Using foreach with an ArrayList

hi. I'm trying to use the foreach statement with the ArrayList. Here is a sample of my code:

ArrayList AList = new ArrayList();

AList.Add("hi");
AList.Add("ko");
AList.Add("dr");
AList.Add("cvdf");

foreach(int x in AList)
{
// some code

}

I'm getting an invalid cast exception. Anyone knows why? - Jennifer

Here is a very interesting article on using (actually, NOT using) foreach.

The primary reason for your 'invalid cast' error is that you are inserting string objects eg. AList.Add("dr");, but then using 'int x' as the type of objects you want to search.

Change it to:
foreach(String x in AList)
{
//some code
}

This should work.

Hope this helps!
