Accessing members of an Array of Objects using GetValue

[MXL]

Hello,

I have 2 classes: MyClass1 and MyClass2.
MyClass1 contains an Array(3 elements) of MyClass2, which contains an array
of bytes(3 elements).

__gc public class MyClass2
{
public:
Array* arry2;
MyClass2()
{
arry2 = Array::CreateInstance( __typeof(unsigned char), 3);
}
}

__gc public class MyClass1
{
public:
Array* arry1;
MyClass1()
{
arry1 = Array::CreateInstance( __typeof(MyClass2), 3);
}
}
I would like to access the array of byes:

MyClass1* mC = new MyClass1;
mC->arry1->GetValue(0)->arry2->GetValue(0) //Results in build error
The compiler does not allow me to do this:
error C2039: 'arry2' : is not a member of 'System::Object'

I recognize that GetValue(int index) returns Object* and does not have an
'arry2' member at compile-time,
but what can I do to access arry2?
Thank you.
