What is boxing?..

Answer / maloy.adhikari

Boxing is the process of converting a value type to the
type object or to any interface type implemented by this
value type. When the CLR boxes a value type, it wraps the
value inside a System.Object and stores it on the managed
heap. Unboxing extracts the value type from the object. In
the following example, the integer variable i is boxed and
assigned to object o.
Exam::
int i = 123;
object o = (object)i; // boxing
...........
o = 123;
i = (int)o; // unboxing
