Answer / kirti

Boxing:

The conversion of a value type instance to an object, which implies that the instance will carry full type information at run time and will be allocated in the heap. The Microsoft intermediate language (MSIL) instruction set's box instruction converts a value type to an object by making a copy of the value type and embedding it in a newly allocated object.

Un-Boxing:

The conversion of an object instance to a value type.

Answer / kirti

Boxing :- Boxing is an implicit conversion of a value type to the type object type

Eg:-

Consider the following declaration of a value-type variable:

int i = 123;

object o = (object) i;

Boxing Conversion

UnBoxing :- Unboxing is an explicit conversion from the type object to a value type

Eg:

int i = 123; // A value type

object box = i; // Boxing

int j = (int)box; // Unboxing
