Finally what is that?!

[C# newbie]

Hi,

So far, I have found that ArrayList is a single dimension array and there is
no way we can use it terms of Multi-dimensional array.
Is this right or no ?

Eveybody says something different about this!!!

It is similar to a single dimensional array that can hold any object. If
each object happens to be an array (or another ArrayList), then effectively
you have a 2 dimensional array. And so on, you can have a multi-dimensional
array of any depth.

This is exactly the way regular object arrays work. Except that they cannot
grow and shrink dynamically.

Thanks Marina, so it means I can have an array or structure into an element
of the arraylist so contents of every element is different with other ones.

not really. that's not the same thing. that's an arraylist of arraylist, which is similar to a jagged-edge array [x][], but not the same thing as a multi-dimensional array [x,y

This is exactly the way regular object arrays work. Except that they canno
grow and shrink dynamically

again no. array[,] and array[][] are very different

As I said before. Eveybody says something different!

Hi,

and there
