提示说是“object”并不包含“text”的定义，怎么修改？

Question

private void upmovie_Click(object sender, EventArgs e )
{
int index = -1;
object it = new object(listBox1.SelectedItem.Text, listBox1.SelectedValue);

listBox1.Items[listBox1.SelectedIndex].Text = listBox1.Items[listBox1.SelectedIndex + index].Text;

listBox1.Items[listBox1.SelectedIndex].Value = listBox1.Items[listBox1.SelectedIndex + index].Value;

listBox1.Items[listBox1.SelectedIndex].Text = it.Text;

listBox1.Items[listBox1.SelectedIndex].Value = it.Value;

listBox1.Items[listBox1.SelectedIndex].Value = it.Value;
}

Answer 1

object it = new object(listBox1.SelectedItem.Text, listBox1.SelectedValue);

->

ListBox it =(ListBox)Sender;
