如何在xamarin表单中使用集合视图添加2行不同的图像

<CollectionView ItemsSource="{Binding ImageCollection}">
    <CollectionView.ItemTemplate>
        <DataTemplate>
            <Image Source="{Binding ImagePath}" />
        </DataTemplate>
    </CollectionView.ItemTemplate>
</CollectionView>

public class ImageItem
{
    public string ImagePath { get; set; }
}

public class ViewModel
{
    public ObservableCollection<ImageItem> ImageCollection { get; set; }

    public ViewModel()
    {
        ImageCollection = new ObservableCollection<ImageItem>();
        ImageCollection.Add(new ImageItem { ImagePath = "image1.png" });
        ImageCollection.Add(new ImageItem { ImagePath = "image2.png" });
    }
}

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        BindingContext = new ViewModel();
    }
}
