Delegate:Delegate is a pointer to a method. Delegate can be passed as a parameter to a method.We can change the method implementation dynamically at run-time. Also we can use delegate in asynchronous programming. It has following flavors: Func - It takes params and perform actions. It always returns value. Action -It takes params and perform actions. No mandatory to return value. Predicate - It always returns boolean value. They are commonly used for iterating a collection or to verify if the value does already exist. Converter - It is used to mostly convert value from one entity type to another. Lets say you have employee collection and you want to convert it to XEmployee list. Comparison - It is used to sort the records in a collection. These are also called generic delegates because it uses generic types. http://www.codeproject.com/Articles/741064/Delegates-its-Modern-Flavors-Func-Action-Predicate
