如何“睡觉”？直到在.NET 4.0中请求超时或取消 [英] How to "sleep" until timeout or cancellation is requested in .NET 4.0

问题描述

最好的睡眠时间是什么，但是可以被 CancellationToken IsCancellationRequested 打断$ c>？

What's the best way to sleep a certain amount of time, but be able to be interrupted by a IsCancellationRequested from a CancellationToken?

我正在寻找一种适用于.NET 4.0的解决方案。

I'm looking for a solution which works in .NET 4.0.

I' d想写

void MyFunc (CancellationToken ct)
{
   //... 
   // simulate some long lasting operation that should be cancelable 
   Thread.Sleep(TimeSpan.FromMilliseconds(10000), ct); 
}

推荐答案

我只是在这里写博客：

CancellationToken和Thread.Sleep

简而言之：

var cancelled = token.WaitHandle.WaitOne(TimeSpan.FromSeconds(5));

在您的上下文中：

void MyFunc (CancellationToken ct)
{
   //... 
   // simulate some long lasting operation that should be cancelable 
   var cancelled = ct.WaitHandle.WaitOne(TimeSpan.FromSeconds(10));
}
