三种方式都使用CancellationToken，只是使用方式不同，有类似于采用全局标志位的方式第一种 检测IsCancellationRequested方式 static void AsyncOperation1(CancellationToken token) { Console.WriteLine("starting the fi

一个加减数值的例子说明问题using System;using System.Threading;namespace ThreadLockingDemo{ class Program { static void Main(string[] args) { Console.WriteLine("incorrect c

示例效果与winform中this.invoke(new delegete{})跨线程操作资源类似建立WPF项目，使用4.5框架mainwindow.xml文件如下<Window x:Class="TaskSchedulerDemo.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/prese

贴一种取消任务的方式using System;using System.Threading;using System.Threading.Tasks;namespace CancellationDemo{ class Program { static void Main(string[] args) { var

调用BackgroundWorker相关的方法以下代码参考自《Multithreading in C# 5.0 Cookbook》using System;using System.ComponentModel;using System.Threading;using System.Threading.Tasks;namespace EAPDemo{ class Pro

基于事件的异步模式 (Event-based Asynchronous Pattern, EAP) 异步编程模型 (Asynchronous Programming Model, APM) 基于任务的异步模式 (Task-based Asynchronous Pattern, TAP)换个方式也就是说，将TAP实现原来Thread中的AutoResetEvent、ManualReset

测试函数static async Task RunProgram(){ var taskQueue = new ConcurrentQueue(); var cts = new CancellationTokenSource(); //生成任务添加至并发队列 var taskSource = Task.Run(() => TaskProducer(taskQu

结果已经写在注释中static void Main(string[] args){ var concurrentDictionary = new ConcurrentDictionary(); var dictionary = new Dictionary(); var sw = new Stopwatch(); sw.Start(); for (

static void Main(string[] args) { Console.WriteLine("first time 5s"); RunOperations(TimeSpan.FromSeconds(5)); Console.WriteLine("second time 7s");

BackgroundWorker作用基本就能用名字来表达了具体工作内容函数 static void Worker_DoWork(object sender, DoWorkEventArgs e) { Console.WriteLine("doworker thread pool thread id: {0}", Thread.Curre

UseThreads为手工线程UseThreadPool为线程池方式 static void Main(string[] args) { const int numberOfOperations = 500; var sw = new Stopwatch(); sw.Start();

使用mutex，进行互斥访问示例中运行第一个窗口显示running此时运行第二个窗口显示 空白 处于等待。若在5秒内在第一个窗口中输入，将释放资源，此时第二个窗口将显示runningusing System;using System.Threading;namespace MutexDemo{ class Program { static voi
