Cast ListView Items to List?

Question

How can I cast ListView.Items to a List?

This is what I tried:

List list = lvFiles.Items.Cast

A ListViewItemCollection is exactly what it sounds like - a collection of ListViewItem elements. It's not a collection of strings. Your code fails at execution time for the same reason that this code would fail at compile time:

ListViewItem item = lvFiles.Items[0];
string text = (string) item; // Invalid cast!

If you want a list of strings, each of which is taken from the Text property of a ListViewItem, you can do that easily:

List list = lvFiles.Items.Cast()
                                 .Select(item => item.Text)
                                 .ToList();
