我正在使用10个线程，每个线程获取10条状态为null的记录，然后 将状态更新为“ Q”。现在将这些记录请求给不同的API，并在成功响应后将状态更新为“ C”，一切都很好。作为停止所有线程的停止器，我在（j> 30）ManualResetEven.Set（）我检查条件后使用了ManualResetEvent
if (_stopper.WaitOne(0, false))
{
break;
}
要停止我的while循环并将状态为“ Q”的每个线程的其余记录的状态更新为null。在停止我将10个线程的所有记录的状态用“ Q”的状态更新为null时，问题是线程记录的记录不是从“ Q”状态更新为null吗？
这是我的代码：

int j = 1;
while (true)
{
if (_stopper.WaitOne(0, false))
{
lov.LogWriter("MainProcess stopper. |" + dt.Rows[0]["que_batch"].ToString());
string var = sp_Queue_upd(dt.Rows[0]["que_batch"].ToString(), "Q");
lov.LogWriter("MainProcess stopper sp_Queue_upd " + var + " stopper call, current number is " + que_BatchNumberIndex + " Batch No. :" + que_BatchNumber + ": mainthread End of While");//+ (string)argArray.GetValue(1));
break;
}
if (j > 30)
{
_stopper.Set();
lov.LogWriter("MainProcess stopper.Set");
}
if (threadCount.ThreadCount < totalThread && threadCount.ThreadCount >= 0)
{
if (ThreadNum[threadCount.ThreadCount] == null)
{
dt = sp_get_entry_spool();
if (dt.Rows.Count <= 0)
{
Thread.Sleep(1000);
continue;
}
object[] objArr = { dt, threadCount.ThreadCount.ToString(), dt.Rows[0]["que_batch"].ToString() };
ThreadNum[threadCount.ThreadCount] = new Thread(new ParameterizedThreadStart(Process));
ThreadNum[threadCount.ThreadCount].Name = dt.Rows[0]["que_batch"].ToString();
ThreadNum[threadCount.ThreadCount].IsBackground = true;
ThreadNum[threadCount.ThreadCount].SetApartmentState(ApartmentState.MTA);
ThreadNum[threadCount.ThreadCount].Start(objArr);
lov.LogWriter("thread Start: Batch No. :" + dt.Rows[0]["que_batch"].ToString() + "|Actual Batch :" + j + "|ThreadCount" + threadCount.ThreadCount.ToString());
