如何将类内的进度报告给BackgroundWorker？

BackgroundWorker worker;

public MyClass()
{
    worker = new BackgroundWorker();
    worker.WorkerReportsProgress = true;
    worker.DoWork += Worker_DoWork;
    worker.ProgressChanged += Worker_ProgressChanged;
    worker.RunWorkerCompleted += Worker_RunWorkerCompleted;
}

private void Worker_DoWork(object sender, DoWorkEventArgs e)
{
    // 后台任务的逻辑代码
    for (int i = 0; i < 100; i++)
    {
        // 执行任务的某个步骤
        // 报告进度给BackgroundWorker
        worker.ReportProgress(i);
    }
}

private void Worker_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
    // 获取进度值
    int progress = e.ProgressPercentage;

    // 更新UI或执行其他操作
    // 例如，更新进度条的值
    progressBar.Value = progress;
}

private void Worker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    // 后台任务完成后的处理逻辑
    // 例如，显示任务完成消息
    MessageBox.Show("任务已完成！");
}
