using IEnumerator to removing items

[d00_ape]

I want to remove some items from an ArrayList. Can I do that using a foreach(…)- loop an IEnumerator like this.

foreach(string s in arraylist)
{
    if (s == “del”)
    {
        // Here I want to remove the item from arraylist…
    }
}

Any ideas how to solve this without creating a new ArrayList and add items I want to save. Feels like that solution will bee to time consuming…

All tips are welcomed!.
