如何使用列表制作二维数组 <T> ？

Question

I am using
System::Collection::Generics::List

Say I have a List<String^> example;
I am able to get the 0th element using example[0].

Currently i'm trying to do the following:

List<List<T^>^> test;

But doing: test[0][0] doesn't seem to work at all, like it's not designed for bi-dimensional arrays. Could someone know what am i doing wrong?

This is Windows Forms and i'm forced to use managed structures.

This worked for me: -

        Generic::List<String^>^ normalList = gcnew Generic::List<String^>();

        Generic::List<Generic::List<String^>^>^ TwoDList = gcnew Generic::List<Generic::List<String^>^>();

        TwoDList->Add(gcnew Generic::List<String^>());
        TwoDList->Add(gcnew Generic::List<String^>());

        TwoDList[0]->Add("First List - First Entry");
        TwoDList[0]->Add("First List - Second Entry");
        TwoDList[0]->Add("First List - Third Entry");

        TwoDList[1]->Add("Second List - First Entry");
        TwoDList[1]->Add("Second List - Second Entry");

        String^ sTest = gcnew String(TwoDList[0][1]);

        Trace::WriteLine(sTest);

My output window data was: -

First List - Second Entry
