线程的简单使用

首先要说使用线程一定要只是刷新数据（例如此方法）

//启用线程只需要刷新数据即可，使用于频繁刷新（需注意）
 public void ReshOrder()
        {
            try
            {
                Thread thread = new Thread(
                delegate()
                {
                    dt_BusinessOrder = _customService.getBussinessOrders(UserInfo.uNote1, pId, cId, ccId, UserInfo.uParentId);
                });
                //开启线程刷新数据
                thread.Start();

                rescdgv(dgvBizOrders, dt_BusinessOrder);
                dgvBizOrders.Columns[1].Visible = false;//省ID
                dgvBizOrders.Columns[2].Visible = false;//市ID
                dgvBizOrders.Columns[3].Visible = false;//地区ID
                dgvBizOrders.Columns[4].Visible = false;//商户ID
                if (dgvBizOrders.Rows.Count != 0)
                {
                    IsPlaySound = true;
                }
                else
                {
                    IsPlaySound = false;
                }
            }
            catch { }
        }
