Boxing is converting a value type to reference type

Unboxing is an explicit operation.

Eg.

In C# :

int X=1;
Object Y;
int Z;

Y=X; -------------> This is BOXING
Z=(int)Y; ----------------> This is UNBOXING

Boxing is what happens when a value-type object is assigned to a reference-type variable.
Unboxing is what happens when a reference-type variable is assigned to a value-type variable.

Boxing is a process of converting value type into reference type while unboxing is vice versa

What happened in backend.

Value type is stored in Stacks
Reference type is stored in Heap

So boxing.

Values shifted Stacks to Heap and vice versa.

Boxing: Converting Value Type into Reference Type

Example:
 
int i = 10;

string str = Convert.ToString(i);

Unboxing: Converting Reference Type into Value Type

Example:

string str = "10";

int i = Convert.ToInt16(str) ;

Boxing permits any value type to be implicitly converted to type object or to any interface type implemented by value type.
Unboxing is vice verse of boxing operation where the value is copied from the instance into appropriate storage location.

EX:-
Dim X As Integer
Dim Y As Object

X=10<--BOXING PROCESS-->
Y=X<--UNBOXING PROCESS-->
