                  问题描述

                  我正在尝试将列表框 1 中的选定项目移动到列表框 2,反之亦然.我有两个按钮,>><<.当我选择 listbox1 中的项目然后单击 >> 时,项目应该从 listbox1 移动到 listbox2.

                  I'm trying to move selected items in list box1 to list box2, and vice versa. I have two buttons, >> and <<. When I select items in listbox1 and then click on >> the items should move from listbox1 to listbox2.

                  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]);
                      }
                  }
                  
                  private void button2_Click_1(object sender, EventArgs e)
                  {
                      MoveListBoxItems(listbox , lstActivity);
                  }
                  

                  推荐答案

                  您的代码运行良好.我测试了它.您的问题是我尝试将列表框 1 中的 选定 项移动到列表框 2."

                  your code works fine. i tested it. your question is "I try to move selected item in list box1 to list box2."

                  我认为你的 button2 有问题.删除 button2 和下面的代码

                  i think your button2 has problem.delete button2 and the code below

                  private void button2_Click_1(object sender, EventArgs e)
                  {
                      MoveListBoxItems(listbox , lstActivity);
                  }
                  

                  然后创建其他按钮并创建点击事件.

                  then create other button and create click event.

                  完整来源:

                  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]);
                      }
                  }
                  
                  private void first2second_Click(object sender, EventArgs e)
                  {
                      MoveListBoxItems(FirstListbox, LastListbox);
                  }
                  
                  private void second2first_Click(object sender, EventArgs e)
                  {
                      MoveListBoxItems(LastListbox, FirstListbox);
                  }
                  

                  此代码有效.如果要选择多个项目更改属性SelectionMode = MultiSimple;

                  this code is work. if you want select more than one item change property SelectionMode = MultiSimple;
