多线程填充DATAGRRIVIEW遇到问题

Question

当主线程用
              while (T < 1000)
                    {
                        System.Threading.Thread.Sleep(5);
                        if (DataComplete == true)//等待是否完成
                        {
                          break;
                        }
                        T ++;
                        if (T  > 1000)
                        {
                             return;
                        }
                    }
                后，次线程就不工作了。等个WHILE完成后他才开始工作

Answer 1

应该不会的呀，System.Threading.Thread.Sleep()方法是让当前线程睡眠，另外一个线程不受干扰才对，你的子线程是怎么创建的？

Answer 2

  XcFootManagerThread = new Thread(new ThreadStart(XcFootManager.ThreadFillDate));
用这样发方法创建的

Answer 3

我自己也感觉很奇怪。编译成EXE运行的时候没有问题。不过就是调试的时候发现以上的问题

Answer 4

调试的时候，当然会这样了，一行行执行代码，当然要等while循环结束了！

Answer 5

应该是我在执行的时候。System.Threading.Thread.Sleep(5);
  if (DataComplete == true)//等待是否完成
  {
  break;
  }
我的次线程就在填数据，，，填写完成后我这里才能DataComplete == true跳出循环，（编译成EXE是行的），Debug调试的时候就卡在那里了。。这个是正常的么？

Answer 6

  for (int i = 0; i < DsOriginal.Tables[0].Rows.Count; i += DsRows)
            {
                lock (ThreadStateObject)
                {
                    if (ThreadState == 2)
                        break;
                    if (DRowIndex != CurrentRowIndex)
                    {
                        DRowIndex = CurrentRowIndex;
                        WriteLog(CurrentRowIndex.ToString()+"  开始滚动");
                        runNum = Math.Min(DsRows, DsOriginal.Tables[0].Rows.Count - DsRows);
                        
                        FillDataTable(DRowIndex, runNum);
                        WriteLog(runNum.ToString() + "  滚动中");
                        _PageDataComplete = true;
                        WriteLog(CurrentRowIndex.ToString() + "  滚动完成");
                    }
                }
                runNum = Math.Min(DsRows, DsOriginal.Tables[0].Rows.Count - i);
                FillDataTable(i, runNum);
            }这个是次线程的代码

Answer 7

  lock (ThreadStateObject)//锁住
                    {
                        if (ThreadState == 2)
                            break;
                        CurrentRowIndex = y;
                        _PageDataComplete = false;//是否完成变量
                    }
                    while (tryT < 1000)
                    {
                        System.Threading.Thread.Sleep(5);
                       
                        if (_PageDataComplete == true || ThreadState == 0 )//等待是否完成
                        {
                            WriteLogMian(_PageDataComplete.ToString());
                            break;
                        }
                        tryT++;
                        if (tryT > 1000)
                        {
                            WriteLogMian(tryT.ToString());
                            return;
                        }
                    }这个主线程的代码

Answer 8

 if (XcFootManagerThread != null)
                {
                    lock (XcFootManager.ThreadStateObject)
                    {
                        XcFootManager.ThreadState = 2;
                    }
                    int tryT = 20;
                    while (XcFootManagerThread.IsAlive && tryT > 0)
                    {
                        Thread.Sleep(300);
                        tryT--;
                    }
                    if (XcFootManagerThread.IsAlive)
                    {
                        XcFootManagerThread.Abort();
                        Thread.Sleep(1000);
                    }
                }
                XcFootManager.TotalDasetRest();
                XcFootManagerThread = new Thread(new ThreadStart(XcFootManager.ThreadFillDate));
                XcFootManager.ThreadState = 1;
                XcFootManagerThread.Start();开启线程代码

Answer 9

FillDataTable(DRowIndex, runNum);这个函数就是填充数据的
