POFOR LOOP within Callback procedure in System.Threading.Timer causes it to fire only ONCE
text
Body
copied!<p>At the moment I have a For loop within a Callaback procedure :</p> <pre><code>private void InitializeComponent() { var timer = new System.Threading.Timer(TimerProc, null, 60000, 60000); } public void TimerProc(object state) { for (int i = 0; i <= 6; i++) { //Do something here } } </code></pre> <p>TimerProc only fires ONCE despite the fact that I have it set to repeat every 60000 milliseconds. It looks like that the operations within the loop are no longer executed after they are completed the first time around.</p> <p>However, if I remove the For loop and have some other action like print to a console line or write to a text file then TimerProc repeats as expected.</p> <p>Why is this the case and why does a loop with in a Callback procedure stop it from executing after its initial firing?</p> <p>I have made a workaround by using a while(true) infinte loop and using the Thread.Timer to pause the process after x amount of milliseconds.</p> <p>My new vised code with the while loop looks like this:</p> <pre><code>private void InitializeComponent() { processthread = new Thread(new ThreadStart(DoSomething)); processthread.Start(); } public void DoSomething() { while(true) { for (int i = 0; i <= 6; i++) { //do something here } Thread.Sleep(5000); } } </code></pre> <p>I just want to know why callback procedure in the System.Thread.Timer cannot handle loops.</p> <p>Cheers,</p> <p>Stanley</p>
