C# uses delegates, instead. Similar functionality Not as ugly to 
declare. Function pointer syntax can get ugly.

Again, very similar to the predicates used in C#'s extension functions, 
which take delegates.

Which is essentially a delegate :)

I was mainly alluding to the messiness of declaring function pointers. 
C# does have a mechanism to do what you've described, though.
