在WinForm应用程序中进行批处理时,如何让UI线程更新UI？

private void button1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        // 执行批处理任务
        label1.Text = i.ToString();
        Application.DoEvents(); // 处理UI消息队列中的消息，使UI线程能够更新UI
        System.Threading.Thread.Sleep(100); // 模拟批处理任务耗时
    }
}

private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync(); // 开始执行后台任务
}

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        // 执行批处理任务
        backgroundWorker1.ReportProgress(i); // 通过ReportProgress方法在UI线程中更新UI
        System.Threading.Thread.Sleep(100); // 模拟批处理任务耗时
    }
}

private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    label1.Text = e.ProgressPercentage.ToString(); // 更新UI
}

private async void button1_Click(object sender, EventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        // 执行批处理任务
        await Task.Run(() =>
        {
            label1.Invoke((MethodInvoker)delegate
            {
                label1.Text = i.ToString(); // 更新UI
            });
            System.Threading.Thread.Sleep(100); // 模拟批处理任务耗时
        });
    }
}
