Boxing and Unboxing

Conversion of the value type to the reference type is known as boxing - implicit

V > O 

int v = 1; object o = v;

Converting the reference type back to the value type is known as unboxing - explicit

O > V

object o = 5; int v = (int) o;

CLR boxes a value type, it wraps the value inside a System.Object instance and stores it on the managed heap.
