C#线程同步

Question

我对 C# 线程有疑问。

1. 我有无穷无尽的进程“worker”，它执行一些操作并在迭代后休眠 3 秒。

2. 我有一个在给定时间运行的计时器函数。

我需要“计时器函数”做一些事情，然后等待“worker”迭代结束，然后暂停“worker”直到“计时器函数”完成自己的任务，之后计时器函数再次启动“worker”。

我该怎么做？最好的问候保罗

您可以使用等待句柄来控制方法 - 类似于:

private AutoResetEvent mWorkerHandle = new AutoResetEvent(initialState: false);
private AutoResetEvent mTimerHandle = new AutoResetEvent(initialState: false);

// ... Inside method that initializes the threads
{
    Thread workerThread = new Thread(new ThreadStart(Worker_DoWork));
    Thread timerThread = new Thread(new ThreadStart(Timer_DoWork));

    workerThread.Start();
    timerThread.Start();

    // Signal the timer to execute
    mTimerHandle.Set();
}

// ... Example thread methods
private void Worker_DoWork()
{
    while (true)
    {
        // Wait until we are signalled
        mWorkerHandle.WaitOne();

        // ... Perform execution ...    

        // Signal the timer
        mTimerHandle.Set();
    }
}

private void Timer_DoWork()
{
    // Signal the worker to do something
    mWorkerHandle.Set();

    // Wait until we get signalled
    mTimerHandle.WaitOne();

    // ... Work has finished, do something ...
}

这应该让您了解如何通过 WaitHandle 控制在其他线程上运行的方法。 (在这种情况下，一个 AutoResetEvent )。
