Serialization of an Int16 returning 52bytes????

I am currently trying to serialize a custom class however I am getting a much larger Byte array than i would expect. In an effort to diagnose the issue I replaced my class with an Int16 object. I would expect the oMemStream.ToArray() to return a byte array of length 2. based on the int16 abc having a value of 0x0706. Instead i am recieving a byte array of length 52.

Can anyone explain how and why i am getting so much data, and two how to get the byte array that actually represents the value of this int16 in such a way that i can apply that knowledge to my custom class.

Thank you.

Int16 abc = 0x0706;
            try
            {
                MemoryStream oMemStream = new MemoryStream();
                BinaryFormatter oBinaryFormatter = new BinaryFormatter();
                oBinaryFormatter.Serialize(oMemStream, abc);
                Byte[] oCommMessage = oMemStream.ToArray();
                oMemStream.Close();
                
            }
            catch { MessageBox.Show("Error Seralizing ABxCmdMessage"); }
 
            return msgStatus;
