A non-Action delegate could for example define at what speed you run and return the time it took to complete it. public delegate void MoveAction(); public delegate int MoveDelegate(int speed);
Also there are useful generic delegates which considers a return value: Converter<TInput, TOutput> (MSDN) Predicate<TInput> - always return bool (MSDN) Method: public MyType SimpleUsing.DoUsing<MyType>(Func<TInput, MyType> myTypeFactory) Generic delegate: Func<InputArgumentType, MyType> createInstance = db => return new MyType();
May 30, 2017 · If you know what parameter you want to pass, take a Action<T> for the type. Example: void LoopMethod (Action<int> code, int count) { for (int i = 0; i < count; i++) { code(i); } }

Jan 28, 2015 · One downside with the EventHandler design pattern is memory leaks. Also should be pointed out that there can be multiple Event Handlers but only one Action. @LukeTO'Brien: Events are in essence delegates, so the same memory leak possibilities exist with Action<T>. Also, an Action<T> can refer to several methods.
51. So when I write something like this. Action action = new Action(()=>_myMessage = "hello"); Refactor Pro! Highlights this as a redundant delegate creation and allows me to to shorten it to.

Func is a delegate (pointer) to a method, that takes zero, one or more input parameters, and returns a value (or reference).

Dec 1, 2018 · First way: Defining actions using strings like the following: const actionCreatorExample = (value) => {. return { type: 'SET_RESPONSE', value }; } Second way: Defining action types in an object and referring to action types by accessing the values of that object. Like this: export const actionTypes = {.
