WPF中将指纹字节数组转换为Imagesource

using System.IO;

// 将指纹字节数组转换为Bitmap对象
public Bitmap ByteArrayToBitmap(byte[] byteArray)
{
    using (MemoryStream stream = new MemoryStream(byteArray))
    {

    }
}

        hBitmap,
        IntPtr.Zero,
        System.Windows.Int32Rect.Empty,
        BitmapSizeOptions.FromEmptyOptions());
    bitmapSource.Freeze();
    return bitmapSource;
}

using System.Windows.Media;

// 将BitmapSource对象转换为ImageSource对象
public ImageSource BitmapSourceToImageSource(BitmapSource bitmapSource)
