c# - 有没有办法唤醒 sleep 线程？

Question

有没有办法在 C# 中唤醒休眠线程？那么，让它休眠很长时间，然后在您需要处理工作时唤醒它？

Answer 1

安AutoResetEvent对象(或另一个 WaitHandle 实现)可用于休眠，直到收到来自另一个线程的信号:

// launch a calculation thread
var waitHandle = new AutoResetEvent(false);
int result;
var calculationThread = new Thread(
    delegate
    {
        // this code will run on the calculation thread
        result = FactorSomeLargeNumber();
        waitHandle.Set();
    });
calculationThread.Start();

// now that the other thread is launched, we can do something else.
DoOtherStuff();

// we've run out of other stuff to do, so sleep until calculation thread finishes
waitHandle.WaitOne();
