Delegate, Lambda expression, and event series 06. Use Action to implement observer mode and experience the difference between delegate and event. lambdaaction In "two ways to implement the Observer Pattern", the Observer Pattern has been implemented through the interface, delegate, and event methods. This article uses Action to implement this mode and to experien

The essence of the chain is that you put a bunch of things to execute in a list, when you want to trigger a set of things, you do not need to write one by one (such as the factory canteen dinner, this method is implemented, to let the chef a time in the cafeteria waiting to play rice, b staff at a certain time line, b staff may more than one , should be notified that Class C staff at another time in line to eat, the last Class D cleaners at another time to clean up the canteen), below you only n

Delegate (dekegate) is a type of dynamic invocation method that is the same as a class, interface, and array, and is a reference type that can be used to implement multicast (MulticastDelegate). Multicast (multicastdelegate): You can use " +" "-" to Merge and remove multiple delegate objects, you can use "+ =" to add a delegate object,"-=" Remove the

For more information about this section, see. NET and C # advanced programming (version 4). 1. Understand Delegation We know that a callback function is actually a pointer to a method call, that is, a function pointer. In. net, the function pointer concept is implemented in delegate mode .. The main reason for using delegation in. NET is that it is of type security. Why? In the past, for example, in C, the function pointer was just a pointer to a sto

Delegates are also called delegates , representing a class of methods. This class of methods has the same modifiers, formal parameters, and return value types .1. The delegate is both a method and a delegate is declared as follows: Add the delegate [' d?l?ɡ?t] keyword after the modifier1 Public Delegate void Del (stri

Objective Previous C # using attribute to implement AOP transactions [C # | AOP | Attribute | ContextAttribute | Icontributeobjectsink | IMessageSink] is a way to achieve or to achieve an AOP effect, in fact, the earliest design in C # using AOP to complete the transaction plan is to use delegate, but not accustomed to use this thing, also understand not deep, later was attracted by attribute, The plan ran aground, but now I'm back: Body Let's take

In the previous blog, we introduced the logic control program of an automated system in the data center. Lambda expressions are used to facilitate the implementation of program functions. however, we should not only strive to implement functions and complete tasks. We should know what it means, that is, knowing Lambda expressions can bring such convenience, we should also know why it brings such convenience. Next, let's take a small journey with you.To find out why, we use Reflector to decompile

A delegate (delegate) is also called an agent, which is a common design pattern in iOS development. We can easily implement this design pattern with the help of Protocol (see Blog: Objective-c Protocol (Protocol)).What is an agent?Apple's official documentation gives a clear explanation:Delegation is a simple and powerful the pattern in which one object in a program acts on behalf of, or in coordination wit

Delegate, Lambda expression, event series 05, Action delegate and closure, lambdaaction Here is an example of using the Action delegate: static void Main(string[] args) { int i = 0; Action a = () => i++; a(); a(); Console.WriteLine(i); } The result is expected 2. But the curious thing i

Here is an example of using the action delegate: static void Main(string[] args) { int i = 0; Action a = () => i++; a(); a(); Console.WriteLine(i); } The result is expected 2. But the curious thing is: how is the variable I on the stack passed to the action delegate? Check the reverse compilation. First, check the Il code corresp

Sometimes, we want to call a delegate, but we can execute multiple methods at the same time (the most common in custom events), for example, a jobCompositionAfter the file is generated, the system will generate the document log and save it to the database. For the above two operations, if you only want to call one delegate, you can complete it in sequence, you can use multicast delegation. If you call mul

Question: The difference between delegate and delegateAnalysis:I believe many friends in the development process have encountered the above questions, in order to solve this question, recently consulted a lot of posts, and finally in the official MSDN document found the answer.Here are the official document link addresses for delegate and delegateDelegate: https://msdn.microsoft.com/zh-cn/library/ms173171.a

delegates and events are widely used in the. Net framework, however, a good understanding of delegates and events is not easy for many people who are not in touch with C # for a long time. They are like a sill, after the threshold of the people, it is very easy, and no past people every time to see the Commission and events feel in the heart to panic, uncomfortable. In this article, I'll go through two examples of what is a delegate, why I use delegat

By Lao Zhao (Zhao Yu, Network nameLao Zhao, Foreign nameJeffrey ZhaoHe is currently a researcher at the product development department of Shanda Innovation Institute .) In his article "feelings about recent interviews", Michael talked about his question about "How to Write delegate in. Net framework1.1, 2.0, and 3.5" during the interview. As a result, a friend replied, "I would like to ask the landlord, but there are several ways to write "and "Contem
