Boxing and Unboxing

Question

Distinguish between Boxing and Unboxing.

Answer 1

Whenever a value type is transformed into an object type, the procedure is termed as boxing; on the other hand, whenever an object type is transformed to the value type, the method is termed as unboxing.
Boxing and unboxing permits the value types to be regarded as the objects. Boxing a value type packages it inside the sample of the Object reference type. This enables value type to be stored on the garbage collected heap. Unboxing extracts value type from an object. In the given example, the integer variable i is boxed and is assigned to the object obj.

Example:

int i = 123;

object obj = i;  /* Thi line boxes i. */

/* The object obj can be unboxed and then be assigned to integer variable i: */

i = (int)obj; // unboxing
