My given code has an error of type conversion:

                byte?[] AibAttachment = null; 
                MemoryStream target = new MemoryStream();
                file.InputStream.CopyTo(target);
                AibAttachment = target.ToArray();
           

In above code AibAttachment = target.ToArray(); this line is throwing an error like "Cannot implicitly convert 'byte[]' to 'byte?[]'"

Please help me on this.

Maybe you can do something like this:

AibAttachment = Array.ConvertAll(target.ToArray(), i => (byte?)i);
