process pipeline in c#

Question

Hi:

I have a loop that spawn new process to run some ".exe" files. And I capture the output of those ".exe" files to my textbox. In order to capture the outputs right away, I can't use process.waitforexit() method. The problem I have right now is if the previous process took a long time to run, a second process will run regardless if the previous one finished or not. This messed up my outputs.

Is there a way for me to insert the processes into a queue structure so it can be run in a sequential order?

Thanks

Answer 1

Sure:

Queue<Process> processes = GetProcesses();
while(processes.Count > 0) {
    Process process = processes.Dequeue();
    // execute process and capture output
}

Here's MSDN on Queue(T).

You could also run the processes parallelly in threads and queue only the output.

However, you would have to use a more complicated locking and notification system.
