Boxing and unboxing are important concepts in C# that allow developers to convert .NET data types from value type to reference type and vice versa.
-
Boxing: This is the process of converting a value type to the object type or any interface type implemented by this value type. Boxing is implicit, meaning it happens automatically. When a value type is boxed, the common language runtime (CLR) wraps the value inside a System.Object instance and stores it on the managed heap.
-
Unboxing: This is the reverse of boxing, and it is the process of converting a reference type to a value type. Unboxing is explicit, meaning it requires a cast. Unboxing extracts the value type from the object.
Boxing and unboxing enable a unified view of the type system in which a value of any type can be treated as an object. However, they are computationally expensive processes, especially when dealing with simple assignments.
In summary, boxing and unboxing are important concepts in C# that allow developers to convert value types to reference types and vice versa. They enable a unified view of the type system, but they can be computationally expensive.
