暂停并恢复Parallel.ForEach [英] Pausing and resuming Parallel.ForEach
问题描述
我需要在某种情况下能够暂停Parallel.ForEach。
I need at some condition to be able pause Parallel.ForEach.
如果发生某些情况，我需要等到所有已经运行的线程完成，然后执行一些操作继续foreach执行
If some condition happened, I need to wait until all already running threads complete, then perform some action the continue foreach execution
Parallel.ForEach(mAFGuidList,
newParallelOptions { MaxDegreeOfParallelism = parallelDegree },
( m , state)=>{
//-------------------------------
Interlocked.Increment(refcallCount);
if(callCount % 500== 0)
{
1. Pause Execution and wait antill started earlier threads are
2. Prform some action
3. Resume execution
}
//----------------------------
DoSomeWork();
}
可以这样做吗？
