ListViewItem item = yourListView.Items[yourListView.SelectedIndex];
//fill the text boxes
textBoxID.Text = item.Text;
textBoxName.Text = item.SubItems[0].Text;

ListView doesn't have property SelectedIndex. You should use SelectedItemsor SelectedIndices.
ListView 没有属性SelectedIndex。您应该使用SelectedItems或SelectedIndices。
So you can use this:
所以你可以使用这个：
private void yourListView_SelectedIndexChanged(object sender, EventArgs e)
{
if (yourListView.SelectedItems.Count == 0)
return;
ListViewItem item = yourListView.SelectedItems[0];
//fill the text boxes
textBoxID.Text = item.Text;
textBoxName.Text = item.SubItems[0].Text;
textBoxPhone.Text = item.SubItems[1].Text;
textBoxLevel.Text = item.SubItems[2].Text;
}
I suggested here that property MultiSelectis set to false.
我在这里建议将属性MultiSelect设置为false.
