BackgroundWorker问题

Question

  private void backgroundWorker2_DoWork(object sender, DoWorkEventArgs e)
        {
            for (int i = 0; i < 10; ++i)
            {
                Thread.Sleep(500);
                backgroundWorker2.ReportProgress(i * 10);
                if (backgroundWorker2.CancellationPending)
                {
                    e.Cancel = true;
                    return;
                }
            }
            e.Result = sr.Search(agent, start, end);
        }
        private void backgroundWorker2_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            dataGridView1.DataSource = e.Result;
            progressBar1.Value = 0;
        }

        private void backgroundWorker2_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            this.progressBar1.Value = e.ProgressPercentage;
        }

 

 

报错:此 BackgroundWorker 声明它不报告进度。请修改 WorkerReportsProgress 以声明它报告进度。

你好

你可以加以下的CODE 去 声明它报告进度

backgroundWorker2.WorkerReportsProgress=True

Please correct me if my concept is wrong
