WebAug 19, 2015 · Using AsyncLock is straightforward: private readonly AsyncLock _mutex = new AsyncLock (); public async Task UseLockAsync () { // AsyncLock can be locked asynchronously using (await _mutex.LockAsync ()) { // It's safe to await while the lock is held await Task.Delay (TimeSpan.FromSeconds (1)); } } Web当所有在.await调用中持有的数据被Send，任务就能被发送。 当.await被调用时，任务就回到了调度器中。下一次任务被执行时，它将从最后的上次yield点恢复。 为了使其正常工作，所有在.await之后使用的状态都必须由任务保存。

WebJan 8, 2013 · Awaiting inside a lock is a recipe for producing deadlocks.
