我有一段从 MSDN https://docs.microsoft.com/en-us/dotnet/api/system.diagnostics.tracing.eventsource?view=netframework-4.7.2借来的示例代码

除此之外，我所做的只是将此代码导入 Visual Studio 控制台应用程序。

为了启动跟踪会话，我尝试了两种方法：

netsh trace start provider={3CADFCE4-5E22-4102-BDC2-5AEA4198CD04}

甚至尝试过 logman create trace sess -pf guids.txt -bs 1000 -nb 100 256 -ow -o tracefiles（guids.txt 有这个唯一的 guid）

吐出 ETL 后，我尝试使用 WPA/netsh 跟踪转换和消息分析器打开它们。这些都没有显示这些事件。

这里有什么问题？

[EventSource(Name = "MyLogger", Guid = "3CADFCE4-5E22-4102-BDC2-5AEA4198CD04")]
class MyCompanyEventSource : EventSource
{
    public static MyCompanyEventSource Log = new MyCompanyEventSource();

    [Event(1, Level = EventLevel.Informational)]
    public void Startup() { WriteEvent(1); }

    [Event(2, Level = EventLevel.Informational)]
    public void OpenFileStart(string fileName) { WriteEvent(2, fileName); }

    [Event(3, Level = EventLevel.Informational)]
    public void LogString(string text) { WriteEvent(3, text); } 
}

    static void Main(string[] args)
    {
        do
        {
            string name = MyCompanyEventSource.GetName(typeof(MyCompanyEventSource));
            IEnumerable<EventSource> eventSources = MyCompanyEventSource.GetSources();
            MyCompanyEventSource.Log.Startup();
            MyCompanyEventSource.Log.OpenFileStart("My Filename");
            MyCompanyEventSource.Log.LogString("Random string");
            Thread.Sleep(1000);
        } while (true);

    }

我希望结果会出现，但我看到的只是：
