    You have to show more research effort on your part. You should also post your non working code, instead of just saying that you got an exception.

    Is your application a winform or webform?

    System.Windows.Forms.ListView has 6 overloads in its Items collection’s Add method, here’s three:

     listView1.Items.Add(new ListViewItem("new item"));
 listView1.Items.Add("List item text", 3);  // Adds a new item with ImageIndex 3
 listView1.Items.Add("string");

    Try them out.

    System.Web.UI.WebControls.ListView has one way to call its Items collection’s Add method:

     ListView1.Items.Add(ListViewDataItem item);
