Answer Posted / deepak
actually we need boxing and unboxing to keep more than one type of value type of variables in a common reference type of collection.. so that you can do the common operation in a loop or anywhere else.. by unboxing one by one.. also you can pass that collection to any method.. so you dont need to make many overloaded method for every type of value type..
