Winform ProgressBar 控件加载，backgroundWorker事件处理数据

 　　 DialogResult result = MessageBox.Show($"当前失败数据共计{failCount}条,是否上传?", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question);

            if (result == DialogResult.Yes)
            {
                // 后台线程查询数据
                toolStripProgressBar1.Value = 0;
                this.backgroundWorker1.RunWorkerAsync(dataTable);
                //可以禁用其他控件防止出现后台处理数据,出现异常
            }

backgroundWorker事件：

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            if (e.Argument is DataTable scoreUploadTable)
            {
                ScoreUpload scoreUpload = new ScoreUpload();
                int index = 1;
                int count = scoreUploadTable.Rows.Count;　　//获得表数据数量

                foreach (DataRow rowsTable in scoreUploadTable.Rows)
                {
                    scoreUpload = GetRowsInfo(rowsTable);　　//获得对象数据
                    examinterface.QryXml(GetQuerySQL(SqlStatusEnum.UPLOAD, scoreUpload));　　//上传到数据库

                    backgroundWorker1.ReportProgress(index * 100 / count);
                    if (backgroundWorker1.CancellationPending)

                    }
                    index++;
                }
            }
