  private void MoveListBoxItems(ListBox source, ListBox destination)
  {        
      ListBox.SelectedObjectCollection sourceItems = source.SelectedItems;
      foreach (var item in sourceItems)
      {
          destination.Items.Add(item);
      }
      while (source.SelectedItems.Count > 0)
      {
          source.Items.Remove(source.SelectedItems[0]);
      }
  }
  

  使用：在您从1到2按钮移动的点击事件中：

  MoveListBoxItems(listBox1, listBox2);
  

  要将它们移回：

  MoveListBoxItems(listBox2, listBox1);

  ListBox具有 SelectedItems 属性，您可以使用该属性来复制按钮的单击事件处理程序中的项目 . 像这样：

  foreach(var item in listBox1.SelectedItems)
  {
      listBox2.Items.Add(item);
  }

  private void Move(ListControl source, ListControl destination)
  {
         List<ListItem> remove = new List<ListItem>();
         foreach(var item in source.Items)
         {
              if(item.Selected == false) continue;
              destination.Items.Add(item);
              remove.Add(item);
         }
         foreach(var item in remove)
         {
              source.Items.Remove(item);
         }
  }
  

  然后你就可以这样称呼它

  Move(listbox1, listbox2);
  //or
  Move(listbox2, listbox1);
