How prevent duplicate items listView C#

Question

I am using Windows Forms. With this code I add items to listView from comboBox.

ListViewItem lvi = new ListViewItem();         


        

Answer 1

if (!listView1.Items.Any(i => i.text == lvi.text))
{
    listView1.items.Add(lvi)
}

I'm just guessing on the text property, but I'm pretty sure that's there.

Alternatively - just have a List and use it as a data source for your list.
