C# - How to work with background worker with custom code -Run,Pause,Stop?

Question

I am working with Background Worker but neither i am able to synchronize my progress bar nor able to stop or abort the process.

in my dowork function

void bw_DoWork(object sender, DoWorkEventArgs e)
{
    if(bw.CancellationPending==true)
    {
        e.cancel=true;
        return;
    }
    else
    {
        e.Result = abc();
    }
}
int abc()
{
    //my work
    Count++;
    return count;
}

void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    if(bw.CancellationPending==true)
    {
        button17.Visibility = Visibility.Visible;
        label1.Content = "Aborted";
    }
    button17.Visibility = Visibility.Visible;
    label1.Content = "Completed";
}
private void Cancel_Click(object sender, RoutedEventArgs e)
{
    if(bw.IsBusy)
    {
        bw.CancelAsync();
    }
}

Now i want to know how could i Synchronize my Progress Bar and how to exit from the process?

Answer 1

Have you set the BackgroundWorker.WorkerReportsProgress && BackgroundWorker.WorkerSupportsCancellation properties on your instance to be true?

e.g.

var myBackgroundWorker = new BackgroundWorker();
myBackgroundWorker.WorkerReportsProgress = true;
myBackgroundWorker.WorkerSupportsCancellation = true;
//the rest of the init

If you want to report progress, you need to call the BackgroundWorker.ReportProgress() method from inside your DoWork.
