ProgressBar를 사용하여 진행률 업데이트로 BackgroundWorker를 구현하는 방법은 무엇입니까?

<code class="language-xml"><ProgressBar Height="25" Margin="20" Maximum="50" Minimum="0" x:Name="myProgressBar"/></code>

<code class="language-csharp">using System.ComponentModel;
using System.Windows;
using System.Windows.Controls;

public partial class MainWindow : Window
{
    BackgroundWorker backgroundWorker = new BackgroundWorker();

    public MainWindow()
    {
        InitializeComponent();

        backgroundWorker.WorkerReportsProgress = true;
        backgroundWorker.ProgressChanged += BackgroundWorker_ProgressChanged;
        backgroundWorker.DoWork += BackgroundWorker_DoWork;

        backgroundWorker.RunWorkerAsync();
    }

    private void BackgroundWorker_DoWork(object sender, DoWorkEventArgs e)
    {
        for (int i = 0; i < 50; i++)
        {
            System.Threading.Thread.Sleep(100); // 模拟工作
            backgroundWorker.ReportProgress(i);
        }
    }

    private void BackgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        myProgressBar.Value = e.ProgressPercentage;
    }
}</code>
