How to Serialize an Image to a File

Question

0.00/5 (No votes)

I need to get an image from the system clipboard (Clipboard.GetImage()) and serialize it to a file. The end goal would be to, at a later time, deserialize this image and put it back in the clipboard.

I can't figure out how to successfully serialize the image. I tried creating a serializeable class that contains an image object, but I get the exception

"The type System.Drawing.Bitmap was not expected. Use the XmlInclude or SoapInclude attribute to specify types that are not known statically."

I tried using XmlInclude but am either doing it wrong or it does not resolve the problem.

Has someone done this before?

Why do you need to serialize it? Why can't you just use the Image.Save Method?

unless there is additional information that you need to save along with the image there is no need for serializing it .. with that said if you happen to desperately serialize it, first read it in a byte array and use the byte array in your serializable class.

Image img = Clipboard.GetImage();
            MemoryStream ms = new MemoryStream();
            img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
            byte[] imgByteArray= ms.ToArray();

hope this helps
good luck

If you want to Serialize a Bitmap, then do nothing!
It is already serialized! In memory and on disk.
Just do what the other told you. Save it on disk as it is.
And if you insist in making an ISerializable class, when there is no need to, I will start suspecting... "homework".
