关于SelectedItems.SubItems 的一个问题

Question

代码如下  想要实现的功能是 点击 listview 任意一行 数据 显示在 下边的 文本框里！！
 private void listView1_SelectedIndexChanged(object sender, EventArgs e)
        {
            if (listView1.Items.Count>0)
            {
                this.textBox1.Text = listView1.SelectedItems[0].SubItems[0].Text;
                this.textBox2.Text = listView1.SelectedItems[0].SubItems[1].Text;
                this.textBox3.Text = listView1.SelectedItems[0].SubItems[2].Text;
                
            }
         }
 运行报错 InvalidArgument=“0”的值对于“index”无效。
参数名: index
