以下代码的结果不同如果它在后台启动调试器或没有调试器.如果开启优化,那么差异就在那里.

这是结果:

- >与优化:1000 2008 3016 1001 2009 3007 ...

- >无优化(如预期)1000 1008 1016 1001 1009 1017 ...

码:

using System;
using System.Diagnostics;
using System.Runtime.CompilerServices;

namespace OptimizerTest
{   
    public class Test
    {
        int dummy;

        public void TestFunction(int stepWidth)
        // stepWidth must be a parameter
        {
            for (int step = 0; step < stepWidth; step++)
            {
                dummy = step + 1000;
                // addition with constant ( same value as later !)
                for (int x = 0; x < 20; x += …
