list_view_SelectedIndexChanged和list_box_SelectedIndexChanged之间的类比

Question

我有list_box的处理程序：

private void list_answers_SelectedIndexChanged(object sender, EventArgs e)
        {
            for (int i = 0; i < tasks.Count; i++)
            {
                if (list_answers.Text == "Question №" + (i + 1))
                {
                    this.ShowOnePanel(i);
                    iter = i;
                    break;
                }
            }
        }

和list_view：

private void list_answers_SelectedIndexChanged(object sender, EventArgs e)
        {
            for (int i = 0; i < tasks.Count; i++)
            {
                if (list_answers.Items[i].Text == "Question №" + (i + 1))
                {
                    this.ShowOnePanel(i);
                    iter = i;
                    break;
                }
            }
        }

适用于列表框，但不适用于listview。为什么？ 附： ShowOnePanel是我的方法，它显示了一个有疑问的小组。

Answer 1

if (list_answers.Items[i].Text == "Питання №" + (i + 1))

我猜它"question"不是"Питання"

修改

private void list_answers_SelectedIndexChanged(object sender, EventArgs e)
        {
            for (int i = 0; i < tasks.Count; i++)
            {
                if (list_answers.Items[i].Selected == true) // find selected item

                {
                    if (list_answers.Items[i].Text == "Question №" + (i + 1)) // check it's content
                    this.ShowOnePanel(i);
                    iter = i;
                    break;
                }
            }
    }
