What is C# boxing?
Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. When the common language runtime (CLR) boxes a value type, it wraps the value inside a System. Object instance and stores it on the managed heap. Unboxing extracts the value type from the object.
Why is boxing and unboxing used?
