another idea is to have a helper class to do this by reflecting the object and extract its all data members and gather all fields size by sizeof() , it will be a little bit complicated but it is implementable
this class will calculate the actual size of an object , but i have tested it just a few times and a few objects were tested but i think i will be working.

private static int GetTypeSizeArray(string typeName, object objValue)

return sizeof(System.Double) * ((System.Double[]) objValue).Length ;
case "System.Single[]":
return sizeof(System.Single) * ((System.Single[])objValue).Length;
case "System.Char[]":
return sizeof(System.Char) * ((System.Char[])objValue).Length;
case "System.Int16[]":
return sizeof(System.Int16) * ((System.Int16[])objValue).Length;

return sizeof(System.Int32) * ((System.Int32[])objValue).Length;
