IEnumerable to Listview

Question

I want to write a method to filter a listview

IEnumerable<ListViewItem> CurrentList;
CurrentList = ListViewExemple.Items.Cast<ListViewItem>(); 
var result = CurrentList.Select(i => i.Text.Contains(SearchTxtBox.Text));

Now How can i add the "result" items to a cleared Listview

You'll have to keep in mind that a ListViewItem has an owner, you need to make a copy of the item to put it in another listview. Easy to do with its Clone() method. Or move it from one to the other, not likely in this case. So you probably want this:

    var matches = listView1.Items.Cast<ListViewItem>()
                  .Select(item => (ListViewItem)item.Clone())
                  .Where(item => item.Text.Contains(SearchTxtBox.Text));
    listView2.Items.Clear();
    listView2.Items.AddRange(matches.ToArray());
