I have accomplished a similar task in the past using a variation of this code:
C#
public sealed class ExtendedBackgroundWorker : BackgroundWorker
{
  private Thread thread;
  public void Stop()
  {
    thread?.Abort(); // Abort the thread if it has been set.
	thread = null;
  }
  protected override void OnDoWork(DoWorkEventArgs eventArgs)
  {
    thread = Thread.CurrentThread;
	try
	{
	  base.OnDoWork(eventArgs);
	}
	catch (ThreadAbortException threadAbort)
	{
	  Debug.WriteLine("ExtendedBackgroundWorker has been aborted");
	  Thread.ResetAbort();
	  eventArgs.Cancel = true;
	}
  }
}
With this, you're going to Abort the Thread. Now, an Abort is normally a bad method to call (there are various resources you can look up about why it's not recommended), but we're going to handle it in a controlled manner. When the thread is aborted, a ThreadAbortException is raised so, in our OnDoWork handler, we want to Cancel the DoWorkEventArgs and reset the Abort so that it doesn't destabilise our system. Now, you have a background worker that can be killed from the calling code. By the way, I call the method Stop rather than Abort because while this code is carefully written to prevent Abort issues, I don't want people to get into the habit of calling Abort wherever they see thread codes. By hiding the implementation, I'm hiding the idea that Abort should be called.
