listView1.Items.Clear();

    private void button9_Click(object sender, EventArgs e)
    {
        listView1.Clear();
        listView1.Items.Add(\"Item1\");
        listView1.Items.Add(\"Item2\");
        listView1.Items.Add(\"Item3\");
        listView1.Items.Add(\"Item4\");
        listView1.Items.Add(\"Item5\");
    }

ListView lv = new ListView();
while (lv.Items.Count > 1) {
    //leave the header
    lv.Items.RemoveAt(1);
}

listView1.Items.Clear();

private void ClearLvItems(ListView li)
{
   while(li.Items.Count>1)
      li.Items.RemoveAt(1); 
}

 listView1.Items.Clear();
 SetHeaders(li); // If you have more then one ListView in the same form. Otherwise don\'t use the parameters.

 private void SetHeader(ListView li)
 {
   string[] header_names = new string[] {\"Id\",\"Name\",\"SurName\",\"Birth Date\"};
    int i = 0;
    foreach (ColumnHeader ch in li.Columns) 
    {
        ch.Text = header_names[i];
        ++i;
    }
 }

    foreach (ListView item in listview.Items)
    {
        ListView.Items.Remove(item);
    }

    ListView.Clear();

listview.Items.Clear();
