Using A System.Threading.Timer To Implement A TimeOut Feature

// The Timer delegate to be invoked on a callback (from 
// another thread)
protected void TimeOut(object obj)
{
  lock(accesslock) // Careful. TimeOut callback occurs on 
another thread
  {
    log.Error("Something TIMED OUT, will take action");
    TakeTimeOutAction();
  }
}
...
// Example usage
using (Timer timer = new Timer(new TimerCallback(TimeOut), null,
 10000L, Timeout.Infinite))
{
  while (!complete)
  {
    log.Debug("Something waiting for something else to complete");     
    Thread.Sleep(1000);
  }
}
