C# listview select row(a row and multiple rows)

The listview control can be used to display a menu or a table. When used to display a table, you can select a row or multiple rows; it provides the corresponding properties, you only need to set the corresponding properties to true; you can set it in the control properties or use a sentence code.

              //Get the value of the second column of the selected row
                     string colunmVal2 = listview1.SelectedItems[0].SubItems[2].Text;

              //Get the value when multiple rows are selected
                     foreach (ListViewItem lvi in listView1.SelectedItems)
                     {
                            string colunmVal1 = lvi.SubItems[0].Text);
                            string colunmVal2 = lvi.SubItems[1].Text);
