C#，WPF绑定到ListBox的数组将不起作用

// 假设你有一个字符串数组
string[] items = { "Item1", "Item2", "Item3" };

// 在XAML中
<ListBox x:Name="myListBox" ItemsSource="{Binding items}"/>

// 在代码后面
myListBox.DataContext = this;

public partial class MainWindow : Window
{
    public string[] items { get; set; }

    public MainWindow()
    {
        InitializeComponent();
        items = new string[] { "Item1", "Item2", "Item3" };
        this.DataContext = this;
    }
}

<ListBox x:Name="myListBox" ItemsSource="{Binding items}"/>

public string[] items { get; set; }

public MainWindow()
{
    InitializeComponent();
    items = new string[] { "Item1", "Item2", "Item3" };
    this.DataContext = this;
}

// 使用ObservableCollection来代替数组
public ObservableCollection<string> items { get; set; }

public MainWindow()
{
    InitializeComponent();
    items = new ObservableCollection<string> { "Item1", "Item2", "Item3" };
    this.DataContext = this;
}

<!-- MainWindow.xaml -->
<Window x:Class="WpfApp.MainWindow"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <ListBox x:Name="myListBox" ItemsSource="{Binding items}"/>
    </Grid>
</Window>

// MainWindow.xaml.cs

namespace WpfApp
{
    public partial class MainWindow : Window
    {
        public ObservableCollection<string> items { get; set; }

        public MainWindow()
        {
            InitializeComponent();
            items = new ObservableCollection<string> { "Item1", "Item2", "Item3" };
            this.DataContext = this;
        }
    }
