Show status of each thread

My application runs some threads and every thread does something. I want that each thread shows its status in a list box.

So, how a thread can identify itself (by using thread ID or something else) and set its status into a List?

You could just keep a collection (Array, List, whatever you want) of the Thread you want to monitor. The thread class exposes many properties you may want, including the ThreadState property. From there it is easy to display the informations you want.

This way your working threads will not have to worry about notifying their status.

Every thread has an id. You can access it with 

Thread t;
int id = t.ManagedThreadId;

To update a global datastructure with some state i would use a dictionary and use the id as the key. Be aware of locking the access of that data structure:

Dictionary<int, SomeStateClass> threadStates = new Dictionary<int, SomeStateClass>();

public void updateThreadState(int id, SomeStateClass newState) {
    lock (threadStates) {
        threadStates[id] = newState;
    }
}

You could use Invoke with delegates. Each thread would then be responsible for updating the ListBoxItem it owns.

You can identify managed threads with Thread.CurrentThread.ManagedThreadId. And remember to Invoke calls to your listbox (or use Dispatcher in case you are using WPF), as threads other then UI thread can not access it directly.
