Boxing and unboxing operations can have a negative impact on performance in certain scenarios. Let's understand what boxing and unboxing are before discussing their performance implications:
Boxing: Boxing is the process of converting a value type (such as int, float, etc.) to an object type (such as System.Object) by wrapping the value inside an object. This allows value types to be treated as objects and participate in operations that require object types, such as storing them in collections like ArrayList or passing them as parameters to methods that accept objects.
Unboxing: Unboxing is the reverse process of boxing. It involves extracting the value type from an object type and assigning it to a variable of the corresponding value type.
Remember
- No, it is recommended to use boxing and unboxing when it is necessary only.
- Converting from one type to another type is not good from performance point of view.
