BackgroundWorker Cancelation problemček

Imam taksno kodo, ki mi zazene Execute() vsakic, ko pritisnem na gumb.

Ker imam lahko n funkcij, ki jih zaganjam v ozadju me zanima ce obstaja nacin kako cancel-at BackgroundWorker-ja v takem dizajnu.

Zato ker, ko klicem CancelBg se postavi samo CancellatioPending na true, le-tega pa ne morem gledati v delegatu.

pravzaprav bi rabu enostaven Thread.Abort, ki ga pa BackgroundWorker ne podpira.

Kaka ideja?

Ce nacin ne obstaja, bom pac uporabil lasten Threading class, ampak bi raje uporabil BG worker ce se da.

public class RunBG
{
	BackgroundWorker bw;
	public delegate void delExecuteTask();
	delExecuteTask funcToExecute;
	
	public RunBG(delExecuteTask executeFunction)
	{
	    funcToExecute = executeFunction;
	
	    bw = new BackgroundWorker();
	    bw.WorkerReportsProgress = true;
	    bw.WorkerSupportsCancellation = true;
	
	    bw.DoWork += new DoWorkEventHandler(bw_DoWork);
	    
	    bw.RunWorkerAsync();
	}
	
	void bw_DoWork(object sender, DoWorkEventArgs e)
	{
	    funcToExecute.Invoke();
	}
	
	public void CancelBg(object sender, EventArgs e)
	{
	    bw.CancelAsync();
	}
}

// tole je pac en form, ki ima gumb s katerim laufamo bg procese
public class MyForm : Form
{
  // Form stuff
	private void button2_Click(object sender, EventArgs e)
	{
	    RunBG run = new RunBG(Execute);
	}
	
	public void Execute()
	{
	    Thread.Sleep(10000);
	}
}
