C# Thread IsBackground 前后台线程

Thread 区别前后台线程属性IsBackground

1、  创建一个线程默认是前台线程,即IsBackground=true

2、  主线程的结束会关联前台线程,前台线程会阻止主进程的结束,需等待前台线程完成。

3、  主进程结束时后台线程也会结束,即使没有执行完成也会被中断。

  static void Main(string[] args)  {   BackgroundTest shortTest = new BackgroundTest(50);   Thread foregroundThread =    new Thread(new ThreadStart(shortTest.RunLoop));   foregroundThread.Name = "ForegroundThread";   BackgroundTest longTest = new BackgroundTest(100);   Thread backgroundThread =    new Thread(new ThreadStart(longTest.RunLoop));   backgroundThread.Name = "BackgroundThread";   backgroundThread.IsBackground = true;   foregroundThread.Start();   backgroundThread.Start();
   Task.Factory.StartNew(() =>   {    Thread.CurrentThread.Name = "Task Thread";    Thread.CurrentThread.IsBackground = false; //设置为前台线程    new BackgroundTest(50).RunLoop();   });
//回车结束主线程,如果有前台线程在运行是无法结束的,(后台线程就会被终止,不会执行完成)   Console.ReadLine();  }  class BackgroundTest  {   int maxIterations;   public BackgroundTest(int maxIterations)   {    this.maxIterations = maxIterations;   }   public void RunLoop()   {    String threadName = Thread.CurrentThread.Name;    for (int i = 0; i < maxIterations; i++)    {     Console.WriteLine("{0} count: {1}",      threadName, i.ToString());     Thread.Sleep(250);    }    Console.WriteLine("{0} finished counting.", threadName);   }  }
