                  问题描述

                  而不是像这样将字符串数组 m_List 中的每一项添加到 ListBox destinationList 中:

                  Instead of adding each item one by one to the ListBox destinationList from the string array m_List like this:

                  foreach (object name in m_List)
                  {
                      destinationList.Items.Add((string)name);
                  }
                  

                  有没有更好的办法?

                  我不想将数据绑定到destinationList,因为我想稍后从ListBox中删除一些条目.

                  I don't want to bind the data to the destinationList since I want to delete some entries from the ListBox later on.

                  推荐答案

                  HTH:

                      string[] list = new string[] { "1", "2", "3" };
                  
                      ObservableCollection<string> oList;
                      oList = new System.Collections.ObjectModel.ObservableCollection<string>(list);
                      listBox1.DataContext = oList;
                  
                      Binding binding = new Binding();
                      listBox1.SetBinding(ListBox.ItemsSourceProperty, binding);
                  
                      (listBox1.ItemsSource as ObservableCollection<string>).RemoveAt(0);
                  

                  只需使用 (ItemSource as ObservableCollection)... 来处理项目,而不是 Items.Add 等.

                  Just use (ItemSource as ObservableCollection)... to work with items, and not Items.Add etc.
