How to modify value in ArrayList?

[Guest]

Given:

ArrayList al=new ArrayList();
int i=1;
al.Add(i);

How can I change the value of al[0] to 2?
(without removing the object and then adding a new one)

This won't work, since int is an value type object:

int k=(int) al[0];
k=2; //(al[0] is not updated since k is a not a referrence to it

Is it possible?

You cannot modify the value without removing and readding it, since as you
already noticed it is a boxed value type.
