How to Abort Current task in windows form application c#

Question

I want to provide a button which cancels the present task,

Let's say I want to perform the following task, which takes approximately 30 minutes

 private void CaptureSignal()
  {
        // Capture Signal Code ......
  }

I need to display a button which cancels the current task(any time during the process).

any suggestions...?

Thanks in advance...:)

If your capture is done inside main thread, try this:

bool abort = false;

private void CaptureSignal()
{
    while (!abort) {
    {
        // Capture Signal Code ......
    }
}

private void OnButtonClick(.............)
{
    abort = true;
}

If you're using a BackgroundWorker you can send a cancellation request.
