Foreach backwards for listboxes?

Question

foreach (ListViewItem lvi in listView1.SelectedItems)
{ 
   lvi.index;
}

This foreaches for all selected items, but how do i do this backwards?

Like first index 3 then 2 then 1.

Thankyou!

are you familiar with the term called `Reverse` you can't just do a quick google search..? what have you tried ? — MethodMan, Nov 03 '15 at 21:16
This is not a duplicate, as SelectedItems does not implement `IEnumerable`, only IEnumerable. — Eric J., Nov 03 '15 at 21:24

foreach (ListViewItem lvi in istView1.SelectedItems.Cast<ListViewItem>().AsEnumerable().Reverse());

Why do you have to explicitly cast and call AsEnumerable()? – Eric J. Nov 03 '15 at 21:21
Yup .AsEnumerable() is not needed :) – thekguy Nov 03 '15 at 21:22
because `SelectedItems does not implement generic IEnumerable` – MethodMan Nov 03 '15 at 21:23
And so the "closed as" duplicate is not exactly a duplicate. – Eric J. Nov 03 '15 at 21:23
@EricJ. notice how I am using the `Cast` taken from reading the MSDN https://msdn.microsoft.com/en-us/library/system.windows.forms.listview.selectedlistviewitemcollection(v=vs.110).aspx – MethodMan Nov 03 '15 at 21:25
Yep I vaguely recalled the need for it when working with pre-generic collections but did not recall the details. – Eric J. Nov 03 '15 at 21:45

You need to use for to iterate over the available indexes

for (int i = (listView1.Items.Count - 1); i == 0; i--)
{
    // i is the index
}
