如何使用带有计时器滴答的BackgroundWorker？

using System.ComponentModel;
using System.Windows.Forms.Timer;

private BackgroundWorker backgroundWorker1 = new BackgroundWorker();
private System.Windows.Forms.Timer timer1 = new System.Windows.Forms.Timer();

backgroundWorker1.WorkerSupportsCancellation = true;
backgroundWorker1.DoWork += new DoWorkEventHandler(backgroundWorker1_DoWork);
backgroundWorker1.RunWorkerCompleted += new RunWorkerCompletedEventHandler(backgroundWorker1_RunWorkerCompleted);

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    BackgroundWorker worker = sender as BackgroundWorker;

    // 在这里执行你的后台任务
    while (!worker.CancellationPending)
    {
        // 在这里执行你的计时器滴答任务
        System.Threading.Thread.Sleep(1000); // 每隔1秒执行一次
    }
}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled)
    {
        // 在这里处理取消操作
    }
    else if (e.Error != null)
    {
        // 在这里处理错误
    }
    else
    {
        // 在这里处理完成后的操作
    }
}

timer1.Interval = 1000; // 每隔1秒触发一次
timer1.Tick += new EventHandler(timer1_Tick);

private void timer1_Tick(object sender, EventArgs e)
{
    // 在这里执行你的计时器滴答任务
}

backgroundWorker1.RunWorkerAsync();
timer1.Start();

backgroundWorker1.CancelAsync();
timer1.Stop();
