asynchronous c#

Sanniusignal is a completely free DLL Based on asynchronous socket. It encapsulates client, server, and UDP. With this DLL, you do not need to worry about heartbeat. Stick the package.Group packages, sending files, and other complex tasks. You only need a few simple steps to implement a powerful communication system. It can help you feel the happiest thing and hope you canFind out the deficiencies in the DLL in the Process of use; make corrections; th

In this article we will take a big step forward by using the asynchronous way to program the server so that it becomes a truly servers: it can serve multiple requests to many clients. But before we begin, we need to address one of the remaining issues in the previous section. Issues when messages are sent The question is: When the client writes data to the stream two times (such as a string), we consider the two writes as two requests subjectively,

. Beginerrorreadline (); One process. WaitForExit (); A } - Catch(Exception e) - { the Console.WriteLine (ex. Message); -}It is important to note that asynchronous and synchronous read operations cannot be mixed with the same redirect stream.After you open the redirect stream for a Process in asynchronous or synchronous mode, all further read operations on the stream must be in the same mode.For example, do

. Both of these methods will block. If you want to avoid blocking, you can first use the Pending method to determine whether a connection request is available in the queue.Although the TcpListener has been packaged relatively good, we use it in the construction of a relatively good asynchronous TCP server, here is still the same as the first two chapters, give the server code, the code is very detailed comments, I will also give the relevant encapsula

Based on the asynchronous programming of TPL, the simplest is to use a Task object, and the simplest way to create a task object is to use the LAMDA expression: static void Main (string[] args) {//Create the cancellation token source Cancellationtok Ensource Tokensource = new CancellationTokenSource (); Create the cancellation token CancellationToken token = Tokensource.token; int i = 0; int va

This article will mainly explain the differences and advantages and disadvantages of using the "synchronous call", "Asynchronous call", and "Asynchronous callback" to execute the same "addition class" with a delegate. First, use the code to define a delegate and the methods to be called in the following three examples: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighte

The entrusted invoke method is used for Synchronous calling. Synchronous call can also be called blocking call. It will block the current thread and then execute the call. After the call is completed, continue to the next step. Example of synchronous call: using System;using System.Threading;public delegate int AddHandler(int a, int b);public class Foo {static void Main() {Console.WriteLine("**********SyncInvokeTest**************");AddHandler handler = new AddHandler(Add);int result = handler.In

// Declare a delegate Public Delegate string addhandler (int A, string B); // you need to specify the number of parameters here. In this example, there are only two parameters. Void calls asynchronous (){ Addhandler handler = new addhandler (ADD ); // Use begininvoke to start asynchronous operations. Here, 1, "string", the two parameters are corresponding (int A, string B)Iasyncresult result = handl

Using C # to invoke the traditional 32-bit API for serial operation, the entire structure is particularly simple. Receiving data requires only defining data-receiving events.
