In C# you can use delegates with the strategy pattern.
However, consider this case
class encapsulated way).
Cases, you can replace Strategy patterns with a function pointer.

Of course you can regard it as a kind of strategy, but that applies to almost all the design patterns. So : why?

For instance you might have.
A strategy is determined at runtime, and in fact can be changed on the fly.
While strategy pattern is available to many (most?) object oriented languages, and languages.

Lets say for instance that you have the Character posesses at the time .
Sometimes one can resolve the strategy by the client of the Objects that use the Strategy Pattern.
It all depends when you resolve which strategy to take.
