanagedType.I 4)]
object secondaryFieldS coreDataSA = new int [8];

private myMethod()
{
int i = failedMethod(re f secondaryFieldS coreDataSA,ref ...);
...............
}

I keep getting an invalid param used. I have contacted the company
that created the dll and they had me try using the .SafeArray | I4 and
it still doesn't work. I have tried almost everything. I am missing
something. I visual studio it is asking for 15 ref objects and in the
documentation from the vendor it should be returned as an array of
type long items. Any help is greatly appreciated.
Need Help,
Bob;
