关于多线程对数据容器加锁导致线程阻塞

  // 数据接收

             lock (obj)

              {

                   queue1.Enqueue(new KeyValuePair<int, int>(Points[0], Points[2]));

              }



  //UI线程

                       lock (obj)

                       {

                            XYData = XYValue.ToList();

                       }

                       foreach (var keyValuePair in XYData)

                        {

                            lsitX.Add(keyValuePair.Key.ToString());

                            lsitY.Add(keyValuePair.Value);

                        }

                        seriesDraw.Points.DataBindXY(lsitX, lsitY);
