Tasks With Timeout Contd.

• Part 1 - Tasks With Timeouts
• Part 2 - Tasks With Timeouts contd.
• Part 3 - Tasks With Timeout on .net4.5

As mentioned in the last post we can now have tasks with individual timeouts. The code looked a little heavy. Can we do better ? Yes we can !!

    var tasks = new List<Task>();
    try
    {
    //instead of checking for fault within the continutaion, 
    //we can just use a TaskContinuationOption to tell communicate the right semantics

    var t1 = Task.Factory.StartNew(_ => LongRunningTask(),TaskCreationOptions.AttachedToParent)
    .TimeoutAfter(1000)
    .ContinueWith(t => SomethingUsefulWithTheResult(), 
     TaskContinuationOptions.NotOnFaulted);

    var t2 = Task.Factory.StartNew(_ => LongRunningTask(), TaskCreationOptions.AttachedToParent)
      .ContinueWith(t => SomethingUsefulWithTheResult());

    var t3 = Task.Factory.StartNew(_ => LongRunningTask("Entering task3"),
    TaskCreationOptions.AttachedToParent)
      .ContinueWith(t => SomethingUsefulWithTheResult());

    tasks.Add(t1);
    tasks.Add(t2);
    tasks.Add(t3);

    Task.WaitAll(tasks.ToArray());
    }
    catch (Exception ex)
    {
    Console.WriteLine("There was an exception");
    Console.WriteLine(ex.InnerException.Message);   
    }

I will show in the next post how this wasn't all that better since this leaves a few gaps.
