Hi friend,

First of all, u hav written wrong.
It is UnBoxing no InBoxing.

Lets see:

When u want to use a integer in any string or u want to convert any integer variable into string, U simply write

string s= 20.ToString();

This is called Boxing, means u hav a value type & u want a reference type then the Compiler create an object Box into which it places the value of value type.

eg.

int n=5;
//Create a box to hold the value of n
object obj=n;
//U know thar object is the datatype that can hold any data type

//Now u wnat to use ur integer value again, so u will unbox it
int m = (int)obj;

when u will do unboxing, Casting is must. If u will not do, thenm compiler will generate an error.

Regards,
Anuj Rathi

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. Boxing is implicit; unboxing is explicit. ... The following examples illustrate how boxing is used in C# 9apps
