장기 실행 데이터베이스 작업에 BackgroundWorker를 사용할 때 UI 정지를 방지하는 방법은 무엇입니까?

<code class="language-csharp">public class ProgressBarWorker
{
    private ProgressBar progressBar;
    private BackgroundWorker worker;

    public ProgressBarWorker(ProgressBar progressBar)
    {
        this.progressBar = progressBar;
        worker = new BackgroundWorker();
        worker.WorkerReportsProgress = true;
        worker.DoWork += Work;
        worker.ProgressChanged += ProgressChanged; // Added ProgressChanged handler
    }

    public void Run()
    {
        worker.RunWorkerAsync();
    }

    private void Work(object sender, DoWorkEventArgs e)
    {
        // Simulate long-running work; replace with your database operation
        for (int i = 0; i < 100; i++)
        {
            Thread.Sleep(100); // Simulate work
            worker.ReportProgress(i); // Report progress to the main thread
        }
    }

    private void ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        progressBar.Value = e.ProgressPercentage; // Update progress bar on main thread
    }
}</code>

<code class="language-csharp">ProgressBarWorker progressBarWorker = new ProgressBarWorker(progressBar);
progressBarWorker.Run();</code>
