passing variants from C# client to MFC Automation enabled app

Hello

When try to send a ref of array string to the variant pointer we get DISP_E_TYPEMISMATCH exception.
Eg:
MFC App is OLE Automation enabled.

Code:

---

void Funct1(VARIANT *pVar) //is the MFC app function

---

from C# side we invoke this as follows

Code:

---

string [] str = new string[100];
Object obj = (Object) str;
mfcAutoApp.Funct1(ref obj); // this would throw the DISP_E_TYPEMISMATCH exception.

---

Any suggestions on this...

-thanks
