Simple Way to define Boxing and UnBoxing?

Submit Blog | Blogs Home |

Boxing:

   1) Converting the value type to the object type ( means to say it gets the value from the value type and stores it in the managed heap.

   2) is Implicit

eg:

int i = 77;

object obj = i;  /* It can simply assign to the type object in boixing and in technical term it boxes i */

UnBoxing:

   1) Converting the value from the object type to the value type (extracting the value and assigned to the value type)

   2) is Explicit

eg:

object obj = 70;

int i = (int) obj; /* unboxing the value wrapped inside the object type obj */
