@DanialEugen And the thread-safe solution for using List is to use a lock, I already said that twice. Also, no, you can't use Count or any other member of List without a lock, none of the members of List are thread-safe.

@DanialEugen Not necessarily. You could move just JobTriggered() and not JobException(), if that makes the most sense for you.

@DanialEugen I don't understand, you're not “subscribing” to JobTriggered, you call it. So instead of JobTriggered(job), you would call job.JobTriggered().

| Aug 12, 2014 at 5:17 | comment | added | Danial Eugen | ah sorry and can you point me to a thread safe solution for the list prob because from what i see List and Thread Safe don't mix :P | |
| Aug 12, 2014 at 4:08 | comment | added | Danial Eugen | also does _jobs.Count count for thread-safety ? or i can use it without lock | |
| Aug 12, 2014 at 3:42 | comment | added | Danial Eugen | ok that makes sense... Also the reason i made the JobTriggered method a part of the scheduler and not the job is that i want to subscribe to it only one time and not subscribing every time i add a new job ? what about that | |

@DanialEugen You're accessing _jobs from two threads (the one that executes ProcessJobs() and the one that executes AddJob()), and the accesses can happen at the same time. And since List<T> is not thread-safe, your code is not thread-safe. The simplest way to fix that is to access _jobs always under a lock, so that the accesses from different threads can't happen at the same time. In general, you might want to learn more thread-safety if you want to build multi-threaded applications.

Well some explanations, 1- by saying DataFlow like i was pointing out to the whole thing not the statement behind it only. 2- As i run in trouble using async i just used Wait() as it does the same as i want (which is not executing a job before the other (the dataflow thingy). 3- I don't understand the first part about thread safety so can you be more accurate with some code examples ?
