用字符串数组填充 WPF 列表框

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.
