Question

I am writing a WPF application using C# and I need some help with threading. I have three classes, each need to be running a task every n seconds in their own thread. This is how I did it with Qt4:

class myThread : public QThread
{
    void run (void)
    {
        while (true)
        {
            mMutex.lock();
            mWaitCondition.wait (&mMutex);

            // Some task

            mMutex.unlock();
        }
    }

    void wait (int timeout)
    {
        // For shutdown purposes
        if (mMutex.tryLock (timeout))
            mMutex.unlock();
    }

    void wake (void)
    {
        mWaitCondition.wakeAll();
    }
}

// Some other class has a timer which ticks
// every n seconds calling the wake function
// of the myThread class.

What I get from this is a controlled update interval. So if I am updating 60 times a second, if the code is slow and can only run 30 times a second, it has no problem doing that, but it will never run more than 60 times a second. It will also not run the same code more than one time at the same time. Whats the easiest way of implementing this in C#?

Answer 1

You should use a Timer instead.
