Boxing and unboxing

---

SLIDE-1

• Boxing and unboxing in C# allows developers to convert .NET data types from value type to reference type and vice versa.

SLIDE-2

• Converting a value type to a reference type is called boxing in C#.

• Example:

     				public static void Main()
     					{
     				        int i = 2;  
     				        object o = i; // boxing  							       
     				        Console.WriteLine(i);
     					} 
  

SLIDE-3

• Converting a reference type to a value type is called unboxing in C#.

• Example:

     				public static void Main()
     					{
     				        int a = 10;  
     				        object objectOne = a; // boxing  
     				        int b = (int)objectOne; // unboxing  
     				        Console.WriteLine(b);
     					}
