WPF:将同一图像绑定到DataGrid中的多个行(提高性能)

public class ImageModel : INotifyPropertyChanged
{
    private string imagePath;
    public string ImagePath
    {
        get { return imagePath; }
        set
        {
            imagePath = value;
            OnPropertyChanged(nameof(ImagePath));
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

public class ViewModel
{
    public ObservableCollection<ImageModel> Images { get; set; }

    public ViewModel()
    {
        Images = new ObservableCollection<ImageModel>();
        // 添加多个ImageModel对象到Images集合中
    }
}

<DataGrid ItemsSource="{Binding Images}">
    <DataGrid.Columns>
        <DataGridTemplateColumn Header="Image">
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <Image Source="{Binding ImagePath}" Width="50" Height="50"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>
