# The second option is to make a new, separate class and add a static method that takes an object of the class type and returns a new object with the modification of choice.

The first option is in principle easier, but it is unfortunately limited by the fact that many classes restrict inheritance of certain members or forbids it completely. This includes sealed class and the different primitive data types in C# such as [[Integer (computer science)|int]], [[Floating point|float]] and [[String (computer science)|string]]. The second option, on the other hand, does not share these restrictions, but it may be less intuitive as it requires a reference to a separate class instead of using the methods of the class in question directly.
As an example, consider a need of extending the string class with a new reverse method whose return value is a string with the characters in reversed order. Because the string class is a primitive type, the method would typically be added to a new utility class in a manner similar to the following:
