What is boxing and unboxing in C#?

Can you explain what boxing and unboxing are in C#?

Sure! Boxing is the process of converting a value type to an object type, while unboxing is the reverse.

Can you give me an example of boxing in C#?

Of course! For instance, if you have an integer and you assign it to an object, that's boxing. Like this: object obj = 5;.

And how does unboxing work?

Unboxing retrieves the value type from the object. For example: int num = (int)obj; will unbox the integer from obj.

Are there any performance implications of boxing and unboxing?

Yes, boxing and unboxing can impact performance due to additional memory allocation and type conversion overhead.
