是什么区别CurrentCulture,InvariantCulture,CurrentUICulture和InstalledUICulture从System.Globalization.CultureInfo？

这是代码:

    private static void CreateCounter()
    {
        if (PerformanceCounterCategory.Exists("DemoCategory"))
            PerformanceCounterCategory.Delete("DemoCategory");

        CounterCreationDataCollection ccdArray = new CounterCreationDataCollection();

        CounterCreationData ccd = new CounterCreationData();
        ccd.CounterName = "RequestsPerSecond";
        ccd.CounterType = PerformanceCounterType.NumberOfItems32;
        ccd.CounterHelp = "Requests per second";
        ccdArray.Add(ccd);

        PerformanceCounterCategory.Create("DemoCategory", "Demo category",
            PerformanceCounterCategoryType.SingleInstance, ccdArray);

        Console.WriteLine("Press any key, to start use the counter");
    }

明显:

PerformanceCounterCategory.Create("DemoCategory", "Demo category", 
     PerformanceCounterCategoryType.SingleInstance, ccdArray);

是抛出异常的行.

我读过PerformanceCounterPermission,我该怎么办？
