How to stop the background worker while working

I am new to c sharp. I created a windows form application. my application is working fine. I want to cancel BackgroundWorker while working. I want to completely stop the BackgroundWorker process. I use this code to cancel the application, 1) first I used

    private void exitToolStripMenuItem_Click(object sender, EventArgs e)
    {

        this.Dispose();
    }

but he does not stop. then i used

    private void exitToolStripMenuItem_Click(object sender, EventArgs e)
    {
        bgBackfill1.CancelAsync();
        this.Dispose();
    }

but when I exit the application, it writes files to G: \ Drive. can someone tell me how can I stop writing files to G: \ Drive and complete the BackgroundWorker process completely.

Thanks if someone helps me.

The desktop worker method must know that cancellation is expected, so only then can it cancel.

private void bw_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;

    for (int i = 1; (i <= 10); i++)
    {
        if ((worker.CancellationPending == true))
        {
            e.Cancel = true;
            break;
        }
        else
        {
            // Perform a time consuming operation and report progress.
            System.Threading.Thread.Sleep(500);
            worker.ReportProgress((i * 10));
        }
    }
}

You must set the WorkerSupportsCancellation property when the component is initialized BackgroundWorkerand before the call RunWorkerAsync. So for example:

MyWorker = new BackgroundWorker();
MyWorker.WorkerSupportsCancellation = true;
MyWorker.WorkerReportsProgress = true;
MyWorker.DoWork += DoWorkEventHandler;
MyWorker.ProgressChanged += WorkerProgressChanged;
MyWorker.RunWorkerAsync();
