I am trying to determine how to write the camera serial number to a jpeg file using C#. I had thought that it would be case of setting an appropriate EXIF header value (and maybe it is), but when I open the image using C# + System.Drawing.Image.FromFile(…), the image.PropertyIdList array does not include an EXIF id which would seem to represent the serial number.

I then opened the file in Windows File Explorer, for the jpeg file, Properties, and Details, I see no value for “Camera Serial Number”.

I then used Windows File Explorer/Properties/Details to set the camera serial number to “hello”. This persists. However, when I load the image using C# again, I see the same list of Ids as before – ie. I don’t have a new one holding my “hello” serial number.

Is there a way, from C# code, that I can read/write the camera serial number ?

My code is very simple…

        static void Main(string[] args)
        {
            using (var image = System.Drawing.Image.FromFile(@"c:tempexample.jpeg"))
            {
                foreach (var propertyId in image.PropertyIdList)
                {
                    Console.WriteLine($"{propertyId:x}");
                    /*
10e     image description
10f     camera make
110     camera model
131     software name

                }
            }
        }

(the first 8 of which I wrote to the JPEG file when I saved it)
