结合ManualResetEvent和token.WaitHandle.WaitOne

Question

I got:

internal void Start(CancellationToken token)
{
   while (!token.IsCancellationRequested)
   {
       //do work
       token.WaitHandle.WaitOne(TimeSpan.FromSeconds(67));
   }       
}

So i start this method in new Task and do some work in loop untill i need to cancel it with token Some times i need to force new loop iteration, without waiting this 67 seconds. I think i need something like:

public ManualResetEvent ForceLoopIteration { get; set; }

Meanwhile i cant understand how to use it with token. Maybe something like WaitHandle.WaitAny() ?

Answer 1

Youre on the right way, try this:

WaitHandle.WaitAny(
    new[] { token.WaitHandle, ForceLoopIteration },
    TimeSpan.FromSeconds(67));

This waits for the occurence of one of the following

• cancelation is requested on token
• ForceLoopIteration is set
• timeout of 67 seconds has been elapsed
