How to get awaitable Thread.Sleep?
提问by Arsen Zahray
I'm writing a network-bound application based on await/sleep paradigm.
我正在编写一个基于等待/睡眠范例的网络绑定应用程序。
Sometimes, connection errors happen, and in my experience it pays to wait for some time and then retry operation again.
有时会发生连接错误，根据我的经验，等待一段时间然后重试操作是值得的。
The problem is that if I use Thread.Sleep or another similar blocking operation in await/async, it blocks all activity in the caller thread.
问题是，如果我在 await/async 中使用 Thread.Sleep 或其他类似的阻塞操作，它会阻塞调用者线程中的所有活动。
What should I replace Thread.Sleep(10000) with to achieve the same effect as
我应该用什么替换 Thread.Sleep(10000) 以达到相同的效果
await Thread.SleepAsync(10000)
?

I'll prefer an answer which does this without creating any additional thread
我更喜欢一个不创建任何额外线程的答案

The other answers suggesting starting a new thread are a bad idea - there's no need to do that at all. Part of the point of async/awaitis to reducethe number of threads your application needs.
建议开始一个新线程的其他答案是一个坏主意 - 根本没有必要这样做。点的一部分async/await是减少线程应用程序需要的数量。
You should instead use Task.Delaywhich doesn'trequire a new thread, and was designed precisely for this purpose:
你应该使用Task.Delay哪并不需要一个新的线程，并且正是为此而设计的：
// Execution of the async method will continue one second later, but without
// blocking.
await Task.Delay(1000);
