How do i read a base64 image in WPF?

Question

I know how to do it in WinForms

byte[] binaryData = Convert.FromBase64String(bgImage64);
image = Image.FromStream(new MemoryStream(binaryData));

In a situation I came across, I created a converter to handle the conversion of a Base64 string to WPF Image. So you can bind it to your base64 string property and let the converter handle the rest.

   public class ByteToImageConverter : IValueConverter
        {
            public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
            {
                if(string.IsNullOrEmpty(value.ToString())return;
                var imgBytes = Convert.FromBase64String(value.ToString());
                if (imgBytes == null)
                    return null;
                using (var stream = new MemoryStream(imgBytes))
                {
                    return BitmapFrame.Create(stream,
                        BitmapCreateOptions.None, BitmapCacheOption.OnLoad);
                }
            }

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