using Arrays with unknown size
Alan Glazer
To change the capacity of an array, you can write lots of code to re-allocate arrays with different sizes, but this has already been done for you.
If you don't know the capacity beforehand, the ArrayList is your best bet (with a slight performace panelty). The ArrayList dynamically resizes when you try to fill it up beyond its capacity.
To control the size, you can set the Capacity property, or use TrimToSize().

For ArrayList you don't need to know the size in advance. Just create an ArrayList and add items to it:
ArrayList list = new ArrayList();
list.Add("Hello");
list.Add("World");
list.Add("!");
