How to make bidimensional arrays with a List?
0
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.
winforms list c++-cli

test[0][0] is correct syntax. You probably did not initialize the list correctly. Don't forget that you have to create a List for each element in the outer List. Copy/paste the compile error or exception if you still have trouble.

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
