Thread management

I want to create a multi threaded feature that will create up to "N" threads.  Once each thread is created I need to be able to track each thread's progress (start, processing, complete).  If all threads are currently used I need to know that so the "N" thread limit is followed.  How is this best achieved?

Check out this free e-book. It's the bible for C# threading.

Hi,
This can be achived using .NET ThreadPool which has controlled mechanism of creation and deletion of threads as used in the application.
Set SetMaxThreads to N threads max-limit which you want  and SetMinThreads to have minimum threads always alive.

Check out the tutorial to use thread pool and mould to your requirement.

Any time you are working with multi-threaded applications the easiest way to do so will be to use the .NET BackgroundWorker.  The BackgroundWorker reports progress, supports cancellation, and has a RunWorkerCompleted event that is raised when it's done doing whatever you ask it to do.

To track the progress of N number of threads, you can simply create a List<BackgroundWorker> of background workers, then cycle through the list and check if the workers in the list are busy.

Following is one my responses regarding BWs from a previous thread:

-------------------

BackgroundWorker is the way to go.  The BW has built in management capabilities, progress reporting, exception handling and cancellation methods that make creating multi-threaded applications quite easy.   The two primary events you will want to concern yourself with are DoWork (code the background thread executes) and RunWorkerCompleted (code to execute when the thread completes).  The BW also has built in exception handling; you can check to see if any exception is thrown when the BW completes.  The RunWorkerAsync() method kicks it off.

BackgroundWorker bw = new BackgroundWorker();
bw.WorkerSupportsCancellation = true;
bw.WorkerReportsProgress = true;
bw.ProgressChanged += new ProgressChangedEventHandler(_bw_ProgressChanged);
bw.DoWork += new DoWorkEventHandler(_bw_DoWork);
bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(_bw_RunWorkerCompleted);
bw.RunWorkerAsync();
