我正在使用 Rx 2.0 的 EventLoopScheduler 来排队/序列化工作。当我需要处置调度程序时,如果还有剩余工作,我将收到未处理的 ObjectDisposedException。这是预期的行为吗?
人为/示例代码:
EventLoopScheduler scheduler = new EventLoopScheduler();
List<IDisposable> handles = new List<IDisposable>();
for (int i = 0; i < 100; ++i)
{
var handle = Observable.Interval(TimeSpan.FromMilliseconds(1))
.ObserveOn(scheduler)
.Subscribe(Observer.Create<long>((x) => Thread.Sleep(1000)));
handles.Add(handle);
}
Thread.Sleep(TimeSpan.FromSeconds(1));
foreach (var handle in handles)
handle.Dispose();
scheduler.Dispose();
Console.ReadLine();
