我正在尝试将数据添加到多列列表框中，我做到了，但在尝试从列表框中检索数据时遇到了难题。有没有办法将对象而不是文本放入列表框行中？

<ListView Name="listBox1" ItemsSource="{Binding Items}" Margin="28,28,68,67" FlowDirection="RightToLeft" MouseDoubleClick="listBox1_MouseDoubleClick">
        <ListView Name="listBox1" ItemsSource="{Binding Items}" Margin="28,28,68,67" FlowDirection="RightToLeft" MouseDoubleClick="listBox1_MouseDoubleClick">
        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn Header="a" Width="100" DisplayMemberBinding="{Binding Path=ID}" />
                    <GridViewColumn Header="b" Width="100" DisplayMemberBinding="{Binding Path=Name}" />
                    <GridViewColumn Header="c" Width="100" DisplayMemberBinding="{Binding Path=F}" />
                </GridView.Columns>
            </GridView>
        </ListView.View>
    </ListView>
</Grid>

这是代码

 public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
    public sealed class MyListBoxItem
    {
        public string Field1 { get; set; }
        public string Field2 { get; set; }
        public string Field3 { get; set; }
    }

    private void Window_Loaded(object sender, RoutedEventArgs e)
    {
        Students st = new Students(1, "name","anything");
        listBox1.ItemsSource = new List(new[] { st });
    }

    private void listBox1_MouseDoubleClick(object sender, MouseButtonEventArgs e)
    {
        object ob = listBox1.SelectedItem;
        string i = ((MyListBoxItem)listBox1.SelectedItem).Field1;
    }
}

这是班级学生

 class Students
{
    int id;
    string name;
    string f;

    public Students(int id, string name,string f)
    {
        this.id = id;
        this.name = name;
        this.f = f;
    }
    public int ID
    {
        get { return id; }
        set { id = value; }
    }
    public string Name
    {
        get { return name; }
        set { name = value; }
    }
    public string F
    {
        get { return f; }
        set { f = value; }
    }
}

不要使用 listBox1.Items.Add(....)。而是使用 listBox1.ItemsSource = new List(new[] {st});

然后将您的 DisplayMemberBindings 分别更改为“Id”、“Name”。

不需要 ListBoxItem 类。

你已经非常接近完美了。我在下面附上了它应该如何工作。需要注意的重要事项是 ListView 中 ItemsSource 和 SelctedITem 的绑定，并将 IsSynchronizedWithCurrentItem 设置为 true。

另外，在网格的底部两行中，我展示了绑定到所选项目的两种不同方式，一种使用“/”表示法，另一种使用 ViewModel 上的属性
