I have a program written in C# that handles communication between two
pieces of software.  My problem only deals with getting a text array
from one program to this C#  "Bridge".  I can get the text array to the
bridge, where it is received as a system.object.  My problem is casting
this system.object to a string array.  The code I'm using is below.

System.Array advArgs = args as System.Array;  //creates array for
parameters being received

object advCommands = advArgs.GetValue(2);    //gets the 3rd parameter
which is the array from the external software, stores it in
advCommands.

GCListOrArray GCarray = new GCListOrArray();  //GCarray is new
GCListOrArray interface, this interface was written by the external
software develpoer for applications like this.

GCarray = (GCListOrArray)advCommands;     //Convert advCommands to
GCListOrArray interface type

Basically, when I try to WriteLine, the compiler says that it cannot
cast System.__ComObject.  I have tried everyway I know of casting it,
but had no luck. Any suggestions?

Thanks in advance.
