WinApp C# ช่วยหน่อยครับ ผมใช้งาน RunWorkerAsync(object ) ใน BackgroundWorker ไม่เป็นครับ

 private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
           /* for (int i = 1; i <= 10000; i++)
            {
                this.workerProgressbar1.ReportProgress((double)i * 100 / 10000);
                this.Invoke(new Action(() => { this.Text = "" + i; }));
                System.Threading.Thread.Sleep(100);
            }*/
        }

        private void backgroundWorker1_ProgressChanged(object sender, TORServices.FormsTor._ProgressChangedEventArgs e)
        {
            label1.Invoke(new Action(() => { label1.Text =  e.ProgressPercentage.ToString("0.0000") + " %"; }));
            this.workerProgressbar1.Invoke(new Action(() => { workerProgressbar1.Value = (int)e.ProgressPercentage; }));
        }

        private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            MessageBox.Show("Complete...");
        }

        void Run_1()
        {
            MessageBox.Show("Test Run");
            for (int i = 1; i <= 10000; i++)
            {
                this.workerProgressbar1.ReportProgress((double)i * 100 / 10000);
                this.Invoke(new Action(() => { this.Text = "" + i; }));
                System.Threading.Thread.Sleep(100);
            }
        }
        private void button1_Click(object sender, EventArgs e)
        {
            workerProgressbar1.RunWorkerAsync(new System.Threading.ThreadStart(Run_1));
          
        }
