Which is better CStringArray or CString concatenate with delimiter

[ABM]

Hi
i want to store all the elements of the list box, but i don't know what's the best way to store in the memory. Should i store in CStringArray or Concatenate all the elements of the listbox with a delimiter say comma and split to retrieve the elements. Please tell me which is the best way and which will take less memory.

Regards
Abhishek Madaan
