c# multithreading

Reprint URL: http://www.knowsky.com/540518.html . NET defines the function of multithreading in the System.Threading namespace. Therefore, to use multiple threads, you must first declare a reference to this namespace (using System.Threading;).A. Start a threadAs the name suggests, "Start a thread" is to create a new and start a thread meaning, the following code can be implemented:Thread thread1 = new Thread (new ThreadStart (Count));The Count is the

C # multithreading and UI response cross-thread UI update, Recently, I was writing a TCP communication program and customized a Communication Class TCPclient for clients to receive and send network messages asynchronously. TCPclient defines a network message event that receives a new message: 1 // receive the new message event 2 public delegate void initialize enewnetworkmsghandler (string networkMSG); 3 pu

One, cross-process access ComponentsError: Invalid inter-thread operation: access it from a thread that is not creating a control "XXX"Workaround:1: Set the Checkforillegalcrossthreadcalls to FalseThis method simply does not catch the call to the wrong thread and does not resolve the problem from the root cause, and the code continues to throw errors that the component is not instantiated.2: Delegate (recommended)Directly on the codepublic delegate void Myinvoke ();p rivate void Setbtnstatus ()

Sometimes, in specific development, we need to design the program into a multi-threaded logic. We simulate this scenario: (C/S Mode) 1. The client sends a measurement command to the server. 2. The server receives measurement commands from the client. 3. The server performs measurement. 4. The server returns the measurement result to the client. The above four steps are a complete interaction process. When we require the server to have multiple client

This section introduces the basic knowledge of threads. Next we will study the priority of multithreading. Using system; Using system.

, incoming 0 returns immediately, incoming infinite means infinite wait.);WaitForSingleObject can wait for a kernel object to be triggered, because the thread is not triggered when it is running , the thread ends and the thread object is in a triggered state, so you can useWaitForSingleObject (H, INFINITE);Wait for a thread to finish executing,function returns,Wait_object_0 object is triggered within the wait timeWait_timeout object has not been triggered within the wait timeWait_failed paramete

The classes that implement threading application development in C # are included in the System.Threading namespace, and the Thread,threadpool class is more commonly usedThe thread class constructor functions as a thread, with two overloaded versions, one with parameters and one without parameters: Public Thread (ThreadStart start); Public Thread (Parameterizedthreadstart start);The declarations of ThreadStart or Parameterizedthreadstart types are as

C # multithreading thread pool, LineThe System. Threading. ThreadPool can be used to send work items, process asynchronous I/O, represent other threads waiting, and process timers. Basic usage: Public void Main () {ThreadPool. queueUserWorkItem (JobForAThread); // submit a job to the thread pool} void JobForAThread (object state) // the job to be executed by the thread: The Job meeting the delegate WaitCall
