| How to make a Sum of listBox items?

Assuming all the items in the listbox are string representations of integers
:

{
int total = 0;

foreach (object o in listbox1.Items)
{
total += (int) Convert.ChangeType(o, typeof(int));
}
}

Or just simply:

int count = listbox.Items.Count;

Cheers

Huh ? The term Sum means the total of all the values, not the Count.

Well it depends on context

If I asked for the sum total of items in the list I'd probably be after the
count. but if I asked for the sum of the items I'd probablt be asking got
the the sum across each item in teh list.

The problme is that on an English newsgroup in a heavily non-English
speaking world then both interpretations are valid and the OP needs to
provide more context.
