What is the difference between boxing and unboxing?
Answer:
Boxing is the process of converting a value type to the type object, and unboxing is extracting the value type from the object. While the boxing is implicit, unboxing is explicit.
Example (written in C#):
int i = 13;
object myObject = i; // boxing
i = (int)myObject; // unboxing
Example (written in C#):
int i = 13;
object myObject = i; // boxing
i = (int)myObject; // unboxing
