Definition of Boxing and Unboxing:

In a garbage-collected heap, boxing is employed to store value types. A value type’s implicit conversion to the type object or any interface type provided by this value type is called boxing. When a value type is boxed, an object instance is created on the heap, and the value is copied into it.

A direct command from a type object to a value type or from an interface type to a value type tool is the interface known as unboxing. The following are the steps involved in an unpacking operation:

• Ensure that the object instance is a boxed value of the definite value type.
• The instance’s value is copied into the value-type variable.

The type system in C# has a concept called boxing and unpacking. By allowing any value of a value-type to be transformed to and from type object using boxing and unpacking, one can connect between value-types and reference-types. Boxing and unpacking allow for a unified view of the type system, allowing any type value to be handled as an object in the end.

ValueTypes must occasionally be converted to Reference Types, referred to as boxing. “Implicit boxing” means that you don’t have to explicitly tell the compiler that you’re boxing an Int32 to an object since it does it for you.

Boxing is the conversion of a value type to an object type, whereas Unboxing converts an object type to a value type. Let’s take a look at the other distinctions between Boxing and Unboxing.

• A value type is designed to refer to an object in boxing. The process of recovering the value from a boxed object, on the other hand, is known as unpacking.
• A stack value type is copied to a heap memory object. On the other hand, Unboxing involves copying a heap memory object to a stack memory value type.
• The difference between boxing and unpacking is that boxing is implicit, and Unboxing is explicit.
