有没有办法知道BlockingCollection中的所有任务何时完成执行?(任务将在启动时删除,但我想知道exec是否完成)[已关闭]

我正在尝试创建一个单一消费者和多个生产者的模式。生产者将向BlockingCollection添加任务,消费者将运行这些任务。我想知道是否有办法知道由消费者产生的所有任务的执行是否完成。

public TaskQueue(IProducerConsumerCollection<Task> workTaskCollection)
        {
            _workTaskQueue = new BlockingCollection<Task>(workTaskCollection);
        }

        public void EnqueueTask(Action action, CancellationToken cancelToken = default(CancellationToken))
        {
            var task = new Task(action, cancelToken);
            if (_workTaskQueue.TryAdd(task))
            {
                TaskHandler?.Invoke
                    (new TaskProcessingArguments
                    {
                        ISTaskAdded = true,
                        Message = "Task Added to Queue",
                        PendingTaskCount = _workTaskQueue.Count,
                    });
            }
            else
            {
                TaskHandler?.Invoke
                    (new TaskProcessingArguments
                    {
                        ISTaskAdded = false,
                        Message = "Timedout while adding Task to Queue",
                        PendingTaskCount = _workTaskQueue.Count,
                    });
            }
        }


        public void DequeueTask()
        {
            foreach (var task in _workTaskQueue.GetConsumingEnumerable())
                try
                {
                    if (!(task.IsCanceled) && task.Status == TaskStatus.Created)
                    {
                        task.Start();
                    }
                }
                catch (Exception ex)
                {

                }
        }
        public static void Run()
                {
                    Task.Factory.StartNew(() =>
                    {
                            taskQueue.DequeueTask();

                    }, TaskCreationOptions.LongRunning);
                }
