推荐答案

最简单的方法:

Simplest way:

BackgroundWorker bw;
private void button1_Click(object sender, EventArgs e)
    {
    bw = new BackgroundWorker();
    bw.WorkerSupportsCancellation = true;
    bw.DoWork += new DoWorkEventHandler(bw_DoWork);
    bw.RunWorkerAsync();
    }

void bw_DoWork(object sender, DoWorkEventArgs e)
    {
    BackgroundWorker worker = sender as BackgroundWorker;
    int i = 0;
    while (true)
        {
        if (worker.CancellationPending == true)
            {
            e.Cancel = true;
            break;
            }
        else
            {
            Console.WriteLine(i++);
            System.Threading.Thread.Sleep(500);
            }
        }
    }

private void button2_Click(object sender, EventArgs e)
    {
    if (bw.IsBusy)
        {
        bw.CancelAsync();
        }
    }

请记住，除了原始线程外，您无法与UI元素进行交互-您需要为此调用控件.

Do bear in mind that you can''t interact with UI elements except on the original thread - you will need to invoke the controls for that.
