这是个实用的小功能，在WEB开发时也经常会看到这种功能，将item数据项由左侧移动到右侧，这是一个选择+移动的功能，全部添加到选择的项中，判断是否已经选择了该菜单项，比如本例子利用左右移动SelectItem项实现了点菜功能： 　　private void button3_Click(object sender, EventArgs e)//移除所有已经选择的菜 　　{ 　　 lbChoose.Items.Clear(); 　　} 　　private void button1_Click(object sender, EventArgs e)//单个添加到选择的项中 　　{ 　　 if (lbSocure.SelectedIndex != -1) 　　 { 　　 if (!lbChoose.Items.Contains(lbSocure.Text))//判断是否已经选择了该菜 　　 lbChoose.Items.Add(lbSocure.SelectedItem.ToString());//添加选择的菜 　　 else 　　 MessageBox.Show("您已经选择了该菜，请重新选择。"); 　　 } 　　}
