c# how to make periodic events in a class?

Question

I want to make a class change one of its properties every second. The change is supposed to happen on class-level and not in the main thread, how would I do this?

Answer 1

You should use System.Threading.Timer:

private System.Threading.Timer timer;

public YourClass()
{
    timer = new System.Threading.Timer(UpdateProperty, null, 1000, 1000);
}

private void UpdateProperty(object state)
{
    lock(this)
    {
        // Update property here.
    }
}

Remember to lock the instance while reading the property because the UpdateProperty is called in a different thread (a ThreadPool thread)
