asynchronous programming c#

Opening I because of the love of network programming, regular use of C # to write various types of servers (e.g TCP server, UDP server), but basically are engaged in play, there are a lot of web-based C # network programming articles, of course, I also refer to a lot of authors write articles. After reading this articl

The BeginInvoke implementation of the delegate is asynchronoususingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Threading.Tasks;usingSystem.Threading;namespaceconsoleapplication1{ Public Delegate intMyDelegate (intx); classProgram {Static voidMain (string[] args) {MyDelegate del=NewMyDelegate ((a) ={Console.WriteLine ("Sub Thread Begin"); Thread.Sleep ( -); return 1; }); //delegate's BeginInvoke method implements

When we handle some long line calls, often causes the interface to stop responding or the IIS thread takes up too many issues, this time we need more asynchronous programming to fix these problems, but usually it is easier said than done, it is true that asynchronous programming is a completely different

a reference to the IAsyncResult interface of the asynchronous method that just ended, remember that the IAsyncResult interface object is inside the AsyncResult class object.2) Although the IAsyncResult interface does not have a reference to a delegate object, the AsyncResult class object that contains it has a reference to the delegate object.3) with a reference to the class object, we can now invoke the AsyncDelegate property of the class object and

C #~ Asynchronous programming continues ~ W3wp.exe caused by awaitand asynccrashes, This has recently started to happen again. The application pool of IIS is not suspended and all points to the same finger, async, threadPool, Task, and System. nullReferenceException makes us feel that our asynchronous program has a pro

There is nothing to do when I leave home, so I will take this opportunity to summarize the asynchronous programming technology to share with you. 1. What is a process? What is thread? Process: A process is a group of resources that constitute a running program. These resources include virtual address spaces, file handles, and carriers of other things required for program startup. When we start a program, th

C + + Concurrent programming asynchronous task asynchronous task Std::async(1) Std::async returns a Std::future object that holds the final computed result. When this value is required, only the Get () member function of the calling object is required. And the thread will not block until the expected state is ready; Af

The event-based asynchronous Pattern is a more advanced asynchronous programming model than the IAsyncResult pattern, and is also used in more contexts. For relatively simple applications that can be conveniently implemented directly with the new BackgroundWorker component of. Net 2.0, For more complex asynchronous app
