WebApr 19, 2012 · I am creating a generic operator method that can dynamically compare two objects of any type. For example: Object a = (int)5; Object b = (long)7; return a < b; Now this obviously won't compile because object does not provide the less than operator. Casting the objects back to their respective types would obviously work.
