using IEnumerator to removing items
-
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!. _____________________________ ...and justice for all APe -

Check out ArrayList.Remove(). I think that will do the job for you. Cheers, Vikram.

Yeah!! something like this:
int iIndex = 0; while( iIndex < arrayList.Count) { if( //you need to remove this item) { arrayList.RemoveAt( iIndex); } else { iIndex++; } }_____________________________ ...and justice for all APe -

This requirement cannot be achieved using an foreach statement. So, I think you would need to use the 'FOR' loop, as follows:
for (int i = testList.Count-1; i >= 0; i--) { if(CONDITION is TRUE) { testList.RemoveAt(i); } }Regards, vinSharp There are two types of fools in this world: One who give advice and the others who do not take it...:laugh:
