join t.start() t.join() Wait until the thread terminates. This blocks the calling thread until the thread whose join() method called terminates -- either normally or through an unhandled or until the optional timeout occurs. 将子线程join之后,主线程会等待这些join的子
1.Thread.join([timeout]) Wait until the thread terminates. This blocks the calling thread until the thread whose join() method is called terminates – either normally or through an unhandled exception – or until the optional timeout occurs. 等待进程结束.也就是
thread.Join把指定的线程加入到当前线程,可以将两个交替执行的线程合并为顺序执行的线程.比如在线程B中调用了线程A的Join()方法,直到线程A执行完毕后,才会继续执行线程B.t.join(); //使调用线程 t 在此之前执行完毕.t.join(1000); //等待 t 线程,等待时间是1000毫秒 先上一段JDK中代码: /** * Waits at most <code>millis</code> milliseconds for this threa
这两个方法 可以说是类似的功能,都是对当前任务进行等待阻塞,执行完毕后再进行后续处理 talk is cheap, show you code,下面一个是异步执行,一个是加了阻塞,可以对比不同执行结果 public static void TaskThreadTest() { Stopwatch watch = new Stopwatch(); watch.Start(); Thread thread = new Thread(new ThreadStart(ThreadFunction));
