1. A delegate is a type safe function pointer. That is, they hold reference(Pointer) to a function. The signature of the delegate must match the signature of the function, the delegate points to, otherwise you get a compiler error. This is the reason delegates are called as type safe function pointers.
Advantages to using them in design:Allow you to develop libraries and classes that are easily extensible, since it provides an easy way to hook in other functionality (for example, a where clause in LINQ can use a delegate [Func<T,bool>] to filter on, without having to write new code in the Where method.
If you have an common use for your delegates, you should store them on a common place, but if you only use it in your class then put it in the same class. Show activity on this post. You don't have a Classes, Structs, and Enums folder.
Now that we have lambda expressions and anonymous methods in C#, I use delegates much more. In C# 1, where you always had to have a separate method to implement the logic, using a delegate often didn't make sense. These days I use delegates for:
