I've got a method that returns an array of Ints. What's the most
sensible way of copying them to a new ArrayList?

Thanks!

Hi Jerry,
The ArrayList has a constructor that takes a collection as input.

int []items = {1,2,3,4,5};

ArrayList items2 = new ArrayList(items);

Hi

Thanks.

I thought I could do that, but its saying "Cannot implicitly convert
type 'int[]' to 'System.Collections.ArrayList'"

Any ideas where I might be going wrong?

Jerry

Hi

Ooops.

There was an extra "=" in my code.

Thanks.

It's now working!

First you should consider if you really need to make this copying, since an
array in itself implements the interfaces ICollection, IList and
IEnumerable.

If you then decide that you want to do this operation anyway, there are many
ways to do it, depending on what you mean by "copying".

int[] arrayOfInts;

// Some initializing and population of the array...

ArrayList myList = new ArrayList(arrayOfInts);

....is possibly the simplest way.
