Late Binding in C#

[Frank Oquendo]

I have an object that can only be communicated with via late binding (I'm
assuming it's all about the IDispatch interface). It's type library is of no
use as this object cannot be cast to any of the types listed in the TLB
file.

I already know how to operate this object in VB6 but I can't figure out how
to work with it in C#. For example this object has an Items collection. In
VB6 it was simple as obj.Items("nth"). How can I do the same in C#?

Okay, I've come across <object>.GetType().InvokeMethod and it looks rather
promising. But there's a problem: some of the methods I need to invoke
require an out parameter. InvokeMethod accepts an arry of objects as
arguments to the method you're invoking.

Any idea how I can pass an out parameter via an array?

I *think* that the out parameter will be in the array you passed when the
call returns.

Found it: pass null for the args parameter.
