In functional programming, we use them in variables, we store functions in dictionaries and collections, we work with them as parameters into a function, we can even create higher order functions that return a function from the method call. In C Sharp, there are three main ways of representing functions. Methods, delegates, and Lambda expressions. Of these three, the delegate and the Lambda expression are the most useful in functional programming. Delegates have been around forever in dot net. In recent years, Microsoft has created a number of generalized delegates that are useful, so you typically don't have to create your own custom delegates anymore.
