Answer 1

private void toolStripButtonUpload_Click(object sender, EventArgs e)
 {
            try
            {
 //其它操作

                this.backgroundWorkerUpload.RunWorkerAsync(list);
            }
            catch (Exception ex)
            {
                this.toolStripButtonUpload.Enabled = true;                this.m_Helper.ShowException(ex);
            }
        }        //进度显示
        private void backgroundWorkerUpload_ProgressChanged(object sender, ProgressChangedEventArgs e)
        {
            this.progressBar.Value = e.ProgressPercentage;            this.labTip.Text = string.Format("{0}", Properties.Resources.Message_Executing);
            this.progressBarLabTip.Text = string.Format("{0}%", e.ProgressPercentage);
 
        }        //操作完成  出现错误的时候会调用此方法
        private void backgroundWorkerUpload_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            this.progressBar.Visible = false;
            this.progressBarLabTip.Visible = false;
            this.labTip.Text = Properties.Resources.Message_LabTipDefaultText;            this.toolStripButtonUpload.Enabled = true;
            this.toolStripButtonUploadCancel.Enabled = false;
        }

        //执行数据操作 不能操作界面上的东西
        private void backgroundWorkerUpload_DoWork(object sender, DoWorkEventArgs e)
        {
            Cursor.Current = Cursors.AppStarting;            try
            {     
                        LogisticsHelper.LogisticsServiceProxy.AddPUPArchive(this.m_Helper.Ticket, info);                        worker.ReportProgress((int)((float)(completed) / (float)total * 100), new ProgressUserState(true, info, null));
             }
             catch (Exception ex)
               {
                       worker.ReportProgress((int)((float)(completed) / (float)total * 100), new ProgressUserState(false, info, ex));
               }
                    completed++;
                }
            }
