                  问题描述

                  我的窗体包含两个列表框.Listbox1 中包含一些项目,而 listbox2 为空.当我按下表单上的按钮时,应将 listbox1 中的多个选定项目从 Listbox1 中删除并复制到 Listbox2.

                  My windows form contains two listboxes. Listbox1 contains some items in it and listbox2 is empty. When I press a button on the form, then multiple selected items from listbox1 should be removed from Listbox1 and copied to Listbox2.

                  我在 listbox1.SelectedItems 上尝试了 foreach 循环,但它只从列表中删除了一项.

                  I tried with foreach loop on listbox1.SelectedItems but it removes only 1 item from list.

                  有人有解决方案或代码吗?

                  Anyone has solution or code for this?

                  推荐答案

                  您可以在一个循环中完成所有操作.您应该在 SelectedIndices 上使用简单的 for 并向后循环:

                  You could do all in a single loop. You should use a simple for and loop backwards on SelectedIndices:

                  private void button1_Click(object sender, EventArgs e) 
                  { 
                      for(int x = listBox1.SelectedIndices.Count - 1; x>= 0; x--)
                      { 
                          int idx = listBox1.SelectedIndices[x];
                          listBox2.Items.Add(listBox1.Items[idx]); 
                          listBox1.Items.RemoveAt(idx);
                      } 
                  }
