我需要在两个 ListBox 列中显示两个列表，但是通过 MVVM 模式它会是一行。我已经搜索了互联网，但还没有找到任何东西。我只是在学习，也许正因为如此我错过了一些东西，如果有人有机会解释，或者至少是某种例子，我会很高兴。

视图模型：

private List<string> _artists = new();
private List<string> _names = new();
private List<Song> _songs = new();

     public List<string> Artists
    { 
        get 
        { 
            return _artists; 
        } 
        set { _artists = value; OnProopertyChanged(); } 
    }

     public List<string> Names
    {
        get
        {
            return _names;
        }
        set { _names = value; OnProopertyChanged(); }
    }

     public List<Song> Songs
    {
        get
        {
            return _songs;
        }
        set { _songs = value; OnProopertyChanged(); }
    }

        for (int counterForList = 1; counterForList < 41; counterForList++)
        {
            HtmlMethod(counterForList,2, out Artist);
            HtmlMethod(counterForList,3, out Name);

            Song song = new Song(Name, Artist);
            Songs.Add(song);
        }

        foreach (var song in Songs)
        {
            Artists.Add(song.Artist);
            Names.Add(song.Name);
        }

模型：

public class Song
{
    public string Name { get; set; }
    public string Artist { get; set; }

和 MainWindow 本身：

<Window xmlns="https://github.com/avaloniaui"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:vm="using:AvaloniaApplication1.ViewModels"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="600" d:DesignHeight="350"
    x:Class="AvaloniaApplication1.Views.MainWindow"
    Icon="/Assets/avalonia-logo.ico"
    Title="AvaloniaApplication1"
    Width="600"
    Height="350"> 
    

<Design.DataContext>
    <vm:MainWindowViewModel/>
</Design.DataContext>
<Grid>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <TextBlock Text="{Binding Title}" HorizontalAlignment="Center" VerticalAlignment="Center" Grid.Column="1"/>
    <ListBox Items="{Binding Songs}" Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="3" Grid.RowSpan="2">
        <ListBox.ItemTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition/>
                    <ColumnDefinition/>
                </Grid.ColumnDefinitions>
            </Grid>
        </ListBox.ItemTemplate>
    </ListBox>
</Grid>

这里是代码，我不明白如何在不同的列中显示艺术家和名称，或者可以划分歌曲。在 avalonia 纪录片中写道，他们没有 ItemSource，他们只有一个 Item。
