如何修复 Xamarin BenchmarkDotNet 错误“只读文件系统”？

如何解决如何修复 Xamarin BenchmarkDotNet 错误“只读文件系统”？

我正在使用 xamarin 创建移动应用程序。 我想使用 BenchmarkDotNet 对某些功能进行基准测试。 当我从 github 运行代码时，它工作正常。 这是截图

但是当我在我的代码中实现它返回 System.IO.IOException: Read-only file system。

这是完整的堆栈跟踪

这是基准代码

    public static class BenchmarkMachine
    {
        public static async Task<string> RunAsync()
        {
            var logger = new AccumulationLogger();
            await Task.Run(() =>
            {
                var config = default(IConfig);
#if DEBUG
                config = new DebugInProcessConfig();
#endif
                var summary = BenchmarkRunner.Run<CommonBenchmark>(config);
                MarkdownExporter.Console.ExportToLog(summary,logger);
                ConclusionHelper.Print(logger,summary.BenchmarksCases
                               .SelectMany(benchmark => benchmark.Config.GetCompositeAnalyser().Analyse(summary))
                               .distinct()
                               .ToList());
            });
            return logger.GetLog();
        }
    }

这里是我想要进行基准测试的代码（只是示例代码）

    [MemoryDiagnoser]
    [Orderer(SummaryOrderPolicy.FastestToslowest)]
    [RankColumn]
    public class CommonBenchmark
    {
        [Benchmark]
        public void Sleep()
        {
            var rand = new Random();
            List<int> vs = new List<int>();
            for (int i = 0; i < 100; i++)
            {
                vs.Add(rand.Next(0,100000));
            }
        }

    }

我使用此代码运行基准测试

string result = await BenchmarkMachine.RunAsync();

我很困惑为什么我的代码不能像 github 中的示例那样工作。 有什么解决办法吗？
