can you index a property and then assigned those indexes a sub-property

[msnews.microsoft.com]

Okay so let me see if i understand you correctly. I have two classes. Class
A and Class B. I give class A 5 properties
int prop1(){}
int prop2(){}
int prop3(){}
int prop4(){}
classB prop5(){}

what i would like to do is to create a 5th property and make its type equal
to ClassB. but i would also like to index this property too. BTW Class B
also has some properties to it. So in the end i would be able to access my
items like this:

classA xyz = new classA();
xyz.prop1=1;
xyz.prop2=2;
xyz.prop3=3;
xyz.prop4=4;

xyz.prop5[0].prop1=1;
xyz.prop5[0].prop2=2;

xyz.prop5[1].prop1=1;
xyz.prop5[1].prop2=2;

I remember doing stuff like this a while ago in VB6 but i'm pretty new to C#
and i'm just learning out to do this sort of stuff. I hope that explain
helps a little bit more. I think i understand what your saying though.
