Question

我可以使用什么操作来模拟相对昂贵的过程

public void SimulateLongProcess()
{
   //Do Something that takes a few seconds to perform on a quadcode CPU
}

我想避免任何线程等待，也不要涉及IO。一些数学运算可以做......

Answer 1

不确定你到底需要什么。您可以在我的机器上执行以下操作，大约需要2900毫秒。此代码无法确保准确的执行时间，执行时间因机器而异。您可能想根据需要调整它。

        Stopwatch stopWatch = new Stopwatch();
        stopWatch.Start();

        for (int i = 0; i < 10000000; i++)
        {
            double test = 1000; 
            test = (test * 100000.00001)/100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;
            test = (test * 100000.00001) / 100000.123123;

        }

        stopWatch.Stop();
        var executionTime = stopWatch.ElapsedMilliseconds;

Answer 2

作为一个非常虚拟的东西，你可以运行一个for循环

for (int i = 0; i < 1000000000; i++)
{
    var str = "dummy";
}

Thread.Sleep会更准确。确保仅将其用于测试

建议为测试目的进行长期操作
