Boxing And Unboxing In C#

In a sentence, Boxing is the process of converting value type to reference type.

Ex

int i=6; // Integer ‘i' is value type  
Object o = i; // Object ‘o’ is reference type   

Unboxing is the reverse process of the boxing like converting reference type to value type.

Object o = 6; // Object ‘o’ is reference type  
Int i= (int)o; // Integer ‘i' is value type  

Now here the another question in mind,

• What is Value and Reference type?
• What all are the value type and reference types?

Now start with:

What is Value and Reference type?

Value and Reference type are the two data types in c#.

Value type

Those variable which can contain the data directly that all falls in value type data type. As above example,

int i=6;  

Here we are assigning the value directly to the variable.

Object o = 6;
