How to add a "BackGroundWorker" in "ThreadPool"

Question

Everyone, As we know, "ThreadPool" is a static type, so we can't "new" a "ThreadPool. If I use the code

BackgroundWorker worker = new BackgroundWorker();

how am I supposed to add this "workers" to "ThreadPool"? Thanks

You don't. Check the following example:

        public Form1()
        {
            InitializeComponent();
            backgroundWorker1.WorkerReportsProgress = true;
            backgroundWorker1.WorkerSupportsCancellation = true;
        }

        private void startAsyncButton_Click(object sender, EventArgs e)
        {
            if (backgroundWorker1.IsBusy != true)
            {
                // Start the asynchronous operation.
                backgroundWorker1.RunWorkerAsync();
            }
        }

See the call to RunWorkerAsync. This handles the asynchronous execution of the background process, without you worrying about the thread pool.
