如何使用值转换器将字节数组绑定到WPF中的图像？

using System;
using System.Windows.Data;
using System.Windows.Media.Imaging;

public class ByteArrayToImageConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null)
            return null;

        byte[] byteArray = value as byte[];
        BitmapImage bitmapImage = new BitmapImage();
        bitmapImage.BeginInit();
        bitmapImage.StreamSource = new MemoryStream(byteArray);
        bitmapImage.EndInit();

        return bitmapImage;
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

   <local:ByteArrayToImageConverter x:Key="ByteArrayToImageConverter" />
</Window.Resources>
